A recent White Paper issued by the Federal Government pointed out that the climatic changes that are caused by greenhouse gases are affecting the United States at an increasing rate. However, the study also showed that global warming affects North America in an uneven manner.

At a recent conference about climatic change patterns in the United States, several researchers brought up interesting facts about the effects of global warming in North America. The administrator of the National Oceanic and Atmospheric Administration, William J. Brennan, stated that the main cause of the recent years’ climatic changes is due to the “energy sources we are using.” On the other hand, Martin Hoerling, of NOAA's Earth System Research Laboratory, said that the changes do not affect the entire country, as researches did not track any noticeable climatic change in a large area between the Rocky Mountains and the Appalachians.

The government’s report pointed out that the average surface temperatures in the U.S. have raised by almost 1 degree Celsius in the last 3 decades. Furthermore, the International Panel on Climate Change, which did a complex research on climatic changes across the world, concluded that global warming is an undeniable phenomenon and that it has already started to affect our planet.

Recently, NOOA’s National Climatic Data Centre issued a report that has worryingly results. The study showed that the temperature in the mainland U.S. in November was 1.1 degrees Celsius higher than the average. Furthermore, the report showed that this year’s precipitations were 0.5 centimeters lower than the 1901-2000 average and that the average January-November temperatures increased by 0.6 degrees since 1895.
