Wandering greenhouse gas

On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, it can also become trapped in the sea ice that forms in these coastal waters. »

Half a degree more global warming could flood out 5 million more people

A new study finds that by 2150, the seemingly small difference between a global temperature increase of 1.5 and 2.0 degrees Celsius would mean the permanent inundation of lands currently home to about 5 million people, including 60,000 who live on small island nations. »

Climate change risk for half of plant and animal species in biodiversity hotspots

Up to half of plant and animal species in the world's most naturally rich areas, such as the Amazon and the Galapagos, could face local extinction by the turn of the century due to climate change if carbon emissions continue to rise unchecked. Even if the Paris Climate Agreement 2°C target is met, these places could lose 25 percent of their species. »

Eastern Mediterranean summer will be two months longer by end of 21st century

The eastern Mediterranean is experiencing monumental climate changes poised to significantly affect regional ecosystems and human health. According to a new study, these changes will drastically alter the duration of summer and winter in the region by the end of this century. »

Greenland glaciers' varied vulnerability to melting

Using data from NASA missions observing Earth, researchers have created new maps of the bed topography beneath a score of glaciers in southeast Greenland, thereby gaining a much better understanding of why some are undergoing rapid retreat and others are relatively stable. »

Coral reef experiment shows: Acidification from carbon dioxide slows growth

Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked. The paper represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. »

Global warming increases the risk of avalanches

The impacts of global warming are felt especially in mountainous regions, where the rise in temperatures is above average, affecting both glacierized landscapes and water resources. The repercussions of these changes are manifold and varied, from retreating glaciers to an increase in the frequency and intensity of snow avalanches. »

Exceptionally large amount of winter snow in Northern Hemisphere this year

The new Arctic Now product shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow. This kind of information, which shows the accurate state of the Arctic, becomes increasingly important due to climate change. »

Scientists accurately model the action of aerosols on clouds

Global climate is a tremendously complex phenomenon, and researchers are making painstaking progress, year by year, to try to develop ever more accurate models. Now, an international group using the powerful K computer, have for the first time accurately calculated the effects of aerosols on clouds in a climate model. »

Current deforestation pace will intensify global warming, study alerts

Scientists affirms the prolongation of an annual deforestation of 7,000 square km can nullify the efforts for reducing GHG emissions. The study brings a new assessment on the importance of tropical forests in world climate regulation, and calculates a 0,8 °C rise on Earth's temperature in a scenario in which they are extinct. »

Enhanced weathering of rocks can help to pull CO2 out of the air -- a little

Weathering of huge amounts of tiny rocks could be a means to reduce the greenhouse gases in the atmosphere. While this is normally a slow natural process during which minerals chemically bind CO2, technological upscaling could make this relevant for so-called negative emissions to help limit climate risks. »

Sea level rise urgently requires new forms of decision making

US cities facing sea level rise need to look beyond traditional strategies for managing issues such as critical erosion and coastal squeeze, according to new research. Civil society initiatives must now play a crucial role in adapting society to climate change, the study argues. »

Greenhouse gas emissions of hydropower in the Mekong River Basin can exceed those of fossil fuel energy sources

Hydropower is commonly considered as a clean energy source to fuel Southeast Asian economic growth. A recent study finds that hydropower in the Mekong River Basin, largest river in Southeast Asia, might not always be climate friendly. »

Payments to protect carbon stored in forests must increase to defend against rubber

Efforts to protect tropical forests in Southeast Asia for the carbon they store may fail because protection payments are too low. A new study finds that schemes designed to protect tropical forests from clearance based on the carbon they store do not pay enough to compete financially with potential profits from rubber plantations. »
