Global Warming: Earth set to warm 3.2 C by 2100
Earth is set to warm 3.2 C by 2100 and the need to expedite efforts in cutting emissions, globally cannot be emphasized.
The United Nations Environment Programme (UNEP) recently released its annual Emissions Gap Report calling on governments to triple efforts to cut emissions, within the next decade, to limit global warming to 1.5 C or 2 C by 2100.
The report assesses scientific studies on both current greenhouse gas emissions and estimated future emissions, comparing them with possible reduction targets to avoid warming the world more than 1.5 to 2 C.
Some key highlights from the report include:
- Greenhouse gas emissions (GHG) have increased 1.5 per cent annually over the past decade.
- By 2030, annual emissions need to be 15 gigatonnes of CO2 lower to reach the 2 C goal, and 32 gigatonnes lower for 1.5 C.
- GHG emissions have to drop by 2.7 per cent per year from 2020 to 2030 for the 2 C goal, and by 7.6 per cent per year for the 1.5 C target.
- Greenhouse gases accelerated to new peak in 2018
- An ice-free Arctic this century.
Nevertheless, renewables and energy efficiency is one of the key measures to effectively reduce emissions, and the electrification of heat and energy and even transportation could make major headway.
Countries committed to the Paris Agreement and NDCs are set to meet in Madrid on Dec. 2 for the United Nations Climate Change Conference (COP25), and to meet in Glasgow in November 2020 to examine NDC efforts.
