The United Nations Intergovernmental Panel on Climate Change (IPCC) has been leading the effort in collecting scientific evidence of climate change and in looking to answer the most important question, is it caused by human activity? Some argue that it is caused mostly by natural variability, and non-human factors. The new IPCC report, released this week, provides more evidence that human activity is a major cause.
The UN is calling for a global response to combat climate change, following new findings by the IPCC stating it is “extremely likely” that humans have been the dominant cause of unprecedented global warming since 1950.
“The heat is on. Now we must act,” Secretary-General Ban Ki-moon said in a video message to the launch of the report of the UN-backed IPCC.
“This new report will be essential for Governments as they work to finalize an ambitious, legal agreement on climate change in 2015,” Mr. Ban said. “The goal is to generate the political commitment to keep global temperature rise below the agreed 2-degree Celsius threshold.”
