I've been growing every possible kind of plant all my life, and I'm very familiar with the wisdom of plant growers--and I agree with them.
That has almost nothing to do with our global warming crisis or the need for countermeasures.
I've already cited NASA, and they're easy enough to find. Here's another major resource:
This page is based on a brief synopsis of the 2007 Fourth Assessment Report (AR4) by the Intergovernmental Panel on Climate Change (IPCC), as well as NCEI's own data resources. It was prepared by David Easterling and Tom Karl, National Centers for Environmental Information, Asheville, N.C. 28801.
One of the most vigorously debated topics on Earth is the issue of climate change, and the National Environmental Satellite, Data, and Information Service (NESDIS) data centers are central to answering some of the most pressing global change questions that remain unresolved. The National Centers for Environmental Information contains the instrumental and paleoclimatic records that can precisely define the nature of climatic fluctuations at time scales of a century and longer. Among the diverse kinds of data platforms whose data contribute to NCEI's resources are: Ships, buoys, weather stations, weather balloons, satellites, radar and many climate proxy records such as tree rings and ice cores. The National Oceanographic Data Center contains the subsurface ocean data which reveal the ways that heat is distributed and redistributed over the planet. Knowing how these systems are changing and how they have changed in the past is crucial to understanding how they will change in the future. And, for climate information that extends from hundreds to thousands of years, paleoclimatology data, also available from the National Centers for Environmental Information, helps to provide longer term perspectives.
Internationally, the Intergovernmental Panel on Climate Change (IPCC), under the auspices of the United Nations (UN), World Meteorological Organization (WMO), and the United Nations Environment Program (UNEP), is the most senior and authoritative body providing scientific advice to global policy makers. The IPCC met in full session in 1990, 1995, 2001 and in 2007. They address issues such as the buildup of greenhouse gases, evidence, attribution, and prediction of climate change, impacts of climate change, and policy options.
Listed below is information based upon common questions addressed to climate scientists (based on IPCC reports and other research) in common, understandable language. This list will be periodically updated, as new scientific evidence comes to light.
