Climate change and human survival.

TLDR: The IPCC report shows the need for “radical and transformative change” in the face of climate change.

Abstract: The IPCC report shows the need for “radical and transformative change” Next week the Intergovernmental Panel on Climate Change (IPCC) will publish its report on the impacts of global warming. Building on its recent update of the physical science of global warming,1 the IPCC’s new report should leave the world in no doubt about the scale and immediacy of the threat to human survival, health, and wellbeing. The IPCC has already concluded that it is “virtually certain that human influence has warmed the global climate system” and that it is “extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010” is anthropogenic.1 Its new report outlines the future threats of further global warming: increased scarcity of food and fresh water; extreme weather events; rise in sea level; loss of biodiversity; areas becoming uninhabitable; and mass human migration, conflict and violence. Leaked drafts talk of hundreds of millions displaced in a little over 80 years. This month, the American Association for the Advancement of Science (AAAS) added its voice: “the well being of people of all nations [is] at risk.”2 Such comments reaffirm the conclusions of …

Climate change and human survival

to a temperature rise of at least 2°C—an amount that could be
emitted in less than eight years.” Instead the text should have
read, “The release of just another 275 gigatonnes of carbon
would probably commit us to a temperature rise of at least
2°C—an amount that could be emitted in less than 25 years.”
