Temperatures to rise 1.5 degrees Celsius by 2030-2052 without rapid steps – U.N. report

INCHEON, SOUTH KOREA (OCTOBER 8, 2018) (INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE) – Temperatures are likely to rise by 1.5 degrees Celsius between 2030 and 2052 if global warming continues at its current pace and if the world fails to take rapid and unprecedented measures to stem the increase, a U.N. report said on Monday (October 8).

The U.N. Intergovernmental Panel on Climate Change (IPCC) met last week in Incheon, South Korea to finalize the report, prepared at the request of governments in 2015 when a global pact to tackle climate change was agreed.

The report is seen as the main scientific guide for government policymakers on how to implement the 2015 Paris Agreement. The Paris pact aims to limit global average temperature rise to “well below” 2C above pre-industrial levels, while seeking to tighten the goal to 1.5C.

The targets agreed in Paris on cutting emissions would not be enough even if there were larger and more ambitious cuts after 2030, it said.

To contain warming at 1.5C, manmade global net carbon dioxide emissions would need to fall by about 45 percent by 2030 from 2010 levels and reach “net zero” by mid-century. Any additional emissions would require removing CO2 from the air.
