Climate science is the study of relatively long-term weather conditions, typically spanning decades to centuries but extending to geological timescales. The discipline is primarily concerned with atmospheric properties – for example temperature and humidity – and patterns of circulation, as well as interactions with the ocean, the biosphere, and, over longer timescales, the geosphere.
A study using multiple satellite observations shows that the land-surface warming due to tropical forest loss is stronger than the cooling due to tropical forest gain. This effect should be included in Earth system models, particularly as tropical afforestation is considered to be a natural climate solution.
Residents of informal settlements suffer from extreme weather due to their precarious living environment. Now, findings show that extreme weather event thresholds do not fully capture the negative impacts experienced by women in Nairobi, Kenya.
Aerosol–cloud interactions are the largest uncertainty in radiative forcing. We combined machine learning and long-term satellite observations to quantify aerosol fingerprints on tropical marine clouds, using degassing volcanic events in Hawaii as natural experiences, and found that cloud cover increased relatively by 50% in humid and stable atmosphere, leading to strong cooling radiative forcing.
The impact of forest loss on land surface temperature in the tropics is five times greater than the response to forest gain, according to satellite observations of temperature and land cover.
Four extreme hydrometeorological events in the Pacific Northwest of North America in 2021, including two cold waves, a heat wave and a major flood, impacted freshwater temperatures by as much as 8 °C in parts of the region, according to an analysis of hourly water temperatures at 554 sites.
Responses of GPT-3.5 and GPT-4 to prompts to list a country’s vulnerability to climate hazards overall agree for floods and cyclones but less for droughts, with fewer errors from GPT-4, indicating a potential to enhance climate literacy, suggests a comparison of responses to hazard risk indices based on data from the IPCC.
Two new gridded, model-ready historical biomass burning emission datasets (BB4CMIPpost and LPJ-LMfirepost) are developed by inverse modeling that leveraged 31 ice core records, existing emissions as a priori, and chemical transport model simulations.
Climate campaigners and politicians rightly concentrate on the benefits of clean energy — but without more support for those who are adversely affected, the backlash will only grow.
