Since 1850, burning of fossil fuels, coal, oil and natural gas has increased 100 times to produce energy as the world has industrialized to serve the world's more than 6 billion and growing population.
John OlverThe scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must be attributed to burning those fossil fuels to produce the energy that drives industrialization.
John OlverAs this body of knowledge has evolved, a much more critical job for researchers and scientists has evolved into explaining and educating policy makers and the public to the risks of global warming and the possible consequences of action or of no action.
