For those of you living in caves for the last few decades and decided
to come out and see what this Intertube thing is all about, Global
Climate change is the widely accepted theory that mankind has been
screwing itself very badly since the beginnings of the industrial
revolution and in less than a hundred years at least part of the
consequences will be felt in the form of drastic climate shifts, a rise
in sea levels and general bad feelings. For those who still doubt
the existence and/or cause of GCC, please go
here before reading the rest. The bad news is that it's
coming, it's going to be bad, and the longer we go without doing
anything the harder it will be to reverse or even stop it. The good news: We will probably lose Florida completely.
Related to Global Climate Change is the rapid decline of the production of fossile fuels. Regardless of the need to reduce emissions for the sake of the environment, scarcity of oil and coal will force us to reduce emissions anyway, albeit slower than experts say is needed. In order to maintain our economies: transportation and energy production in the face of these two threats, we must find alternate fuels, and we must find them fast. Gasoline prices are already at record levels, and seem set to go nowhere but up from now on until the last drop is squeezed out of the planets crust. The documents and the excerps below seek to impart the details of Global Climate Change and the state of the Earths climate. The News forum off the main page will keep track of progress on alternate fuels and the curbing emissions. |
| Human activity accounts for 26.4 billion
tons of CO2 per year (UN IPCC) Tipping point: 350-450 parts per million of atmospheric CO2 (Bill McKibben, James Hansen, Paul Brown) will warm the earth by 2 degrees C above pre-industrial levels, which is supposed to be enough to create a feedback loop in the atmosphere to trigger runaway warming, which will, in turn produce another ice age when the Atlantic conveyor shuts down. We're already at 375 ppm and heading to +1.5 degrees C in the next 20 years. Coal 67% more CO2 than natural gas. Accounts for 40% of US greenhouse gas emissions Clean Coal Does not reduce methane emissions Methane Accounts for 9% of US greenhouse gas emissions ![]() This chart comes from the NASA Goddard Institute |
What about Methane? There’s a lot more CO2 in the air than methane! CO2 makes up roughly about 0.04% of the Earth’s atmosphere by volume. Methane? 0.0002%. Methane is in fact a more efficient greenhouse gas than CO2, but there’s so much less of it that the overall effect is much lower. Methane’s contribution to the greenhouse effect is only about half or less that of carbon dioxide. |
