The analysis of data shows that during last century our planet the Earth was warmed up on one degree above an average indicators .
Scientists presumption of fact – in the next 50 years the temperature will rise for 3-5 degrees and that will lead to heavy consequences both for the Earth, and for people , flora and fauna.
Here are some more figures and the facts confirming process of global warming on the Earth:
1). The global temperature has increased on 0,7°С for last 300 years when change of a climate was observed.
The increase of 0,5°С has occurred in 20 century, basically during 1910 -1940 and 1976 – 2007.
2). 4 of 5 warmest years were marked after 1990.
3). Last decade of 20th century became the warmest, and 1998 the warmest year for the period of supervision since 1861.
4). Period of time January – June 2002 became the warmest beginning of year in northern hemisphere.
5). The general number of cold days (when average temperature were below 0°С) has decreased from 15-20 ( in a year ) in the 20th century to about nearby 10 days in a 2006 & 2007.
6). During 1995 was counted over the greatest number of hot days in a year ( for 225 years of daily supervision ) - 26 days with temperature above 20°С.
7). The sea level raises everywhere, the Arctic ice became thinner , sedimentation become more intensively in some parts of the world.
On the average - the sea level has raised from 0,1 up to 0,2 m in last 100 years.
8). The area borrowed by a snow cover in northern hemisphere has decreased since 1960 for 10 %.
9). Glaciers in mountains in non polar areas have considerably decreased during 20th century .
10). In many regions of northern hemisphere in the moderate and high breadths, there is an increase in total of sediments, speed of sedimentation makes 0,5-1 % per a decade.
11). In the same regions of the world there was an increase in frequency of strong rains, in about 2-4 % for a decade.
12). Repeatability and intensity of droughts has increased In Asia and Africa in last decades.
