Winter wave heights and extreme storms on the rise in Western Europe — ScienceDaily

Average winter wave heights along the Atlantic coast of Western Europe have been rising for almost seven decades, according to new research. The coastlines of Scotland and Ireland have seen the largest increases, with the average height of winter waves more than 10mm/year (more than 0.7metres in total) higher than in 1948. That has also led to increased wave heights ...

Technique popularized through social media ranks impact of extinctions — ScienceDaily

A team of researchers is using network analysis techniques — popularized through social media applications — to find patterns in Earth’s natural history, as detailed in a paper published today in the Proceedings of the National Academy of Sciences (PNAS). By using network analysis to search for communities of marine life in the fossil records of the Paleobiology Database, the ...

Carbon capture could be a financial opportunity for US biofuels — ScienceDaily

Although considered critical to avoiding catastrophic global warming, the feasibility of removing carbon dioxide from the atmosphere and storing it underground — known as negative emissions — has been in question. “There’s really no scenario that meets the world’s climate goals without negative emissions,” said Katharine Mach, a senior research scientist at Stanford’s School of Earth, Energy and Environmental Sciences. ...

Hungry birds as climate change drives food ‘mismatch’ — ScienceDaily

Warmer springs create a “mismatch” where hungry chicks hatch too late to feast on abundant caterpillars, new research shows. With continued spring warming expected due to climate change, scientists say hatching of forest birds will be “increasingly mismatched” with peaks in caterpillar numbers. The researchers, from the RSPB and the universities of Exeter and Edinburgh, used data collected across the ...

Grassland plants react unexpectedly to high levels of carbon dioxide — ScienceDaily

Plants are responding in unexpected ways to increased carbon dioxide in the air, according to a twenty-year study conducted by researchers at the University of Minnesota and published in the journal Science. For the first 12 years, researchers found what they expected regarding how different types of grasses reacted to carbon dioxide. However, researchers’ findings took an unanticipated turn during ...

Tiny microenvironments in the ocean hold clues to global nitrogen cycle — ScienceDaily

Nitrogen is essential to marine life and cycles throughout the ocean in a delicately balanced system. Living organisms — especially marine plants called phytoplankton — require nitrogen in processes such as photosynthesis. In turn, phytoplankton growth takes up carbon dioxide from the atmosphere and helps regulate global climate. According to new research by Thomas Weber, an assistant professor of Earth ...

Researchers connect the data to show an accelerating trend for marine heatwaves in our oceans — ScienceDaily

An international study in Nature Communications co-authored by researchers from the ARC Centre of Excellence for Climate Extremes (CLEX) and the Institute of Marine and Antarctic Studies (IMAS) reveals globally marine heatwaves have increased over the past century in number, length and intensity as a direct result of warming oceans. From 1925-2016, the study found the frequency of marine heatwaves ...

Algorithm improves sea level measurements — ScienceDaily

Radar satellites supply the data used to map sea level and ocean currents. However, up until now the radar’s “eyes” have been blind where the oceans are covered by ice. Researchers at the Technical University of Munich (TUM) have now developed a new analysis method to solve this problem. The melting of the polar ice cap would have a drastic ...

Bottlenose dolphins recorded for the first time in Canadian Pacific waters — ScienceDaily

A large group of common bottlenose dolphins (Tursiops truncatus) have been spotted in Canadian Pacific waters — the first confirmed occurrence of the species in this area. The sighting is reported in a study published in the open access journal Marine Biodiversity Records. On 29 July 2017, researchers from Halpin Wildlife Research, in collaboration with the Department of Fisheries and ...
