Researchers set out to learn how extreme winter cold and heat affected 41 common bird species in eastern North America. They found that individual bird species respond differently to these weather events, and extreme winter heat may lead to longer-term changes in bird populations.
Many countries promote the expansion of wind farms. However, if these offshore wind farms are set up close to each other, wind energy and hence electricity yield is reduced. A study by the Helmholtz Zentrum Hereon, which has now been published in the journal Nature Scientific Reports, shows that the losses with increasing offshore wind energy production will be considerable and detectable as large scale pattern of reduced wind speed around wind farms.
Under global warming, tipping elements in the Earth system can destabilize each other and eventually lead to climate domino effects. The ice sheets on Greenland and West Antarctica are potential starting points for tipping cascades, a novel network analysis reveals. The Atlantic overturning circulation would then act as a transmitter, and eventually elements like the Amazon rainforest would be impacted. The consequences for people would reach from sea-level rise to biosphere degradation.
High resolution climate models can improve predictions of extreme rainfall events. An international study involving CMCC scientists presents the first multi-model ensemble of high-resolution regional climate models and offers a promising prospect for studies on climate and climate change at local and regional scales.
An international team of researchers, led by the Max Planck Institute for Chemistry in Mainz, Germany, has now succeeded in reconstructing changes in rainfall in Central Asia over the past five million years. The information preserved within the sedimentary succession provides the missing link for understanding land-water feedbacks for global climate.
A study of two methods for reconstructing ancient temperatures has given climate researchers a better understanding of just how cold it was in Antarctica during the last ice age around 20,000 years ago.
Sea ice thickness is inferred by measuring the height of the ice above the water, and this measurement is distorted by snow weighing the ice floe down. Scientists adjust for this using a map of snow depth in the Arctic that is decades out of date. In the new study, researchers swapped this map for the results of a new computer model designed to estimate snow depth as it varies year to year.
Researchers from University of Toronto Engineering have developed an improved electrochemical system that raises the value of captured CO2 by converting more of it into valuable products than ever before.
Launching the UN Decade on Ecosystem Restoration, a new UN report says that to address climate change, loss of nature and pollution, the world must deliver on existing commitments to restore at least 1 billion degraded hectares of land -- an area comparable to China - in the next decade and add similar commitments for oceans. The report documents the urgent need for restoration, the financial investment required, and the potential returns for people and nature.
Amid the steady growth of solar energy production in the United States, pollinator conservation at solar installations has become an appealing secondary pursuit, but the long-term success of such efforts remains to be seen. In a new article published today in the journal Environmental Entomology, a group of entomologists say pairing solar energy with pollinator habitat offers great promise, but scientific evaluation and meaningful standards will be key to making it a true win-win combination.
