Climate change global temperature, increase

Finally, increases in the intensity or variability of weather are considered another form of indirect evidence reflecting whether Earth is currently undergoing human-driven climate change. Predictions of increased incidence of extreme temperatures, tornadoes, thunderstorms, dust storms and fire-promoting weather have been drawn from basic global climate change theoiy. However, evidence has not so far borne out these predictions on a global scale. The IPCC concludes ... 

Secondly, rising concerns about climate change prescribe to reduce greenhouse gas emissions so as to not exceed a concentration of 450 ppm of C02 in the atmosphere which is believed to correspond to a global temperature increase of 2°C. How to curb C02 emissions that currently grow at a rate of 2%/year to the point of making them decrease from the mid-2010s onwards ... 

Over the last centuries, climate change has been raised as a very important issue all over the world. The change in climate results from an increase in the earth s average atmospheric temperature, which is usually referred to as global warming. It may be due to both natural and human causes, especially greenhouse gas (GHG) emissions.
