Researchers have found new evidence that global warming is affecting the size of commercial fish species, documenting for the first time that juvenile fish are getting bigger, as well as confirming that adult fish are getting smaller as sea temperatures rise.
A research team from the Niels Bohr Institute has found that missing data in a recent IPCC report could have underestimated the rate of sea-level rise.
A new study by the National Center for Atmospheric Research (NCAR) reports that the lockdowns and decrease in societal activity associated with the COVID-19 pandemic influenced emissions of pollutants such that the planet was slightly warmed for several months last year.
When assessing the rise in sea levels, two major elements should be observed. One element is the loss of ice on land, for example, inland ice sheets and melting mountain glaciers on Antarctica and Greenland, while the other is that the sea will increase in size as it becomes warmer.
Soil temperature has a significant impact on land-atmosphere interaction within the Earth system, affecting surrounding ecology, agriculture, and much more. This influence is a primary component of what is called a "thermal regime" of land, or a regular pattern of temperature change within the soil. Climatologists are intrigued by fluctuating soil temperatures, especially during the first decade of the 21st century where global surface warming has slowed down.
Antarctic ice is melting, contributing massive amounts of water to the world's seas and causing them to rise - but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years' worth of satellite data indicates.
The most significant greenhouse gas, next only to carbon dioxide (CO2), is methane (CH4). The concentration of CH4 in the atmosphere has increased over two times since the preindustrial age because of the increased emissions due to human activities.
For the first-ever time, scientists from the University of Helsinki have shown how the surrounding impacts the formation of nanoparticles in the Arctic. The findings provide a better understanding of the future of melting sea ice and the Arctic atmosphere.
When thick, the surface layer of the ocean acts as a buffer to extreme marine heating--but a new study from the University of Colorado Boulder shows this "mixed layer" is becoming shallower each year. The thinner it becomes, the easier it is to warm. The new work could explain recent extreme marine heatwaves, and point at a future of more frequent and destructive ocean warming events as global temperatures continue to climb.
Earth is warming rapidly, but there is too little observational data in some regions such as the Arctic or high-altitude areas like the Qinghai-Tibetan plateau to adequately and consistently assess temperature variations across the globe.
