Researchers found recently that glaciers in Himalayan ranges are melting more rapidly than at any point in the last 10,000 years. This means that the water supply in parts of Pakistan, China, India and Nepal will decline soon.
By 2100, the best case scenario is that half of the ice will disappear. Worst-case scenario: two-thirds of it will.

In 2017, 153 billion hours of labor were lost worldwide because of heat, with the largest share in vulnerable rural communities in countries like India. That’s 64 billion more lost labor hours than in 2000.
By mid-century, “Prevalence of heatstroke and extreme weather will have redefined global labor and production beyond recognition,” The Lancet warned in an accompanying editorial. “Multiple cities will be uninhabitable and migration patterns will be far beyond those levels already creating pressure worldwide.”
Though the world still produces more than enough food to feed itself, rising temperatures and extreme weather events are affecting food production. Crop yields are diminishing in 30 countries, reversing a trend of rising agricultural productivity and threatening food security around the world and in the United States.

More than two-thirds of life on Earth died off some 252 million years ago, in the largest mass extinction event in Earth’s history.
Researchers have long suspected that volcanic eruptions triggered “the Great Dying,” as the end of the Permian geologic period is sometimes called, but exactly how so many creatures died has been something of a mystery.
Now scientists at the University of Washington and Stanford believe their models reveal how so many animals were killed, and they see frightening parallels in the path our planet is on today.

A study recently said that agricultural yields could fall to 1980s levels by mid-century in the US due to climate change.
