A NASA study predicts that, if global temperatures keep rising and reach 2
degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels,
people worldwide could face multiple impacts of climate change
simultaneously, with serious consequences.

If global temperatures keep rising and reach 2 degrees Celsius (3.6 degrees
Fahrenheit) above pre-industrial levels, people worldwide could face
multiple impacts of climate change simultaneously. This is according to a
NASA-led study
<https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2022EF003330> that
analyzed the projected impacts of such warming to understand how different
climate effects might combine. A 2-degree rise in global temperatures
is considered
a critical threshold

above
which dangerous and cascading effects of human-generated climate change
will occur.

The researchers found that more than a quarter of the world’s population
could experience an additional month of severe heat stress each year
compared to the middle of the 20th century (1950-1979). High temperatures
and drought could combine dangerously in places like the Amazon, increasing
the risk of wildfire. In the American West, extreme fire weather will
likely be more intense and last longer.
