A new study finds that by 2150, the seemingly small difference between an increase of 1.5 and 2.0 C would mean the permanent inundation of lands currently home to about 5 million people, including 60,000 who live on small island nations. Even under the best-case climate policy being considered today, many places will still have to deal with rising seas and more frequent coastal floods.

A new landmark study warns that the impact of flooding, droughts and heatwaves by 2050-2100 will exceed previous predictions. The research highlights the substantial challenge European cities face in managing climate risks and underscores the urgent need to design and adapt cities to cope with these future conditions.

The individual commitments made by parties of the United Nations Paris Agreement are not enough to fulfill the overall goal of limiting global temperature rise to less than 2 degrees Celsius above pre-industrial levels. A new study from Stanford University finds that even a 1-degree difference could increase the likelihood of extreme weather.

Researchers found that stabilizing global temperature rise at 1.5 degrees Celsius between now and 2150 would lower the impact of sea-level rise significantly; the global average sea-level in 2150 would be about 7 inches—or 17.7 centimeters—less than under a 2-degree Celsius rise.

New research predicts a significantly drier world if global warming reaches 2ºC. Over a quarter of the world's land could become significantly drier and the change would cause an increased threat of drought and wildfires. Limiting warming to under 1.5ºC would dramatically reduce the fraction of the Earth's surface that undergoes such changes.

A study of the potential temperature-related health impacts of climate change shows that as global temperatures rise, the surge in death rates during heatwaves outweighs any decrease in deaths in cold weather. This will result in many regions facing a sharp net increase in mortality rates.

The consequences of global warming of 1.5°C in Europe will include hotter and more frequent heat waves, and fewer and less intense cold extremes. Extreme rainfall days are expected to become more frequent and intense, and by 2°C warming the impacts worsen. To prevent extreme weather in the future, global warming needs to be limited as much as possible.

A new study has been conducted on how humidity amplifies the impact of heat waves at different global warming levels. It describes where new adaptation efforts might be needed in order to cope with heat stress. Already at 1.5°C and 2°C global warming, regions such as the eastern U.S. and China are projected to experience the most severe heat waves ever recorded.

A new study shows that even a global temperature increase of 1.5°C above pre-industrial levels will be enough for significant changes to the length, intensity, and frequency of heat waves in every part of the world. Almost all regions would experience heatwave events every four years that otherwise would occur only every 30 years.

For the first time, a study has identified a link between climate change and floods in Europe on a continental scale, using a river flow dataset of unparalleled scale and diversity. The changing climate has shifted the timing of floods across Europe during the past 50 years.
