It doesn't seem possible. The entire Earth is getting warmer because of human
activity? Many scientists say it's true.
The warming of the Earth is the subject of intense concern of many scientists,
policy-makers, and citizens. Participants in the debate are often ignorant of the
facts and the scientific principles underlying global warming. This is
understandable. Global warming is an incredibly complex subject and many
important facts are not widely known. Planetforlife will try to explain the
science of global warming with objectivity and detachment.
The bulk of the information presented on this website comes from three sources.
In 1988 the
United Nations established the IPCC (Intergovernmental Panel on Climate Change).
The IPCC is fundamentally a scientific body although the UN is a political
institution. Leading scientists from around the world make up the IPCC. In 2001,
the IPCC published a report called Climate Change 2001: The Scientific Basis.
At 900 pages, it is rather ponderous but there are three summaries; one is
graphical, one is technical and one is for policymakers. You can see the report, the
summaries, and related reports at:
The U.S. Department of State published the US Climate
Action Report in May of 2002. This report is the third communication to the United
Nations Framework Convention on Climate Change. The report is hosted on the
EPA's (Environmental Protection Agency) website. At 11 megabytes, this 269 page
PDF format report is large and exhaustive. But it is well done and there are many
pictures. You can see the report or an overview HERE
Planetforlife also has a copy of the full report.

satelites. NASA also has expertise in meteorology and climatology. In June of
2003, NASA/Goddard Institute for Space Studies published a very readable
presentation called Can We Defuse the Global Warming Time Bomb? by James
A slightly revised version of the report appears in the March 2004 issue of Scientific

Dr. Hansen has testified before the U.S. Senate Committee on Commerce, Science and Transportation.
These sources represent the mainstream of scientific thought on the subject of global
Global warming is such an all encompassing problem that it is necessary to
deal with all its aspects, and that includes the politics. Politicians, when
formulating policy, will need inputs from many disciplines, including science.
Unfortunately, global warming has become a political issue. It is ominous that
politicians, at least in the U.S., are attempting to influence science.
Planetforlife will try to keep the science and the politics separate.
