What is the News?<\/b><\/h5>\n
The World Meteorological Organization<\/strong> (WMO) has released its <\/span>Greenhouse Gas Bulletin<\/span> Report ahead of COP26 in <\/span>Glasgow, UK.<\/span><\/p>\n
What are the key findings of the Report?<\/b><\/h5>\nSource: The Hindu<\/figcaption><\/figure>\n
Carbon Dioxide(CO2)<\/b><\/p>\n
Carbon dioxide (CO2) is the most significant greenhouse gas. It has reached 413.2 parts per million in 2020 and is 149% of the pre-industrial level.\u00a0<\/span><\/p>\n
However, the increase in CO2 from 2019 to 2020 was slightly lower than that observed from 2018 to 2019 but higher than the average annual growth rate over the past decade.\u00a0<\/span><\/p>\n
This is despite the approximately 5.6% drop in fossil fuel CO2 emissions in 2020 due to restrictions related to the pandemic.<\/span><\/p>\n
Absorption of CO2<\/b><\/h5>\n
Roughly half of today\u2019s human-emitted CO2 remains in the atmosphere and the other half is absorbed by oceans and land ecosystems, the Bulletin flagged.<\/span><\/p>\n
However, the <\/span>ability of land ecosystems and oceans to act as \u201csinks\u201d may become less effective in future, thus reducing their ability to absorb carbon dioxide and act as a buffer against larger temperature increases.<\/span><\/p>\n
Methane<\/b><\/h5>\n
Methane <\/b>is a powerful greenhouse gas which remains in the atmosphere for about a decade. Methane accounts for about 16% of the warming effect of long-lived greenhouse gases.<\/span><\/p>\n
Approximately 40% of methane is emitted into the atmosphere by natural sources (for example, wetlands and termites), and about 60% comes from anthropogenic sources (for example, ruminants, rice agriculture, fossil fuel exploitation, landfills and biomass burning).<\/span><\/p>\n
Currently,\u00a0 Methane (CH<\/span>4<\/span>) is 262% of the levels in 1750 when human activities started disrupting Earth\u2019s natural equilibrium.\u00a0<\/span><\/p>\n
Nitrous Oxide<\/b><\/h5>\n
Nitrous Oxide<\/b> is both powerful greenhouse gas and an ozone-depleting chemical. It accounts for about 7% of the radiative forcing by long-lived greenhouse gases.<\/span><\/p>\n
N<\/span>2<\/span>O is emitted into the atmosphere from both natural sources (approximately 60%) and anthropogenic sources (approximately 40%), including biomass burning, fertilizer use, and various industrial processes.<\/span><\/p>\n
Currently, nitrous oxide (N<\/span>2<\/span>O)\u00a0 is 123% of the levels in 1750 when human activities started disrupting Earth\u2019s natural equilibrium.\u00a0<\/span><\/p>\n
