IPCC: Humans to Blame For Climate Change

Sep 28, 2013 09:09 AM EDT | Matt Mercuro

A report released this week confirmed what many already knew: humans are the "dominate cause" of global warming since 1950.

On Sept. 26 the United Nations' Intergovernmental Panel on Climate Change published its first overview of climate science in six years.

The report, which says scientists are 95 percent certain, details the physical evidence behind climate change.

Despite the news, the report said what has happened the last 15 years is too short to make long-term predictions.

The first part of the IPCC trilogy, which is due sometime over the next year, is a 36-page document considered to be the most "comprehensive statement" on our understanding of a warming planet, according to the BBC News.

The last three decades has been warmer at the Earth's surface, and warmer than any period before 1850. Experts also believe it's probably been warmer than any time during the last 1,400 years.

"Our assessment of the science finds that the atmosphere and ocean have warmed, the amount of snow and ice has diminished, the global mean sea level has risen and that concentrations of greenhouse gases have increased," said Qin Dahe, co-chair of IPCC working group one, who produced the report, according to BBC News.

The report's authors say that humanity is "clearly" responsible for over half of the observed increase in temperatures.

A supposed "pause in the increase" in temperatures the last 15 years makes it hard for experts to make a prediction regarding the future.

"Trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends," the report says.

The report did not support predictions of global warming temperature rises by the end of the century of up to 9 degrees Fahrenheit.

Instead, an increase of 2.7 to 8.1 degrees Fahrenheit is now expected

Sea level rises of 3 to 6 feet are standard, though the panel estimates a more manageable 1.5 feet to 2 feet by the end of the century, according to the report.
