Major Progress In CO2 And Global Warming Reduction

At least in America, CO2 emissions have dropped dramatically. The energy sector, the largest producer of CO2, is already back at early 1990s levels of emissions and the traditionally worst offender, coal, is at early 1980s levels. CO2 is the primary greenhouse gas emitted by human activity. A simple way to measure climate sensitivity is to calculate how much the mean air temperature will rise if we were to double the level of overall CO2 emissions compared to the world's pre-industrialized level around the year 1750. If we continue to emit greenhouse gases at our current rate, estimates are that we risk doubling that atmospheric CO2 level in roughly 2050. read more
