Coal definitely creates less net warming in the short-term because of aerosols. Aerosols pollution emitted from coal is basically smog. The sulfates in smog rom burning fossil fuels are global cooling pollutants. Coal has far more sulfate pollution than oil and oil has far more sulfates than natural gas. Though natural gas emits less CO2…
When will we completely leave our old climate? When will our new climate be 100 percent different than our old? When will the normal temperature in the our new climate be warmer than anything in our old climate? It’s called Climate Departure and it is coming soon to a planet near you. On the path…
We have more acronyms for your increased state of general confusion. The AR5 is coming up (Assessment Report 5) to be relapsed by the IPCC in 2013 (Intergovernmental Panel on Climate Change.) This generation’s report will look at newly created scenarios that more appropriately simulate atmospheric physics than the current scenarios. Scientists are leaving behind…
To limit warming to 2 degrees C by 2050, the world must limit greenhouse gas emissions to 275 gigatons between 2000 and 2050. Considering that we have already emitted nearly one third of this 275 gigatons in nine years, this is going to be "extremely difficult" says the author of the report (Meinhausen). The research…
From the Guardian, the UKs third largest daily, the Sunday edition of the Guardian is called the Observer and is the world’s oldest Sunday newspaper. (March 30, 2009) Lord Stern’s background can be found here. The following quote references Lord Sterns report in October 2006: "When it came out, people thought I’d over- egged the…
Preliminary release of information from Copenhagen shows that with the best case scenario of CO2 emissions reductions, where CO2 emission decline by 3% per year by 2015 (this is a very aggressive reduction rate), there is still a 50% chance that the earth will warm 3.6 to 5 degrees F by 2100. A 3.6 degree…
Among the things Hansen says must be done – moratorium on all coal fired power plants that do not sequester 100% of CO2, A complete analysis of the polar ice caps, a carbon tax instead of cap and trade. Hansen says: "Before the end of Obama’s first term, we will be seeing new record temperatures….
The American Association for the Advancement of Science (AAAS) is the world’s largest general scientific society, with nearly 120,000 individual and institutional members. They publish one of the top academic journals in the world: Science. Prof James McCarthy, president of the AAAS, stated on the eve of the annual meeting of the American Association for…
