SIXTH ASSESSMENT REPORT
Working Group I – The Physical Science Basis
9 August 2021
[Climate Change]
“Recent changes in the climate
are widespread, rapid, and
intensifying, and
unprecedented in thousands
of years.
[Credit:NASA]
“Unless there are immediate,
rapid, and large-scale
reductions in greenhouse gas
emissions, limiting warming to
1.5°C will be beyond reach.
[Credit: Peter John Maridable | Unsplash]
“It is indisputable that human
activities are causing climate
change, making extreme climate
events, including heat waves,
heavy rainfall, and droughts,
more frequent and severe.
[Credit: Yoda Adaman | Unsplash]
“Climate change is already
affecting every region on Earth,
in multiple ways.
The changes we experience will
increase with further warming.
[Credit: Hong Nguyen | Unsplash]
“
There’s no going back from
some changes in the climate
system…
[Credit: Jenn Caselle | UCSB]
“…However, some changes could
be slowed and others could be
stopped by limiting warming.

“There’s no going back from
some changes in the climate
system. However, some
changes could be slowed and
others could be stopped by
limiting warming.
[Credit: Shari Gearheard | NSIDC]
“To limit global warming, strong,
rapid, and sustained reductions in
CO2, methane, and other
greenhouse gases are necessary.
This would not only reduce the
consequences of climate change
but also improve air quality.
