1.Historic vote on global warming

A U.S. Senate committee is scheduled for an historic vote on a global warming bill this week, perhaps as early as Wednesday. Environmental groups are planning a flurry of press conferences tomorrow (12/4/2007) to try to influence the vote.

2.Film to help tackle global warming

A company is hoping to help tackle the issue of global warming with an environmentally-friendly film release.
Big River Man is a feature-length documentary about Martin Strel, who campaigns for the environment by swimming in polluted stretches of the Mississippi and Amazon rivers.
Film distributors have pledged to avoid chemical processing, petrol consumption and waste by-productions involved in Big River Man's distribution process.
The film will be delivered from the US on the internet, transported to cinemas using electric transport or through a new digital delivery process.
When the film is released on DVD, it will come in fully biodegradable packaging.

3.WWF calls on developed countries to take lead in emission reductions

A press release of the WWF during the two-week U.N. climate change conference in Bali, Indonesia, said Tuesday that financial resources will have to be provided by the international community to help developing countries adapt to the damaging effects of climate change.
"The devastating impacts of climate change reach across the globe, but in the near-term those most at risk, and least responsible, are developing countries," said Hans Verolme, director of the WWF's Global Climate Change Program.

4.Global warming is pushing edges of tropics towards poles: study

The greenhouse effect is causing Earth's zone of tropical climate to creep towards the poles, according to a study whose release on Sunday coincided with the eve of a major UN conference on climate change.
The poleward expansion of the tropics will have far-reaching impacts, notably in intensifying water scarcity in the Mediterranean and the US "Sun belt" as well as southern Africa and southern Australia, it warns.

5.Earth not only planet that's been warming

Two big non-supporting facts are that even though manmade CO2 production has increased continuously for over 200 years, the overall Earth's temperature dropped from 1940 to 1975. And, more recently, not only has the Earth been warming up, but so have other planets like Mars, which doesn't receive any of our manmade CO2.

what you can do about global warming?

Take Personal Action
You can reduce your personal contribution to global warming and set an example for others by using less gasoline, natural gas, oil, and electricity in your daily life. Your choices about energy and transportation are especially crucial.
The next time you buy a car, choose one that is highly fuel efficient. Your choice of vehicle is probably your single most important environmental decision: for every single gallon of gasoline burned, 20 pounds of carbon dioxide go into the atmosphere.
Instead of driving alone in your car, join a carpool, take mass transit, walk, or ride a bike -- anything that reduces the amount of gasoline you burn.
The next time you buy an appliance, purchase a highly efficient model. You can tell by looking for the Energy Star, awarded by the Environmental Protection Agency.
Ask your local electric or gas utility to perform an energy audit of your house or apartment. Then put the recommendations into practice.
Develop a plan to reduce daily electricity use around your home. Ask each member of your household to take responsibility for a different electricity-saving action.

Is global warming caused by green house gases or by the sun?

Most scientists believe that the current global warming is caused by man-made emissions of greenhouse gases and that the most important of these gases is Carbon Dioxide or CO2.They also believe that the Sun's influence for this warming is very small. We now know that the irradiance or "heat transfer" from the Sun to the Earth has varied relative little during recent decades. Therefore the conclusion that most scientists have done is that the resent warming must be man-made, this is because they haven't found any other reasonable explanation.However what we know over how much a specific increase of CO2 has on global temperature is poor. The reason in that the knowledge of how greenhouse gases affect cloud formation is mostly down to speculations. Cloud formation physics is quite a complicated process to explain with many factors.So, rather than having a solid theoretical and measured basis for how much man-made greenhouse gases affect the climate, the made estimation is mostly down to deduction.They argue: We know how much the temperature has increased so therefore we can calculate how much a specific increase in greenhouse gases will increase the global temperature in the future. We have done this through deduction as we already have attributed the known increase to be greenhouse driven.However scientists who study the Sun have long noted similarities between solar activity and terrestrial weather patterns.Also the weather changes the last century is not something unique. Given the relative small changes in the observed irradiance "heat emitted from the Sun", those changes in temperature during past centuries are hard to explain if you don't include some other types of influence from the Sun.It was not until the Danish scientist Henrik Svensmark suggested that cosmic radiation could influence cloud cover that a plausible explains for this apparent correlation was given.Here is this theory!When the Sun is very active, as it is now, the solar wind and the solar magnetic field are both strong. This in turn shields the Earth from high energy particles coming from the cosmos, usually from particles which were once created in supernova explosions. This affects low cloud cover formation as the radiation create ions which seeds cloud forming water droplets. During times when there are many high energy particles reaching low altitudes there are more low cloud cover and the Earth cools. When there are few high energy particles penetrating to low altitudes then less clouds form and the Earth warms.Usually clouds higher up in the atmosphere are almost always ionized from both low and high energy particles because both those types of particles penetrate high altitudes at all time.The created variations are only in the low altitude cloud cover which is affected by very high energy cosmic particles.Recently an experiment called SKY (Cloud in Danish) was made by Svensmark which conclusively confirmed this cloud forming mechanism experimentally and that this type of cosmic ionization has an important seed effect on clouds. Links between low cloud cover variations and high energy particles intensity have also now been confirmed by satellite studies.

global warming:the heat is on

Unless we act now, our
children will inherit a hotter world, dirtier air and water, more severe floods
and droughts, and more wildfires .

May there only be
peaceful and cheerful Earth Days to come for our beautiful Spaceship Earth as it
continues to spin and circle in frigid space with its warm and fragile cargo of
animate life.
