The report,prepared by the Intergovernmental Panel on Climate Change (IPCC), is the latest installment that attempts to synthesizs the findings of the previous four reports and present new conclusions that environmental scientists arrived at since the fourth report was released in 2007.
The report concluded that economic and population growth have contributed to greenhouse emissions, which are higher than ever, and caused the earth to warm.
"The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen," the report said, adding that this has caused extreme weather all over the world. "It is very likely that heat waves will occur more often and last longer, and that extreme precipitation events will become more intense and frequent in many regions. The risks that these extreme weather conditions present affect a wide range of people but are most devastating to disadvantaged populations."
"We can't prevent a large scale disaster if we don't heed this kind of hard science," U.S. Secretary of State John Kerry said on Nov. 2 in response to the report. "The longer we are stuck in a debate over ideology and politics, the more the costs of inaction grow and grow."
NBC News wrote that the UN panels report recommends allocating finances to encourage people and governments to come up with new ideas to tackle climate change. IPCC vice chair Jean-Pascal van Ypersele wrote on Twitter that "ordinary people can make choices that reduce climate change, but policymakers have responsibility to facilitate."
