The short version

A recent UN study puts the best-case warming scenario at 1.7 to 1.8C, above the 1.5C limit agreed a decade ago.[NPR]
Researchers found each tenth of a degree of warming exposes about 140 million more people to dangerous heat.[NPR]
The IPCC found that beyond 2C of warming, 99% of corals would be lost, and researchers found 44% of coral species were already at risk of extinction.[NPR]

A decade ago, countries agreed to limit climate warming to 1.5 degrees Celsius.[NPR]
A recent United Nations study says the best-case warming scenario is now 1.7 or 1.8 degrees Celsius.[NPR]
Researchers found that each tenth of a degree of warming exposes an additional 140 million people to dangerous heat.[NPR]
The Intergovernmental Panel on Climate Change found that beyond 2 degrees Celsius of warming, 99% of corals would be lost.[NPR]
Researchers found that 44% of coral species globally were at risk of extinction even before the 2023 to 2025 bleaching event.[NPR]
Warmer air holds about 7% more water vapor for every degree, which can produce heavier downpours.[NPR]

Only NPR is reporting this event in the provided set, so the figures have not been independently corroborated by other outlets.[NPR]
The estimated 50,000 heat-related deaths in Europe last summer are an estimate, not a confirmed count.[NPR]

Outlet counts describe coverage, not independent confirmation. Reports may share a wire service or original source.
