“Warming of the global environment could lead to major disputes that the Security Council might help resolve” British U.N. representative Crispin Tickell. “If global warming does take place and…environmental degradation follows, there will be great risks of dispute between states about food…the use of productive land…the supply of fresh water…people who are maybe fleeing from particular environmental problems,” he said. “And all these problems... more
Global Change Research Program, under which a number of federal agencies cooperate on a major study of the Earth’s climate and global warming. “Evidence is increasing on the scientific table that change is occurring,” said Robert Corell, Assistant Director of Geological Science at the National Science Foundation (NSF), one of the agencies which participates in the program. Other agencies besides NSF which will be working on the program include the U.S. Geological Survey (USGS),... more
While carbon dioxide receives most attention in discussions of global warming, methane, another greenhouse gas, is also building up rapidly in the atmosphere as a result of various human activities. USEFUL FACTS: Sources of methane: rice paddies, termites, coal mines, land fills, and digestive tracts of animals. Estimated shares: Tundra, bogs, swamps 26% Rice 20 Livestock 15 Burning of vegetation ... more
The global warming is due to increased carbon dioxide in the atmosphere due to (among other things) increased burning of fossil fuels and the depletion of the plant life (rainforests and phytoplankton) that convert that carbon dioxide back into free oxygen and plant material. So what do CFC gasses have to do with global warming? CFCs absorb infra-red radiation in different bands than CO2. The atmosphere is more nearly opaque in the bands absorbed by CO2 than it is in the bands absorbed by CFCs. ... more
For decades the prevailing assumption has been that a fossil-fuel-based economy would be constrained by oil, gas and coal depletion. Logical enough. But global warming has turned that paradigm on its head: It now appears that the atmosphere’s ability to assimilate fossil-fuel wastes will be the limiting factor. The question is no longer how much oil, gas and coal we have, but how much we can afford to burn. A number of institutions and organizations, including Sweden’s Beijer Institute,... more
A friend recently told me of an interesting study done by two geologists. The study was an explanation of why none of the predicted sea coast flooding has occured yet. This flooding is predicated by those who forsee global warming due to the CO2 and halogen-organics that have been added to the atmosphere since the start of the Industrial Revolution. The geologists claim that the water added from melting ice has about the same volume as the water that has been impounded in reservoirs by dams et.... more
There are many opportunities for slowing global warming. However, there are many reasons to believe that global warming is ultimately inevitable. Carbon dioxide, once produced, stays in the atmosphere for thousands of years. It takes a long time for the atmosphere to come into equilibrium with the ocean, and even longer for dissolved CO2 to be deposited as carbonate rock. Cutting CO2 production in half will not prevent significant global warming, just delay it. China currently produces 10% of... more
I recently went to a debate at a local American Meteorological Society meeting between two climatologists about the greenhouse effect. Among the interesting points that came out and were agreed on by both the “pro” and “con” are: The physics of CO2 trapping heat are well understood and not a matter of disagreement. The CO2 content of the atmosphere has increased about 20% over the last 100 years. The global temperature has not increased in a statistically significant amount. ... more
Global Warming Rising Sea The real danger of global warming is not that there will be atypical freezes during some years. It’s that the polar and arctic areas are getting warming, which released more water, which affects global sea levels, which affects the amound of land which can sequester CO2 to ameliorate global warming. Once the cycle starts, the solution will be much more difficult. The majority of the 1-2mm/year increase in sea level is attributable to thermal expansion, rather than... more
Global Warming Happening! Is everyone enjoying being a prisoner of A/C this summer? How’s that electric bill to run the bugger? Meanwhile glaciers melt worldwide, some in Europe exposing to the light of day hidden bunkers from WW v.1.0 or dead soldiers of the same genre. And of course, a 5,000 year old body was exposed the same way in 1991, old news indeed. If you look at fossil fuel use history and CO2 level rise, you notice a pattern. The two reasonably well match. Even funnier is how the... more
Help Stop Global Warming
Global warming could do more than just melt polar ice. It could change our maps, and displace people from cities and tropical islands.
