Study Settles Prehistoric Puzzle, Finds Carbon Dioxide Link to Global Warming 22 Million Years Ago
November 14, 2017 12:37 PM - Southern Methodist University

Fossil leaves from Africa have resolved a prehistoric climate puzzle — and also confirm the link between carbon dioxide in the atmosphere and global warming.

Urgent action for planetary health: International Health Lecture
November 14, 2017 10:17 AM - Academy of Medical Sciences (UK)

We need to pay more attention to the health of the planet to save lives, and improve global health, now and in the future, Dr Samuel Myers said at The 2017 Academy of Medical Sciences & The Lancet International Health Lecture

VIMS study identifies tipping point for oyster restoration
November 13, 2017 04:08 PM - Virginia Institute of Marine Science

We’re all familiar with tipping points, when crossing what might seem a minor threshold can lead to drastically different outcomes—the Super Bowl favorite that falls to last place with injury to a single lineman, a tomato seedling that surges skyward the moment it tops the shadowy confines of its clay pot.

Texas' odds of Harvey-scale rainfall to increase by end of century
November 13, 2017 04:02 PM - Massachusetts Institute of Technology (MIT)

As the city of Houston continues to recover and rebuild following the historic flooding unleashed by Hurricane Harvey, the region will also have to prepare for a future in which storms of Harvey’s magnitude are more likely to occur.

Urban Trees are Growing Faster Worldwide
November 13, 2017 11:23 AM - Technical University of Munich (TUM)

Trees in metropolitan areas have been growing faster than trees in rural areas worldwide since the 1960s. This has been confirmed for the first time by a study on the impact of the urban heat island effect on tree growth headed by the Technical University of Munich (TUM). The analysis conducted by the international research team also shows that the growth of urban trees has already been exposed to changing climatic conditions for a long period of time, which is only just beginning to happen for trees in rural areas.

Global carbon dioxide emissions projected to rise after three stable years
November 13, 2017 09:18 AM - Future Earth

By the end of 2017, global emissions of carbon dioxide from fossil fuels and industry are projected to rise by about 2% compared with the preceding year, with an uncertainty range between 0.8% and 3%. The news follows three years of emissions staying relatively flat.

Melting ice sheets will have global impact on ocean tides
November 10, 2017 02:02 PM - Bangor University

Whilst it is widely accepted that sea level is rising because of the melting of the massive sheets covering Greenland and Antarctica, a new paper in the Journal of Geophysical Research: Oceans, by scientists at Bangor University in collaboration with Harvard and Oregon State Universities in the US, and McGill University in Canada, shows that the impact of the melting of these ice sheets will go far beyond just changing water levels. It could have further reaching impacts on global climate.

Research shows ice sheets as large as Greenland's melted fast in a warming climate
November 10, 2017 11:07 AM - Purdue University

New research published in Science shows that climate warming reduced the mass of the Cordilleran Ice Sheet by half in as little as 500 years, indicating the Greenland Ice Sheet could have a similar fate.

Climate change, sparse policies endanger right whale population
November 10, 2017 10:55 AM - Cornell University

North Atlantic right whales – a highly endangered species making modest population gains in the past decade – may be imperiled by warming waters and insufficient international protection, according to a new Cornell analysis published online in Global Change Biology, Oct. 30.

Baltic Clams and Worms Release as Much Greenhouse Gas as 20 000 Dairy Cows
November 10, 2017 09:54 AM - Stockholm University

Worms and clams enhance the release of methane up to eight times more compared to sea bottoms without animals, shows a study by scientists at Stockholm University and Cardiff University.
