The seasonal greening of Northern Hemisphere (NH) ecosystems, due to extended growing periods and enhanced photosynthetic activity, could modify near-surface warming by perturbing land-atmosphere energy exchanges, yet this biophysical control on warming seasonality is underexplored. By performing experiments with a coupled land-atmosphere model, here we show that summer greening effectively dampens NH warming by -0.15 ± 0.

- Solar geoengineering (SG) and cutting down CO emissions can both help with climate change, but how they affect food production is still not totally clear.
- Researchers used a special crop model to see how six major crops would respond to different SG techniques and emissions cuts, finding that while all methods can cool down the planet enough to help crops, they have different effects on the crop yields.
- Overall, they learned that SG techniques could increase global crop yields by about 10%, while reducing emissions could lower yields by 5%, especially because less CO means less plant growth benefit.
Understanding the variations in spring vegetation phenology associated with preseason climate conditions can significantly improve our knowledge on ecosystem dynamics and biosphere-atmosphere interactions. Recent studies have shown that wet winters can delay the start date of the vegetation growing season (SOS) in the high latitudes. However, associated underlying mechanisms remain unclear due to the lack of observation sites as well as complex interactions between various climate and ecosystem variables.
