World to breach 1.5°C threshold by 2027-2042

In news

The Intergovernmental Panel on Climate Change had estimated global warming threshold will cross between 2020 and 2052

Highlights
  • The world will heat up more than it can take much earlier than anticipated.
  • The United Nations Intergovernmental Panel on Climate Change (IPCC) had estimated that breach to occur between now and 2052. 
  • The researchers also found that expected warming was a little lower in this period by about 10 to 15 per cent.
  • Global warming projections are unreliable because they depend on faulty supercomputer models.
Mitigation
  • Reducing climate change – involves reducing the flow of heat-trapping greenhouse gases into the atmosphere, either by reducing sources of these gases (for example, the burning of fossil fuels for electricity, heat or transport) or enhancing the “sinks” that accumulate and store these gases (such as the oceans, forests and soil).
  • The goal of mitigation is to avoid significant human interference with the climate system, and “stabilize greenhouse gas levels in a timeframe sufficient to allow ecosystems to adapt naturally to climate change, ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner.
