Climate Change Is Real And Accelerated By Human Activity

Scientific evidence for warming of the climate system is unequivocal. – Intergovernmental Panel on Climate Change

Most of the warming occurred in the past 35 years, with 15 of the 16 warmest years on record occurring since 2001.

Two views of Briksdalsbreen (The Briksdal glacier) photographed from nearly the same place. The picture on the left has been taken in the end of July in year 2003 and the another picture on the right has been taken on 4th August 2008. The glacier has decreased while the lake below increased.

The earth is facing some of the most dramatic changes in climate now then it has over the last 650,000. While the earth’s climate has changed through out history with most change occurring due to very small variations in Earth’s orbit that change the amount of solar energy our planet receives, Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities.

According to NASA the current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.

the Intergovernmental Panel on Climate Change in its Fifth Assessment Report a concluded there’s a more than 95 percent probability that human activities over the past 50 years have warmed our planet. The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to 400 parts per million in the last 150 years.

The American Physical Society has said “The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.”

The evidence for rapid climate change is compelling, Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century.

A map of the October 2016 LOTI (land-ocean temperature index) anomaly, showing that the Arctic region was much warmer than average. The United States and North Africa were also relatively warm. The largest area of cooler temperatures stretched across Russia.

Most of the warming occurred in the past 35 years, with 15 of the 16 warmest years on record occurring since 2001. The year 2015 was the first time the global average temperatures were 1 degree Celsius or more above the 1880-1899 average. October 2016 was the second warmest October, for the USA,  in 136 years of modern record-keeping, according to a monthly analysis of global temperatures by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA’s Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005.

Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.
