After all, the burning of fossil fuels to generate energy releases large quantities of carbon dioxide into the atmosphere. The CO2 level has been increasing steadily since the beginning of the industrial revolution and is now 35 percent higher than it was 200 years ago. Also, we know from direct measurements that CO2 is a “ greenhouse gas” which strongly absorbs infrared (heat) radiation. So the idea that burning fossil fuels causes an enhanced “greenhouse effect” needs to be taken seriously. But in seeking to understand recent warming, we also have to consider the natural factors that have regularly warmed the climate prior to the industrial revolution and, indeed, prior to any human presence on the earth. After all, the geological record shows a... Źródło: poloniao2.fora.pl/a/a,62.html Temat: Szczepionki ...impact.” Population growth is one of the most politically sensitive environmental problems. The issues it raises, including religion, culture and immigration policy, have proved too toxic for most green groups. However, Porritt is winning scientific backing. Professor Chris Rapley, director of the Science Museum, will use the OPT conference, to be held at the Royal Statistical Society, to warn that population growth could help derail attempts to cut greenhouse gas emissions. Rapley, who formerly ran the British Antarctic Survey, said humanity was emitting the equivalent of 50 billion tons of CO2 into the atmosphere each year. “We have to cut this by 80%, and population growth is going to make that much harder,” he said. Such views on population have split the green movement. George Monbiot, a prominent writer on green issues, has criticised population campaigners, arguing that...

In 2007, for example, about 300 people died and 800,000 others were affected. OCHA noted today that climate change is driving these natural disasters, with the region possibly paying a high human cost due to global warming. Ahead of December’s UN climate change conference in Copenhagen, Denmark, when nations are aiming to reach agreement on slashing greenhouse gas emissions, West African nations have been holding frequent high-level and expert meetings on the issue http://www.afrol.com/articles/34107 Źródło: poloniao2.fora.pl/a/a,359.html Temat: Dido z Buena Vista Social Club Dido collaborates with Buena Vista for charity album The current number 1 best-selling Latin album on iTunes is 'Rhythms del Mundo Cuba', which features a host of artists collaborating with members of the Buena Vista Social Club. They include Dido, who sings on a Latin version of 'One Step Too Far'. The album is a fundraiser for Artists Project Earth, which aims to achieve permanent reductions in greenhouse gas emissions; reducing them to levels which can be sustained, and which result in no further degradation of ecological systems and human livelihood. Said Dido of the project: "The incredibly obvious and real signs of global warming are all around us now. This is not an inevitable or irreversible situation yet. There is still time for each one of us to make the right choices and change the outcome. But time is definitely running out. This is not...

Thirty years on, my views have changed, and the rest of the environmental movement needs to update its views, too, because nuclear energy may just be the energy source that can save our planet from another possible disaster: catastrophic climate change. Look at it this way: More than 600 coal-fired electric plants in the United States produce 36 percent of U.S. emissions -- or nearly 10 percent of global emissions -- of CO2, the primary greenhouse gas responsible for climate change. Nuclear energy is the only large-scale, cost-effective energy source that can reduce these emissions while continuing to satisfy a growing demand for power. And these days it can do so safely. I say that guardedly, of course, just days after Iranian President Mahmoud Ahmadinejad announced that his country had enriched uranium. "The nuclear technology is only for the purpose of peace and nothing...
