However, claims based on «eyeballing» and similar offered here in the thread by Mr. Coal - Magazine Editor, who is probably going to write his PhD thesis soon where he refutes global warming using «eyeballing», and by other «skeptics» are not a scientifically valid approach to provide evidence for the assertion of the «stopped» global warming.

In a sharp change from its cautious approach in the past, the National Academy of Sciences on Wednesday called for taxes on carbon emissions, a cap - and - trade program for such emissions or some other strong action to curb runaway global warming.Such actions, which would increase the cost of using coal and petroleum — at least in the immediate future — are necessary because «climate change is occurring, the Earth is warming... concentrations of carbon dioxide are increasing, and there are very clear fingerprints that link [those effects] to humans,» said Pamela A. Matson of Stanford University, who chaired one of five panels organized by the academy at the request of Congress to look at the science of climate change and how the nation should respond.

Given the inappropriate use of the data sources, the Global Carbon Project estimation of global emissions and contribution from China, especially from its coal consumption, may be misleGlobal Carbon Project estimation of global emissions and contribution from China, especially from its coal consumption, may be misleglobal emissions and contribution from China, especially from its coal consumption, may be misleading.

The study notes that current global reserves of coal, oil and gas equate to the release of nearly 3 trillion tonnes of CO2 when used and based on this draws the conclusion that two thirds of this can not be consumed if a global budget were in place that limits emissions to 1.1 trillion tonnes of CO2 for the period 2011 to 2050.
