Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study from the University of Illinois provides answers.
Timber harvested illegally under fraudulent permits is undercutting conservation efforts in the Brazilian Amazon, new research by an international collaboration shows.
Seabirds such as gulls can be key indicators of environmental change as their populations respond to shifts in their ocean habitat over time. A new study from The Auk: Ornithological Advances investigates how several species have responded to changing environmental conditions in the Arctic over the last four decades. The authors find that a warming ocean is directly and indirectly affecting seabird populations in Alaska.
A new study led by the University of Washington uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.
The 1987 Montreal Protocol and the 1997 Kyoto Protocol called for countries around the world to phase out substances that deplete the ozone layer, but many HVAC systems still use synthetic refrigerants that violate those international agreements and inflict environmental damage. Recently, Iranian researchers investigated how natural refrigerants could be used in geothermal heat pumps to reduce energy consumption and operating costs. They report their findings in the Journal of Renewable and Sustainable Energy.
The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. In a new study published today in Nature Communications, an international group of researchers shows that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which a glacier sits in the ocean.
Trees are growing more rapidly due to climate change. This sounds like good news. After all, this means that trees are storing more carbon dioxide from the atmosphere in their wood and hence taking away the key ingredient in global warming. But is it that simple? A team from the Technical University of Munich (TUM) analyzed wood samples from the oldest existing experimental areas spanning a period of 150 years -- and reached a surprising conclusion.
Studies on the contribution of global oceanic warming to winter Eurasian climate change show that there are warmer winters in Europe and the northern part of East Asia.
This summer's worldwide heatwave makes 2018 a particularly hot year. As will be the next few years, according to a study led by Florian Sévellec, researcher at CNRS and at the University of Southampton, and published in the Aug. 14, 2018, edition of Nature Communications. Using a new method, the study shows that at the global level, 2018-2022 may be an even hotter period than expected based on current global warming.
Lack of climate change adaptation among water utilities can put water supplies and the people dependent on them at risk, especially in marginalized communities, a new University of California, Davis, paper suggests.
