Global temperatures have seemingly plateaued in the past 10 years. Those dubious about climate science or wary of the social implications of carbon regulations have seized on this point to argue that fears of global warming have been overblown. However, [...]

Scientists are increasingly finding that black carbon aerosols in the atmosphere and their deposition on snow and ice-covered areas are having more of a warming effect than earlier thought.

Human emissions of carbon dioxide (CO2) are the primary factor contributing to the warming of the Earth’s surface over the past half-century. However, for the past few years global temperatures have been stagnant or slightly decreasing even as atmospheric CO2 [...]

In reporting on climate change, the carbon, carbon dioxide (CO2), greenhouse gases, radiative forcing, and CO2-equivilent (CO2-eq) are often used almost interchangeably to refer to the human contribution to recent warming.

It is difficult these days to find an article about climate science without some mention of tipping points and the risk of abrupt climate change. Some prominent climate scientists and policy proponents have warned ominously that we have only a [...]
