The latest Intergovernmental Panel on Climate Change (IPCC) Report,
released on August 9, 2021, reveals that many of the changes observed in
the climate are unprecedented in thousands, if not hundreds of thousands
of years, and some of the changes already set in motionâ??such as
continued sea level riseâ??are irreversible over hundreds to thousands of
The Working Group I report,/Climate Change 2021: the Physical Science
Basis/, is the first installment of the IPCC's Sixth Assessment Report
(AR6), approved by 195 member governments of the IPCC, through a virtual
approval session that was held over two weeks starting on July 26, 2021.
It shows that emissions of greenhouse gases from human activities are
responsible for approximately 1.1Â°C of warming since 1850-1900, and
finds that averaged over the next 20 years, global temperature is
expected to reach or exceed 1.5Â°C of warming.
The report also states that in the coming decades,climate change will
increase in all regions. For 1.5Â°C of global warming, there will be
increasing heat waves, longer warm seasons, and shorter cold seasons. At
2Â°C of global warming, heat extremeswould more often reach critical
tolerance thresholds for agriculture and health, the report shows.
Climate change is not just about temperature, as it will also bring
multiple different changes in different regions, including changes to
wetness and dryness, to winds, snow and ice, coastal areas, and oceans.
Climate change is intensifying the water cycle and affecting rainfall
patterns, while further warming will amplify permafrost thawing. Sea
levels will rise, oceans will warm, and cities will experience more heat
