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.
Uncertainties associated with the choice of dry indicators impact future projections of compound hot-dry extremes and are greater than scenario uncertainty in some regions, according to an analysis of different indices from multi-model ensemble simulations.
Defining thresholds for extreme weather events is important for adaptation but often ignores impacts on climate-vulnerable communities. This research finds current practices do not capture experiences of women in informal settlements and self-reported impact data could help to address the issue.
The Maldives are racing to reclaim vast amounts of land to combat rising sea levels. But many are concerned that these efforts risk harming the paradise they aims to protect
The island nation is expanding its territory by dredging up sediment from the ocean floor. But scientists, former government officials and activists say such reclamation can harm marine ecosystems and make the country more vulnerable to rising seas.
Recent policy progress in the United States shows how populism can help advance climate goals, but at a steep cost. Avoiding setbacks will require curbing protectionist reflexes and harnessing opportunities for global cooperation.
The European Court of Human Rights’ judgment in a Swiss case cements the concept that climate inaction violates human rights — responsible nations around the world will take heed.
