Fossil Fuel CO2 Emissions Trends — 1990, 2000, 2008

Overall, global CO2 emissions from fossil fuels increased 29% between 2000 and 2008 and 41% from 1990-2008, and the current concentration of CO2 in the atmosphere is now at its highest in at least 2 million years, according to a new study in the journal Nature Geoscience.

The new report published this week by an international team of researchers who are part of the “Global Carbon Project” shows emissions trends through 2008 (including changes in emissions causes and in the amount of emissions remaining in the atmosphere) and brings up some major questions for the future as well.

40% of Amazon Will Disappear Despite Climate Change Efforts

Fourty percent or more of the Amazon rainforest will be “decimated” by the middle of the next century even if we cut all CO2 emissions by 2050, said the UK Met Office. The finding was presented this past month in Copenhagen, which is preparing to host the UN Climate Change Conference in December.

In this satellite image of deforestation in Brazil, tropical rainforest appears bright red, while pale red and brown areas represent cleared land. Black and gray areas have probably been recently burned.

Thank Global Warming for New Tree Growth

Quicker-melting snow cover will allow forests to encroach on meadows and, ironically, eventually aid in cooling the planet.

Regina Rochefort, a National Park Service science adviser at Mount Rainier, said the meadows surrounding the famous peak have been shrinking because of less snowfall and shorter periods of snow cover. In the past, the snow has restricted new tree growth with freezing temperatures a limited water supply.

So you’re probably thinking this is great news—after all, more trees will store more carbon, right? But according to a study performed last year, the good news is more so that less snow will mean more water for the trees, which will dramatically increase the forest’s overall cooling impact.
