As climate changes, boreal forests to shift north and relinquish more carbon than expected

Published by ScienceDaily: Global Warming News on May 05, 2013

New research maps how Earth's myriad climates -- and the ecosystems that depend on them -- could move from one area to another as global temperatures rise. The approach foresees big changes for one of the planet's great carbon sponges. Boreal forests will likely shift north at a steady clip this century.

More hurricanes for Hawaii?

Published by ScienceDaily: Global Warming News on May 05, 2013

Hawaii, fortunately, has been largely free from hurricanes, only two having made landfall in more than 30 years. Now a new study shows that Hawaii could see a two-to-three-fold increase in tropical cyclones by the last quarter of this century.

Brighter clouds, cooler climate? Organic vapors affect clouds, leading to previously unidentified climate cooling

Published by ScienceDaily: Global Warming News on May 05, 2013

Scientists have shown that natural emissions and humanmade pollutants can both have an unexpected cooling effect on Earth's climate by making clouds brighter.

Global highways of invasive marine species calculated

New research has mapped the most detailed forecast to date for importing potentially harmful invasive species with the ballast water of cargo ships.

Boom in jellyfish: Overfishing called into question

Published by ScienceDaily: Global Warming News on May 03, 2013

Will we soon be forced to eat jellyfish? Since the beginning of the 2000s, these gelatinous creatures have invaded many of the world's seas, like the Japan Sea, the Black Sea, the Mediterranean Sea, etc. Is it a cyclic phenomenon, caused by changes in marine currents or even global warming? Until now, the causes remained unknown. A new study exposes overfishing as the main factor.

Lava erupting on sea floor linked to deep-carbon cycle

Published by ScienceDaily: Global Warming News on May 02, 2013

Scientists have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the deep Earth.

Progress in introducing cleaner cook stoves for billions of people worldwide

Published by ScienceDaily: Global Warming News on May 01, 2013

It may be the 21st century, but nearly half the world's population still cooks and heats with open fires or primitive stoves that burn wood, animal dung, charcoal and other polluting solid fuels. A new article describes impressive progress being made to remedy that situation and the obstacles that remain.

Canada's distinctive tuya volcanoes reveal glacial, palaeo-climate secrets

Published by ScienceDaily: Global Warming News on April 30, 2013

Deposits left by the eruption of a subglacial volcano, or tuya, 1.8 million years ago could hold the secret to more accurate palaeo-glacial and climate models, according to new research.

Exploring the saltiness of the ocean to study climate change

Published by ScienceDaily: Global Warming News on April 30, 2013

Details are emerging from a recent research expedition to the Sub-Tropical North Atlantic. The objective of the expedition was to study the salt concentration (salinity) of the upper ocean. Scientists explored the essential role of the ocean in the global water cycle.

The politics of climate change

Published by ScienceDaily: Global Warming News on April 29, 2013

US residents who believe in the scientific consensus on global warming are more likely to support government action to curb emissions, regardless of whether they are Republican or Democrat, according to a new study.
