Carbon concentration

HIGHEST CARBON CONCENTRATION IN ATMOSPHERE IN 3 MILLION YEARS: WMO

What’s in news?

  • Greenhouse gases accelerate to new peak in 2018
  • Greenhouse gases in the atmosphere hit a new record in 2018 says UN, and rising faster than the average rise of the last decade and cementing increasingly damaging weather patterns, the World Meteorological Organization (WMO)
  • The new WMO Greenhouse Gas Bulletin says CO2 concentration in atmosphere has breached all recent records

Key data’s:

  • Rapidly increasing atmospheric levels of CO2 and other greenhouse gases have the potential to initiate unprecedented changes in climate systems, leading to “severe ecological and economic disruptions”.
  • The annual bulletin is based on observations from the WMO Global Atmosphere Watch Programme. These observations help to track the changing levels of greenhouse gases and serve as an early warning system for changes in these key atmospheric drivers of climate change.
  • Population growth, intensified agricultural practices, increases in land use and deforestation, industrialization and associated energy use from fossil fuel sources have all contributed to increases in concentrations of greenhouse gases in the atmosphere since the industrial era, beginning in 1750.
  • The U.N. Environment Programme’s (UNEP) annual “emissions gap” report, assesses whether countries’ emissions reduction policies are enough to meet agreed targets of limiting global warming to 1.5 to 2 degrees Celsius (2.7 to 3.6 Fahrenheit).

History:

  • It is worth recalling that the last time the Earth experienced a comparable concentration of CO2 was 3-5 million years ago.
  • The concentration of carbon dioxide, a product of burning fossil fuels that is the biggest contributor to global warming, surged from 405.5 parts per million in 2017 to 407.8 ppm in 2018, exceeding the average annual increase of 2.06 ppm in 2005-2015.
  • The current level of CO2 concentration in the atmosphere is 147 per cent of pre-industrial levels in 1750. In the period 2017-18, the CO2 level increase was above the average growth rate of the last decade.
  • We need to translate the commitments into action and increase the level of ambition for the sake of the future welfare of the mankind.
