The main cause of global warming

The main cause of global warming

It took more than 20 years to broadly accept that mankind is causing global warming with the emission of greenhouse gases. The drastic increase in the emission of CO2 (carbon dioxide) within the last 30 years caused by burning fossil fuels has been identified as the major reason for the change of temperature in the atmosphere (click the following link for a summary and graphs about the cause and effects of global warming ). More than 80% of the world-wide energy demand is currently supplied by the fossil fuels coal, oil or gas. It will be impossible to find alternative sources, which could replace fossil fuels in the short or medium term. The energy demand is simply too high.
Another issue is the non-renewable characteristic of fossil fuels: It took nature millions of years to generate these resources, however we will have used them up within the next decades. Alone the shrinking supply will not make it possible to continue as usual for a longer time.

The main cause of global warming is our treatment of Nature

• Why have warnings about climate change been ignored for more than 20 years?

• Why were ever more scientific evidence demanded to find the coherence of man-made CO2 emissions as cause of global warming? Why wasn't common sense reason enough to act?

• The true cause of global warming is our thoughtless attitude to Nature.

  Why can one still today find people who stick their head in the sand and don't want to understand what's going on in the earth's atmosphere?

• Why do most people refuse to change their personal behavior voluntary in order to reduce CO2 emissions caused by their activities?

The answer to all these questions is a rather simple one:

In our technology and scientific minded world, we seem to have forgotten that mankind is only a relatively minor part of Nature. We ignore being part of a larger whole.

We believe to be able to control Nature instead of trying to arrange ourselves with Nature. This haughtiness is the true main cause of global warming. As a matter of fact, some people still believe that technical solutions alone would be sufficient to fight global warming.
Although we are guests on Earth, we behave as if no further visitors would arrive after us. It's like having a wild party where we destroy beds, the kitchen as well as the living room of a hotel without ever thinking about our future staying in the hotel nor about other guests arriving later.

The lesson from global warming is to base all decisions on deep respect and consideration for Nature.

In addition, our unit of measure is more and more often money only. What has no price tag, seems to have no value to us any more. In doing so we mix up economic growth with general well-being and financial income with personal happiness, respectively. There is a loss of value behind this attitudes. We got blind for the true reason of our incarnation on earth:

We live here to train those traits , which will finally lead to perpetual harmony with ourselves and with our environment as well as to inner calm and peace.

 

The ultimate global warming solutions is to behave as part of a larger whole

Many people between 20 and 65 years seem to live for the one and only purpose of earning as much money as possible in order to be able to buy as many things as possible. In this light, it is not surprising that discussions about potential solutions to fight global warming concentrate on technical measures instead of a fundamental change of our attitude to life in general and to Nature in particular.
Someone who respects Nature and regards mankind as a part of a larger whole would never dream about using up non-renewable resources in a short time nor would this person contaminate the environment with gigantic amounts of pollution. By contrary, someone who respects Nature and regards mankind as a part of a larger whole would in all decisions carefully evaluate any effects on Nature. The preservation of Nature would be given a very high priority. On this base, it wouldn't have been possible to deny and ignore global warming for more than 20 years!

It's your personal decision whether you want to be the cause of global warming

In this context the question is whether global warming and its effects will eventually wake up mankind and spark off a change of paradigm. Will we understand this hint of Nature to follow the true meaning of life or will we continue to let us manipulate by media and advertisement as sheer and willing consumers in the economic cycle? Will we continue to strive for power, prestige and possessions following the concept „the more the better "? Shall economic growth and an ever increasing personal income continue to be the reason for being here, beyond everything else?
These questions can and must be answered by everyone. It is not primarily a decision of politicians or of the government. Everyone has to make a personal decision.
It is in our very own interest to induce fundamental changes in our attitude and behavior towards Nature: Modesty and humility, admiration and respect for all life on Earth instead of arrogance and haughtiness.
Let's emphasize it again: Not the others need to change, we must change ourselves. There are no international treaties or additional national laws required to start changing. We can start to change our consciousness immediately. It is really only about our personal behaviour - independent of what others do or don't do.
It's time for change!

Brief on Ozone Depletion

Brief  on Ozone Depletion

What is the ozone layer and why is it important?

The ozone layer is a concentration of ozone molecules in the stratosphere. About 90% of the planet's ozone is in the ozone layer. The layer of the Earth's atmosphere that surrounds us is called the troposphere. The stratosphere, the next higher layer, extends about 10-50 kilometers above the Earth's surface. Stratospheric ozone is a naturally-occurring gas that filters the sun's ultraviolet (UV) radiation. A diminished ozone layer allows more radiation to reach the Earth's surface. For people, overexposure to UV rays can lead to skin cancer, cataracts, and weakened immune systems. Increased UV can also lead to reduced crop yield and disruptions in the marine food chain. UV also has other harmful effects.

 

How does ozone depletion occur?

It is caused by the release of chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs), and other ozone-depleting substances (ODS), which were used widely as refrigerants, insulating foams, and solvents. The discussion below focuses on CFCs, but is relevant to all ODS. Although CFCs are heavier than air, they are eventually carried into the stratosphere in a process that can take as long as 2 to 5 years. Measurements of CFCs in the stratosphere are made from balloons, aircraft, and satellites.
When CFCs and HCFCs reach the stratosphere, the ultraviolet radiation from the sun causes them to break apart and release chlorine atoms which react with ozone, starting chemical cycles of ozone destruction that deplete the ozone layer. One chlorine atom can break apart more than 100,000 ozone molecules.
Other chemicals that damage the ozone layer include methyl bromide (used as a pesticide), halons (used in fire extinguishers), and methyl chloroform (used as a solvent in industrial processes for essential applications). As methyl bromide and halons are broken apart, they release bromine atoms, which are 60 times more destructive to ozone molecules than chlorine atoms.

 

How do we know that natural sources are not responsible for ozone depletion?

While it is true that volcanoes and oceans release large amounts of chlorine, the chlorine from these sources is easily dissolved in water and washes out of the atmosphere in rain. In contrast, CFCs are not broken down in the lower atmosphere and do not dissolve in water. The chlorine in these human-made molecules does reach the stratosphere. Measurements show that the increase in stratospheric chlorine since 1985 matches the amount released from CFCs and other ozone-depleting substances produced and released by human activities.

 

What is being done about ozone depletion?

In 1978, the use of CFC propellants in spray cans was banned in the U.S. In the 1980s, the Antarctic "ozone hole" appeared and an international science assessment more strongly linked the release of CFCs and ozone depletion. It became evident that a stronger worldwide response was needed. In 1987, the Montreal Protocol was signed and the signatory nations committed themselves to a reduction in the use of CFCs and other ozone-depleting substances.
Since that time, the treaty has been amended multiple times to accelerate the phaseout of CFCs, HCFCs, and other ozone depleting substances. Today, over 190 countries have ratified the treaty. For over a decade the production of CFCs has been banned, with limited exceptions for essential uses. The next step in the elimination of ozone depleting substances occurs in 2010 when EPA will ban the production of the most harmful HCFCs. This production phaseout is possible because of efforts to ensure that there are substitute chemicals and technologies for the compounds being phased out.
EPA coordinates numerous regulatory programs designed to help the ozone layer and continues to be active in developing international ozone protection policies. Individuals can also help, primarily by ensuring that technicians working on air conditioning and refrigeration equipment are certified by EPA, that refrigerants are recaptured and not released, and by educating themselves about the issue of ozone depletion.

 

Is there general agreement among scientists on the science of ozone depletion?

Yes, an international consensus about the causes and effects of ozone depletion has emerged. Under the sponsorship of the UN Environment Programme (UNEP)  and the World Meteorological Organization (WMO) , the scientific community issues periodic reports on the science of ozone depletion. Over 300 scientists worldwide drafted and reviewed the most recent analysis, WMO/UNEP Scientific Assessment of Ozone Depletion:

 

Will the ozone layer recover? Can we make more ozone to fill in the hole?

Provided that we stop producing ozone-depleting substances, ozone will be created through natural processes that should return the ozone layer to normal levels by about 2050. It is very important that the world comply with the Montreal Protocol; delays in ending production could result in additional damage and prolong the ozone layer's recovery.

The Ozone Layer

Ozone is a gas that occurs naturally in our atmosphere. Most of it is concentrated in the ozone layer, a region located in the stratosphere several miles above the surface of the Earth. Although ozone represents only a small fraction of the gas present in the atmosphere, it plays a vital role by shielding humans and other life from harmful ultraviolet light from the Sun. Human activities in the last several decades have produced chemicals, such as chlorofluorocarbons (CFCs), which have been released into the atmosphere and have contributed to the depletion of this important protective layer. When scientists realized the destructive effect these chemicals could have on the ozone layer, international agreements were put in place to limit such emissions. As a result, it is expected that the ozone layer will recover in the coming decades.

Ozone is also a greenhouse gas in the upper atmosphere and, therefore, plays a role in Earth's climate. The increases in primary greenhouse gases, such as carbon dioxide, may affect how the ozone layer recovers in coming years. Understanding precisely how ozone abundances will change in a future with diminished chlorofluorocarbon emissions and increased emissions of greenhouse gases remains an important challenge for atmospheric scientists in NOAA and other research centers.

Ozone Research

NOAA Research has, for many years, played a vital role in studying the ozone layer. For instance, at the Chemical Sciences Division of ESRL, researchers are conducting laboratory and field experiments and designing computer models to study this issue. One of the primary missions of ESRL's Global Monitoring Division is to observe and understand the ozone layer through accurate, long-term measurements of ozone, chlorofluorocarbons, greenhouse gases, and solar radiation.

Taking Observations

NOAA researchers build and deploy instruments all over the world to measure ozone, as well as the trace gases and aerosol particles that affect its abundance. They also participate in many field experiments to study and document the processes that control atmospheric ozone. Research scientists take ozone measurements using instruments located on the ground and onboard aircraft, balloons, and satellites. The data from these instruments provide precise measurements that can be used to detect small regional ozone changes over long periods of time, provide global maps of ozone amounts and examine local ozone distributions.

Ozone Depletion

Antarctica

Ozone depletion occurs in many places in the Earth's ozone layer, most severely in the polar regions. NOAA scientists have traveled to Antarctica to study the ozone hole that has been occurring there since the late 1970s. In 1986, soon after the reported discovery of the ozone hole, Aeronomy Lab (now ESRL) scientist Dr. Susan Solomon led a team of 16 scientists, the National Ozone Expedition (NOZE I), to Antarctica. The scientists took measurements of various trace gases and physical properties of the atmosphere. The data, along with additional findings from the NOZE II mission the following year, showed conclusively that human-produced trace gases that contain chlorine and bromine were causing the ozone hole. The Global Monitoring Division of ESRL has monitored the yearly Antarctic ozone hole since 1986 by launching balloon-borne ozonesondes, from the South Pole station and measuring total column ozone from a ground based Dobson spectrophotometer since 1963.

This unique record from the South Pole station clearly shows the annual development of the springtime Antarctic ozone hole over the past two decades. Ozone depletion at the South Pole can also be viewed from another perspective through the images created from data collected by the NASA TOMS satellite, and the NOAA SBUV-2 instruments aboard NOAA satellites. These various ozone measurements provide an important record of the status of the ozone hole. Continued surveillance is necessary in order to verify the expected recovery of the ozone layer.

Arctic Ozone

Significant depletion also occurs in the Arctic ozone layer during the late winter and spring period (January - April). However, the maximum depletion is generally less severe than that observed in the Antarctic, with no large and recurrent ozone hole taking place in the Arctic.

Since the 1980's, scientists at ESRL have been participants in field, theoretical, and laboratory research to demonstrate some of the key processes that contribute to the observed difference between the depletion of ozone in the Arctic and Antarctic. For example, the POLARIS mission in 1997, was designed to study ozone photochemistry in the Arctic during the summertime at middle and high latitudes. And later, the SAGE III Ozone Loss and Validation Experiment (SOLVE) campaign was designed to examine the processes controlling ozone levels at mid- to high latitudes in the Arctic during the winter. The mission also acquired correlative data needed to validate the Stratospheric Aerosol and Gas Experiment (SAGE) III satellite measurements that are used to quantify high-latitude ozone loss. Both these experiments took measurements using the NASA DC-8 and ER-2 aircraft, as well as balloon platforms and ground-based instruments

Atmospheric Models

Another NOAA lab involved in studying stratospheric ozone depletion is the Geophysical Fluid Dynamics Laboratory (GFDL) in Princeton, N.J. GFDL seeks to understand and predict the Earth's climate and weather, including the impact of human activities. Specifically, GFDL conducts leading-edge research (i.e., atmospheric chemistry modeling) on many topics of great practical value, including stratospheric ozone depletion. For example, the GFDL group developed a 3-D atmospheric model tailored to study the interaction of chemistry, dynamics, and radiation in the stratosphere. Their extensive calculations were necessary for evaluating the simpler models used in the policy assessment studies, as well as for understanding the climatic impact of the Antarctic ozone hole.

Ozone-Depleting Substances

Certain industrial processes and consumer products result in the atmospheric emission of ozone-depleting gases. These gases contain chlorine and bromine atoms, which are known to be harmful to the ozone layer. Important examples are the CFCs and hydrochlorofluorocarbons (HCFCs), human-produced gases once used in almost all refrigeration and air conditioning systems. These gases eventually reach the stratosphere, where they are broken apart to release ozone-depleting chlorine atoms. Other examples are the halons,which are used in fire extinguishers and which contain ozone-depleting bromine atoms.

Methyl bromide, is another important area of research for NOAA scientists. Primarily used as an agricultural fumigant, it is also a significant source of bromine to the atmosphere. Although some ozone-depleting gases also are emitted from natural sources, emissions from human activities exceed those from natural sources.

NOAA researchers regularly measure ozone depleting gases in the lower and upper atmosphere and attempt to account for observed changes. As a result of international regulations, ozone-depleting gases are being replaced in human activities with "ozone-friendly" gases that have much reduced potential to deplete ozone. NOAA researchers are also measuring these "substitute" gases as they accumulate in the atmosphere. Observing changes in both old and new gases emitted into the atmosphere allows researchers to improve our understanding of the fate of these gases after release and thereby improve our ability to predict future ozone changes.

Winter Ozone Summaries

The full range of ground-based and satellite-based observations from several NOAA offices are collected together and used to describe the past Arctic or Antarctic winter in the Climate Prediction Center's Winter Ozone Summaries. The contributors include the National Weather Service's Climate Prediction Center (CPC), NOAA Research and the National Environmental Satellite, Data, Information Services (NESDIS). By monitoring and researching stratospheric ozone, as well as the chemical compounds and atmospheric conditions that affect its concentration, NOAA has contributed vital information toward protecting the Earth's stratospheric ozone layer. Perhaps most notable is NOAA's instrumental role in providing ozone data and analysis for the United Nations Environmental Programme and World Meteorological Organization.

Communicating Information on Ozone depletion

The world's population is a stakeholder in decisions that limit the emissions of ozone-depleting gases. In 1987, the international community put in place a treaty known as the Montreal Protocol on Substances that Deplete the Ozone Layer . Since that initial treaty was ratified, periodic assessments and updates have been conducted. The Protocol success has derived in part from these scientific updates on the science and observation of ozone depletion made over the past 15+ years. NOAA researchers from several laboratories have participated in all of these scientific updates and have also been active in preparing outreach documents to communicate the science of ozone depletion to the public

50 Things To Do To Stop Global Warming

Global Warming is a dramatically urgent and serious problem. We don't need to wait for governments to find a solution for this problem: each individual can bring an important help adopting a more responsible lifestyle: starting from little, everyday things. It's the only reasonable way to save our planet, before it is too late.

Top 50 Things To Do To Stop Global Warming

1. Replace a regular incandescent light bulb with a compact fluorescent light bulb (cfl)
   CFLs use 60% less energy than a regular bulb. This simple switch will save about 300 pounds of carbon dioxide a year.
   We recommend you purchase your CFL bulbs at 1000bulbs.com, they have great deals on both screw-in and plug-in light bulbs.
2. Install a programmable thermostat
   Programmable thermostats will automatically lower the heat or air conditioning at night and raise them again in the morning. They can save you $100 a year on your energy bill.
3. Move your thermostat down 2° in winter and up 2° in summer
   Almost half of the energy we use in our homes goes to heating and cooling. You could save about 2,000 pounds of carbon dioxide a year with this simple adjustment.
4. Clean or replace filters on your furnace and air conditioner
   Cleaning a dirty air filter can save 350 pounds of carbon dioxide a year.
5. Choose energy efficient appliances when making new purchases
   Look for the Energy Star label on new appliances to choose the most energy efficient products available.
6. Do not leave appliances on standby
   Use the "on/off" function on the machine itself. A TV set that's switched on for 3 hours a day (the average time Europeans spend watching TV) and in standby mode during the remaining 21 hours uses about 40% of its energy in standby mode.
7. Wrap your water heater in an insulation blanket
   You’ll save 1,000 pounds of carbon dioxide a year with this simple action. You can save another 550 pounds per year by setting the thermostat no higher than 50°C.
8. Move your fridge and freezer
   Placing them next to the cooker or boiler consumes much more energy than if they were standing on their own. For example, if you put them in a hot cellar room where the room temperature is 30-35ºC, energy use is almost double and causes an extra 160kg of CO2 emissions for fridges per year and 320kg for freezers.
9. Defrost old fridges and freezers regularly
   Even better is to replace them with newer models, which all have automatic defrost cycles and are generally up to two times more energy-efficient than their predecessors.
10. Don't let heat escape from your house over a long period
    When airing your house, open the windows for only a few minutes. If you leave a small opening all day long, the energy needed to keep it warm inside during six cold months (10ºC or less outside temperature) would result in almost 1 ton of CO2 emissions.
11. Replace your old single-glazed windows with double-glazing
    This requires a bit of upfront investment, but will halve the energy lost through windows and pay off in the long term. If you go for the best the market has to offer (wooden-framed double-glazed units with low-emission glass and filled with argon gas), you can even save more than 70% of the energy lost.
12. Get a home energy audit
    Many utilities offer free home energy audits to find where your home is poorly insulated or energy inefficient. You can save up to 30% off your energy bill and 1,000 pounds of carbon dioxide a year. Energy Star can help you find an energy specialist.
13. Cover your pots while cooking
    Doing so can save a lot of the energy needed for preparing the dish. Even better are pressure cookers and steamers: they can save around 70%!
14. Use the washing machine or dishwasher only when they are full
    If you need to use it when it is half full, then use the half-load or economy setting. There is also no need to set the temperatures high. Nowadays detergents are so efficient that they get your clothes and dishes clean at low temperatures.
15. Take a shower instead of a bath
    A shower takes up to four times less energy than a bath. To maximize the energy saving, avoid power showers and use low-flow showerheads, which are cheap and provide the same comfort.
16. Use less hot water
    It takes a lot of energy to heat water. You can use less hot water by installing a low flow showerhead (350 pounds of carbon dioxide saved per year) and washing your clothes in cold or warm water (500 pounds saved per year) instead of hot.
17. Use a clothesline instead of a dryer whenever possible
    You can save 700 pounds of carbon dioxide when you air dry your clothes for 6 months out of the year.
18. Insulate and weatherize your home
    Properly insulating your walls and ceilings can save 25% of your home heating bill and 2,000 pounds of carbon dioxide a year. Caulking and weather-stripping can save another 1,700 pounds per year. Energy Efficient has more information on how to better insulate your home.
19. Be sure you’re recycling at home
    You can save 2,400 pounds of carbon dioxide a year by recycling half of the waste your household generates.
20. Recycle your organic waste
    Around 3% of the greenhouse gas emissions through the methane is released by decomposing bio-degradable waste. By recycling organic waste or composting it if you have a garden, you can help eliminate this problem! Just make sure that you compost it properly, so it decomposes with sufficient oxygen, otherwise your compost will cause methane emissions and smell foul.
21. Buy intelligently
    One bottle of 1.5l requires less energy and produces less waste than three bottles of 0.5l. As well, buy recycled paper products: it takes less 70 to 90% less energy to make recycled paper and it prevents the loss of forests worldwide.
22. Choose products that come with little packaging and buy refills when you can
    You will also cut down on waste production and energy use... another help against global warming.
23. Reuse your shopping bag
    When shopping, it saves energy and waste to use a reusable bag instead of accepting a disposable one in each shop. Waste not only discharges CO2 and methane into the atmosphere, it can also pollute the air, groundwater and soil.
24. Reduce waste
    Most products we buy cause greenhouse gas emissions in one or another way, e.g. during production and distribution. By taking your lunch in a reusable lunch box instead of a disposable one, you save the energy needed to produce new lunch boxes.
25. Plant a tree
    A single tree will absorb one ton of carbon dioxide over its lifetime. Shade provided by trees can also reduce your air conditioning bill by 10 to 15%. The Arbor Day Foundation has information on planting and provides trees you can plant with membership.
26. Switch to green power
    In many areas, you can switch to energy generated by clean, renewable sources such as wind and solar. In some of these, you can even get refunds by government if you choose to switch to a clean energy producer, and you can also earn money by selling the energy you produce and don't use for yourself.
27. Buy locally grown and produced foods
    The average meal in the United States travels 1,200 miles from the farm to your plate. Buying locally will save fuel and keep money in your community.
28. Buy fresh foods instead of frozen
    Frozen food uses 10 times more energy to produce.
29. Seek out and support local farmers markets
    They reduce the amount of energy required to grow and transport the food to you by one fifth. Seek farmer’s markets in your area, and go for them.
30. Buy organic foods as much as possible
    Organic soils capture and store carbon dioxide at much higher levels than soils from conventional farms. If we grew all of our corn and soybeans organically, we’d remove 580 billion pounds of carbon dioxide from the atmosphere!
31. Eat less meat
    Methane is the second most significant greenhouse gas and cows are one of the greatest methane emitters. Their grassy diet and multiple stomachs cause them to produce methane, which they exhale with every breath.
32. Reduce the number of miles you drive by walking, biking, carpooling or taking mass transit wherever possible
    Avoiding just 10 miles of driving every week would eliminate about 500 pounds of carbon dioxide emissions a year! Look for transit options in your area.
33. Start a carpool with your coworkers or classmates
    Sharing a ride with someone just 2 days a week will reduce your carbon dioxide emissions by 1,590 pounds a year. eRideShare.com runs a free service connecting north american commuters and travelers.
34. Don't leave an empty roof rack on your car
    This can increase fuel consumption and CO2 emissions by up to 10% due to wind resistance and the extra weight - removing it is a better idea.
35. Keep your car tuned up
    Regular maintenance helps improve fuel efficiency and reduces emissions. When just 1% of car owners properly maintain their cars, nearly a billion pounds of carbon dioxide are kept out of the atmosphere.
36. Drive carefully and do not waste fuel
    You can reduce CO2 emissions by readjusting your driving style. Choose proper gears, do not abuse the gas pedal, use the engine brake instead of the pedal brake when possible and turn off your engine when your vehicle is motionless for more than one minute. By readjusting your driving style you can save money on both fuel and car mantainance.
37. Check your tires weekly to make sure they’re properly inflated
    Proper tire inflation can improve gas mileage by more than 3%. Since every gallon of gasoline saved keeps 20 pounds of carbon dioxide out of the atmosphere, every increase in fuel efficiency makes a difference!
38. When it is time for a new car, choose a more fuel efficient vehicle
    You can save 3,000 pounds of carbon dioxide every year if your new car gets only 3 miles per gallon more than your current one. You can get up to 60 miles per gallon with a hybrid! You can find information on fuel efficiency on FuelEconomy and on GreenCars websites.
39. Try car sharing
    Need a car but don’t want to buy one? Community car sharing organizations provide access to a car and your membership fee covers gas, maintenance and insurance. Many companies – such as Flexcar - offer low emission or hybrid cars too! Also, see ZipCar.
40. Try telecommuting from home
    Telecommuting can help you drastically reduce the number of miles you drive every week. For more information, check out the Telework Coalition.
41. Fly less
    Air travel produces large amounts of emissions so reducing how much you fly by even one or two trips a year can reduce your emissions significantly. You can also offset your air travel carbon emissions by investingin renewable energy projects.
42. Encourage your school or business to reduce emissions
    You can extend your positive influence on global warming well beyond your home by actively encouraging other to take action.
43. Join the virtual march
    The Stop Global Warming Virtual March is a non-political effort to bring people concerned about global warming together in one place.
44. Encourage the switch to renewable energy
    Successfully combating global warming requires a national transition to renewable energy sources such as solar, wind and biomass. These technologies are ready to be deployed more widely but there are regulatory barriers impeding them. U.S. citizens, take action to break down those barriers with
45. Protect and conserve forest worldwide
    Forests play a critical role in global warming: they store carbon. When forests are burned or cut down, their stored carbon is release into the atmosphere - deforestation now accounts for about 20% of carbon dioxide emissions each year. Conservation International has more information on saving forests from global warming.
46. Consider the impact of your investments
    If you invest your money, you should consider the impact that your investments and savings will have on global warming. Check out SocialInvest and Ceres to can learn more about how to ensure your money is being invested in companies, products and projects that address issues related to climate change.
47. Make your city cool
    Cities and states around the country have taken action to stop global warming by passing innovative transportation and energy saving legislation.
48. Tell Congress to act
    The McCain Lieberman Climate Stewardship and Innovation Act would set a firm limit on carbon dioxide emissions and then use free market incentives to lower costs, promote efficiency and spur innovation.
49. Make sure your voice is heard!
    Americans must have a stronger commitment from their government in order to stop global warming and implement solutions and such a commitment won’t come without a dramatic increase in citizen lobbying for new laws with teeth.
50. Share this list!
     Spread this list worldwide and help people doing their part: the more people you will manage to enlighten, the greater YOUR help to save the planet will be (but please take action on first person too)!
