Global warming being caused by human activities: climate change experts say

The record-breaking hottest years in the past one and a half decade are extremely unlikely to have occurred without the global warming caused by human activities, according to new calculations by climate change scientists.

Thirteen of the fifteen hottest years recorded in the last 150 years occurred between 2000 and 2015, and the researchers determined that merely there is 0.01 per cent chance of its happening because of natural variations in Earth’s climate. The year of 2015 smashed all earlier records in terms of heating.

Prof. Stefan Rahmstorf, a climate change expert at Germany’s Potsdam Institute for Climate Impact Research, “Natural climate variations just can’t explain the observed recent global heat records, but manmade global warming can. The risk of heat extremes has been multiplied due to our interference with the Earth system, as our analysis shows.”

Rahmstorf warned that the record heat brought significant impacts. For instance, it caused unprecedented local heat waves across the globe that resulted in loss of life through aggravated droughts and wildfires.

Petteri Taalas, secretary-general for the U.N. World Meteorological Organization (WMO), confirmed on Monday that the global average temperature of Earth’s surface shattered all previous records in 2015. The average globe temperature has reached the threshold of 1 degree Celsius above pre-industrial temperatures for the first time in recorded history.
