Humanity is major culprit behind global warming and climate change shows statistics

Scientists from the World Meteorological Organization (WMO) claim global temperatures hit a record high, making 2015 the hottest year in history. The researchers argue that the extreme weather conditions such as El Nino, drought, rising sea levels and the extreme heat experienced in 2015 were mostly as a result of human activities. They are the result of greenhouse gasses released by burning fossil fuels.

Scientists claim that 2015 was the hottest year recorded since the 19th century. They also stated that the high temperatures and extreme weather conditions would not have occurred it not for human influence on the environment.

Scientists had predicted that the possibility of record warm years would occur between the year 2000 and 2014. The odds fell within one in 770 and one in 10,000 on a random basis with no human influence.

Speaking to Reuters, Professor Michael Mann from the Pennsylvania State University revealed that the computer simulations used by the scientists indicate that the odds have escalated to one in 1,250 and one in 13,000 including the year 2015.

Professor Mann also stated that the climatic changes are no longer minor and are mostly caused by human activities. Signs of record warmth were first seen in the year 1998 but the record high years have been 2011 to 2015.

In 2015, the temperatures rose above the 1953-1999 long term internationally agreed average by 0.76 degrees Celsius. Baseline worldwide temperatures were estimated at 14 degrees Celsius.

Even more alarming is the fact that 15 out of 16 of the hottest years in history were recorded in the current century. A combination of the El Nino and the greenhouse gases might have contributed to the extreme conditions, but the effect of the El Nino is expected to die down.

However, the greenhouse effect is expected to have more impact in the world over the long term. There is thus the need for different energy solutions that will be less harmful to the environment.
