Temperatures are most likely warmer now than they have been at any time in the past 400 years. They are probably (slightly less certain) warmer than in the past 1200 years, perhaps (less certain) warmer than in the past 12,000 years, and new evidence suggests that we are approaching the warmest temperatures this planet has seen in a million years.

Yet there is no scientific consensus that global warming is a problem or that humans are its cause. Even if current predictions of warming are correct, delaying drastic government actions by up to 25 years will make little difference in global temperature 100 years from now. Proposed treaty restrictions would do little environmental good and great economic harm. By contrast, putting off action until we have more evidence of human-caused global warming and better technology to mitigate it is both environmentally and economically sound.

The Earth's rapid warming has pushed temperatures to their hottest level in nearly 12,000 years – and a hair’s breadth away from a million-year peak – according to a NASA study.

Whatever climate scientists may currently disagree about (and good scientists are always disagreeing about something) virtually all of them have long since agreed that human activity -- burning fossil fuels -- has been making the global temperature go up. And now they have two very sobering, visual ways to explain how.

Vast majority of scientists believe global warming is a fact. Rare exceptions are some USA scientists but since we know USA refuse to sign Kyoto protocol, althrought they are accounted for 25 % of world CO2 emissons, their opinion could be biased. Average global temperature is rising there is no doubt about that. You can see that in the next chart.

No matter where they look, scientists are finding that global warming is already killing species—and at a much faster rate than had originally been predicted. "What surprises me most is that it has happened so soon," said biologist Camille Parmesan of the University of Texas, Austin, lead author of a new study of global warming's effects.

Global warming skepticism: There have been a number of recent articles raising doubts about the mainstream view of global warming. Here are a couple of the more interesting ones from the British press: "Kyoto is pointless, say 60 leading scientists" (Daily Telegraph 4/9/2006) "There IS a problem with global warming... it stopped in 1998" (Daily Telegraph 4/9/2006)

Humans are causing the global warming phenomenon which could spark more droughts, heatwaves and rising seas, a major report has said. The stark warning comes from the United Nations climate panel and is likely to put pressure on governments and companies to to curb greenhouse gases.

Carbon dioxide is not a pollutant. It is tasteless, colorless, nontoxic to humans at concentrations up to 13 times present levels and is essential to life. Plants breathe CO2, and as they grow and reproduce they exhale oxygen, making the earth habitable for humans. Instead of a disaster, the expected doubling of CO2 due to human activities will produce a number of benefits over the next century.

Green investing is no longer a new phenomenon, but this is something different. This is not designed to spur companies into protecting the environment – this is a growing field of research and investment advice that attempts to peer into the future and determine who will win and who will lose as a result of global warming.

The finding shows that as temperatures warm, the growth of single-celled ocean plants called phytoplankton slows at Earth's mid and low latitudes. The plants' growth increases when the climate cools.
12
Global atmospheric concentrations of carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values determined from ice cores spanning many thousands of years.

The world is already committed to centuries of warming, shifting weather patterns and rising seas from the atmospheric buildup of gases that trap heat, but the warming can be substantially blunted by prompt action, an international network of climate experts said today.
14
Global climate change is "very likely" to have a human cause, an influential group of scientists has concluded. The Intergovernmental Panel on Climate Change (IPCC) said temperatures were probably going to increase by 1.8-4C (3.2-7.2F) by the end of the century.
15
It was a U.S. government scientist who helped push through the strong language in the upcoming international report on global warming. But that doesn't signal a change in President Bush's policy about greenhouse gas emissions.
16
Scientists and economists have been offered $10,000 each by a lobby group funded by one of the world's largest oil companies to undermine a major climate change report due to be published today.

MIT’s Richard Lindzen called fears of manmade global warming ‘silly" and debated PBS’s Bill Nye "The Science Guy" and the controversial Weather Channel host Heidi Cullen on last night’s Larry King Live. Lindzen corrected several of Nye's claims regarding climate science. "We are simply saying that if you wish to issue scare remarks, you should make them accurate, according to the science," Lindzen told Nye.
