Climate change: unchecked gas emissions to make Earth hotter and sooner, UN experts warn

Global temperatures are expected to increase by 1.5 degrees Celsius or more in the next two decades from pre-industrial levels unless “immediate, rapid and large-scale” reductions in greenhouse gases are achieved, climate experts have warned.

Failure to stem the rot could render the goal of limiting global warming to 1.5 degrees by the next decades “beyond reach,” the Intergovernmental Panel on Climate Change (IPCC), a United Nations body, said in a report on Monday. Human activities have raised temperatures by 1.1 degrees since 1850. The Paris climate agreement of 2015 seeks to limit the threshold of 1.5 to 2 degrees by 2100.
