The authors assess the growing field of climate change health impact attribution. They show literature bias towards direct heat effects and extreme weather in high-income countries, highlighting the lack of global representation in current efforts.
The authors use 1,603 estimates of local extinctions from 1980 to 2021 to show that dragonfly species with wing ornamentation have disproportionately gone extinct and lost habitat because of climate change and wildfire. This highlights the important role of mating traits in species survival under change.
The authors evaluate heritable genetic variation in thermal tolerance in a common reef-building coral. They show widespread heritable genetic variation, which is strongly associated with marine heatwave-imposed selective pressure, suggesting adaptation to climate warming.
The gap between adaptation policy planning and actual implementation could delay effective actions. Researchers demonstrate why internal consistency checks should be the starting point to reduce the gap by applying them for city-level adaptation plans across Europe.
The 12 months before July 2024 were more than 1.5 °C warmer than the pre-industrial baseline. Using climate models, the author shows that the first year that exceeds 1.5 °C of warming most probably also occurs within the first 20-year period with an average temperature that exceeds temperature targets.
What a first year with temperature 1.5 °C above the pre-industrial baseline implies for long-term temperature goals is unclear. Here the authors show that such a first year above the baseline is highly likely to occur within the first 20-year period with average warming of 1.5 °C.
