Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level
Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations
Here are the projections for future surface temperatures. The worst case scenario (A2) is the one in red. 4 degrees and upwards of temperature increase for almost all of India. Summers are horrible enough now. Imagine the future!
