Evaluation of climate adaptation policies typically compares differences between scenarios with different levels of, or without, climate change. Many policies, however, address development simultaneously, and focusing only on climate change impacts may not identify the best outcome.Nature Climate Change, Published online: 2021-04-15; doi:10.1038/s41558-021-01030-92021-04-15 DOI: 10.1038/s41558-021-01030-9

Mountain snowpack in western North America is decreasing, and these trends are often reported using amount of maximum annual snowpack. An alternative metric — integrated snowmelt during the accumulation season — finds snowmelt decreases are three times more widespread, suggesting even stronger snow decline.Nature Climate Change, Published online: 2021-04-05; doi:10.1038/s41558-021-01024-72021-04-05 DOI: 10.1038/s41558-021-01024-7
Thawing Arctic permafrost, and release of its stored carbon, is a known amplifier of global warming. Now research suggests an increase in Arctic lightning could speed up the permafrost’s demise.Nature Climate Change, Published online: 2021-04-05; doi:10.1038/s41558-021-01016-72021-04-05 DOI: 10.1038/s41558-021-01016-7
Mountain snowpack declines are often tracked using snow water equivalent trends sensitive to highly variable precipitation. Observational work proposes temperature-driven daily snowmelt during the accumulation season as an alternative metric, with increases that are three times more widespread.Nature Climate Change, Published online: 2021-04-05; doi:10.1038/s41558-021-01014-92021-04-05 DOI: 10.1038/s41558-021-01014-9
Changes in lightning activity are uncertain under climate change. The authors project that summer lightning in the Arctic is likely to more than double by the end of the century, with implications for lightning-strike tundra wildfires and associated carbon release from permafrost.Nature Climate Change, Published online: 2021-04-05; doi:10.1038/s41558-021-01011-y2021-04-05 DOI: 10.1038/s41558-021-01011-y
This month marks 10 years since the first issue of Nature Climate Change. In this issue, we reflect on developments in research areas over those years and celebrate some memorable papers published in our pages.Nature Climate Change, Published online: 2021-04-01; doi:10.1038/s41558-021-01029-22021-04-01 DOI: 10.1038/s41558-021-01029-2
Raising agricultural productivity has been essential for global food security and conserving land. Now, research quantifies how climate change has slowed agricultural productivity growth around the world.Nature Climate Change, Published online: 2021-04-01; doi:10.1038/s41558-021-01017-62021-04-01 DOI: 10.1038/s41558-021-01017-6
