Global warming and climate change refers to the increase observed in the last century the average temperature of the Earth’s climate system and its related effects. Multiple lines of evidence demonstrate that the climate system is warming. Over 90% of the additional energy gained since 1970 has been stored in the climate system has gone into the oceans; the remaining ice has melted and heated continents and atmosphere. Many of the changes since the 1950s are unprecedented for decades to millennia.
What’s going on?
According to experts in the field, as a result of record global average that reached the levels of carbon dioxide (CO2) in early 2015 (400 ppm), and apparently will continue in the coming years, It provides for a period of alert.
Less than one degree? Is it a lot?
In the last 100 years the average global temperature has risen by 0.86 ° C. When compared with that in the Ice Age the temperature was four degrees less than the current (15 ° C), less than one degree may seem an insignificant figure. However, if the temperature rises by more than 2 degrees in the coming years, we may face difficult changes to bear.
