To mitigate carbon emissions in the atmosphere, researchers have turned to sinks--reservoirs that accumulate and store carbon such as tropical rainforests, but also including a variety of terrestrial plants as well as oceans. However, another lesser known but very large carbon sink is located along the earth’s soft-sediment shorelines.
All over the world, monitoring stations are registering rising atmospheric levels of the greenhouse gas carbon dioxide. However, in high northern latitudes another trend can also be seen: seasonal variation in carbon dioxide concentration has been increasing since the 1960s. This is mainly due to increasing plant growth in the North, according to a paper published in the latest issue of Science by researchers from the Max Planck Institute of Biogeochemistry in Jena and their colleagues at the Potsdam Institute for Climate Impact Research (PIK) and from the US. Higher temperatures allow more forests to expand, enhancing photosynthesis. In summer, the vegetation absorbs more carbon dioxide.
Current approaches to reconstructing past climate by using tree-ring data need to be improved on so that they can better take uncertainty into account, new University of Otago-led suggests.
Computer simulations help researchers see what works and what doesn't work in the Mediterranean and helps explore future impact of humans
A Yale University study suggests that continent-scale monsoons will adapt to climate change gradually, without suddenly losing their watery oomph.
To date, research on the effects of climate change has underestimated the contribution of seawater expansion to sea level rise due to warming of the oceans.
Carbon capture and storage projects rely on effective monitoring of injected CO2. However, the high number of necessary surveys makes this a costly endeavor. A team of Japanese researchers may have found a means of achieving easier and lower-cost monitoring for leaks of CO2 stored in underground reservoirs. A recently published article from a team led by researchers at Kyushu University's International Institute for Carbon-Neutral Energy Research (I2CNER) shows how underground CO2 storage sites could be continuously monitored for leaks--a breakthrough for monitoring applications.
Scientists from the University of South Florida, along with colleagues in Canada and the Netherlands, have determined that the influx of fresh water from the Greenland ice sheet is "freshening" the North Atlantic Ocean and could disrupt the Atlantic Meridional Overturning Circulation (AMOC), an important component of global ocean circulation that could have a global effect. Researchers say it could impact the future climate in places such as portions of Europe and North America.
The Paris Agreement of the UN climate change conference is deemed a historic step for climate protection, but its success depends on rapid implementations.
Snowshoe hares that camouflage themselves by changing their coats from brown in summer to white in winter face serious threats from climate change, and it’s uncertain whether hare populations will be able to adapt in time, according to a North Carolina State University study.
