For a lower climate footprint, vegetarian diet beats local

A new study provides a more comprehensive accounting of the greenhouse gas emissions from EU diets. It shows that meat and dairy products are responsible for the lion's share of greenhouse emissions from the EU diet. »

Rising temperatures and human activity are increasing storm runoff and flash floods

Researchers have demonstrated for the first time that runoff extremes have been dramatically increasing in response to climate and human-induced changes. Their findings show a large increase in both precipitation and runoff extremes driven by both human activity and climate change. »

Availability of nitrogen to plants is declining as climate warms

Researchers have found that global changes, including warming temperatures and increased levels of carbon dioxide in the atmosphere, are causing a decrease in the availability of a key nutrient for terrestrial plants. This could affect the ability of forests to absorb carbon dioxide from the atmosphere and reduce the amount of nutrients available for the creatures that eat them. »

World Heritage Sites threatened by rising sea levels

In the Mediterranean region, there are numerous UNESCO World Heritage Sites in low-lying coastal areas. In the course of the 21st century, these sites will increasingly be at risk by storm surges and increasing coastal erosion due to sea-level rise. »

Can forests save us from climate change?

Additional climate benefits through sustainable forest management will be modest and local rather than global. Even if Europe's forests are managed in such a way that their carbon sequestration is maximized it will not impact the climate significantly. »

Climate models fail to simulate recent air-pressure changes over Greenland

Climatologists may be unable to accurately predict regional climate change over the North Atlantic because computer simulations have failed to include real data from the Greenland region over the last three decades -- and it could lead to regional climate predictions for the UK and parts of Europe being inaccurate. »

New interactive scenario explorer for 1.5 degrees C pathways

IIASA and the Integrated Assessment Modeling Consortium (IAMC) have made the scenarios underlying last week's Intergovernmental Panel on Climate Change (IPCC) 1.5 degrees C Special Report publicly available, in an interactive online resource. »

Does climate vary more from century to century when it is warmer?

Century-scale climate variability was enhanced when the Earth was warmer during the Last Interglacial period (129,000-116,000 years ago) compared to the current interglacial (the last 11,700 years), according to a new study. »

New York City area wetlands may be unwitting generator of greenhouse gasses

A new study suggests that New York City-area wetlands are capable of using CSO inputs in a manner that actually increases greenhouse gas emissions such as carbon dioxide and methane. »

In the absence of bees, flies are responsible for pollination in the Arctic region

Most of the fauna in the Arctic region take part in pollinating, yet during the busiest flowering weeks, there's a shortage of such services. A recent study indicates that the pollination services provided to plants and, thus, the plants' ability to produce seeds are dependent on the timing of the blooming season, and on how many other species are in bloom simultaneously. »

Climate change efforts should focus on ocean-based solutions

The first broad-scale assessment of ocean-based measures to reduce atmospheric carbon dioxide, counteract ocean warming and/or reduce ocean acidification and sea-level rise shows their high potential to mitigate climate change and its impacts. »

More wet and dry weather extremes projected with global warming

Global warming is projected to spawn more extreme wet and dry weather around the world, according to a new study. Those extremes include more frequent dry spells in the northwestern, central and southern United States and in Mexico, and more frequent heavy rainfall events in south Asia, the Indochinese Peninsula and southern China. »

Species-rich forests store twice as much carbon as monocultures

Species-rich subtropical forests can take up on average twice as much carbon as monocultures. An international research team has evaluated data from forests grown specifically for this purpose in China with a total of over 150,000 trees. The results speak in favor of using many different tree species during reforestation. »

Large-scale US wind power would cause warming that would take roughly a century to offset

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. »

A warmer spring leads to less plant growth in summer

Due to climate change, springtime growth begins earlier each year. Up to now, it was thought that this phenomenon was slowing climate change. However, as evaluations of satellite data have now shown, the opposite is the case. »

Global warming increases wildfire potential damages in Mediterranean Europe

Anthropogenic warming will increase the burned areas due fires in Mediterranean Europe, and the increase of the burned area could be reduced by limiting global warming to 1.5ºC. The higher the warming level is, the larger the increase of the burned area is. »

High carbon dioxide levels cause plants to thicken their leaves, could worsen climate change effects

When levels of carbon dioxide in the atmosphere rise, most plants do something unusual: They thicken their leaves. Now scientists have shown that this reaction by plants will actually worsen climate change by making the global 'carbon sink' contributed by plants less productive. »
