Climate change refers to a statistically defined change in the average and/or variability of the climate system, this includes the atmosphere, the water cycle, the land surface, ice and the living components of Earth. The definition does not usually require the causes of change to be attributed, for example to human activity, but there are exceptions.
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.
Global projections of the economic impacts of climate change have usually focused on rising average temperatures. Now, two studies depict more complex and gloomier scenarios by incorporating variability in temperature and precipitation.
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.
In this Perspective, the authors develop a risk assessment framework for forest microbiomes under climate change that unites microbial and forest ecology. They define processes that amplify or buffer microbial sensitivity and exposure risk and feedbacks that mediate impacts on microbial communities.
Unless the green technological transition underway in Global North countries is globalized, it will fail to reach its developmental potential. To realize the ambitions of green industrial policies in the Global North, technology transfers to the Global South are a necessary supplement to climate finance initiatives.
