Role of “natural factors” on recent climate change underestimated, research shows

Pioneering new research has given a new perspective on the crucial role that ‘natural factors’ play in global warming. The study, by Dr Indrani Roy at the University of Exeter, suggests that the natural phenomena such as solar eleven-year cycles and strong volcanic explosions play important roles in recent climate change which has been ‘underestimated’.

Intergovernmental Panel on Climate Change issues warning report

Summary for Policymakers of IPCC Special Report on Global Warming of 1.5ºC approved by governments INCHEON, Republic of Korea, 8 Oct Limiting global warming to 1.5ºC would require rapid, far reaching and unprecedented changes in all aspects of society, the IPCC said in a new assessment. With clear benefits to people and natural ecosystems, limiting

Large-scale shift causing lower-oxygen water to invade Canada’s Gulf of St. Lawrence

The Gulf of St. Lawrence has warmed and lost oxygen faster than almost anywhere else in the global oceans. The broad, biologically rich waterway in Eastern Canada drains North America's Great Lakes and is popular with fishing boats, whales and tourists. A new study led by the University of Washington looks at the causes of

Most land-based ecosystems worldwide risk ‘major transformation’ due to climate change

Without dramatic reductions in greenhouse-gas emissions, most of the planet’s land-based ecosystems—from its forests and grasslands to the deserts and tundra—are at high risk of “major transformation” due to climate change, according to a new study from an international research team. The researchers used fossil records of global vegetation change that occurred during a period

Trapped Hot Water Could Melt All of Arctic’s Ice

Arctic sea ice isn’t just threatened by the melting of ice around its edges, a new study has found: Warmer water that originated hundreds of miles away has penetrated deep into the interior of the Arctic. That “archived” heat, currently trapped below the surface, has the potential to melt the region’s entire sea-ice pack if

Floods in Kerala, India, Show How Unprepared the World Is for Climate Change

The Indian state of Kerala has been devastated by severe floods. More than 350 people have died, while more than a million have been evacuated to over 4,000 relief camps. Tens of thousands remain stranded. The crisis is a timely reminder that climate change is expected to increase the frequency and magnitude of severe flooding across the world. Although no

‘Abrupt thaw’ of permafrost beneath lakes could significantly affect climate change models

Methane released by thawing permafrost from some Arctic lakes could significantly accelerate climate change, according to a new University of Alaska Fairbanks-led study. The study, which was published Aug. 15 in the journal Nature Communications, focuses on the carbon released by thawing permafrost beneath thermokarst lakes. Such lakes develop when warming soil melts ground ice,

Heatwave and climate change having negative impact on our soil say experts

The recent heatwave and drought could be having a deeper, more negative effect on soil than we first realised say scientists. This could have widespread implications for plants and other vegetation which, in turn, may impact on the entire ecosystem. That's because the organisms in soil are highly diverse and responsible not only for producing

Glaciers in East Antarctica also ‘imperiled’ by climate change, UCI researchers find

A team of scientists from the University of California, Irvine has found evidence of significant mass loss in East Antarctica’s Totten and Moscow University glaciers, which, if they fully collapsed, could add 5 meters (16.4 feet) to the global sea level. In a paper published this week in the American Geophysical Union journal Geophysical Research

A Scientist’s Final Paper Looks Toward Earth’s Future Climate

A NASA scientist's final scientific paper, published posthumously this month, reveals new insights into one of the most complex challenges of Earth's climate: understanding and predicting future atmospheric levels of greenhouse gases and the role of the ocean and land in determining those levels. A paper published in the Proceedings of the National Academy of

Climate change increasingly affects small countries

Climate change challenges many countries in the world and is increasingly affecting small countries.  Ministers and other high-level public health officials from the 8 countries that make up the Small Countries Initiative will gather in Reykjavik on 26–27 June to find solutions that can protect their people’s health from this and other threats. Enhanced efforts will

Push to Burn Wood for Fuel Threatens Climate Goals, Scientists Warn

The European Union declared this week that it could make deeper greenhouse gas cuts than it has already pledged under the Paris climate agreement. But its scientific advisors warn that the EU's new renewable energy policy could undermine that goal because it fails to fully account for the climate impacts of burning wood for fuel.

Climate change has fish moving faster than regulations can keep up

The world’s system for allocating fish stocks is being outpaced by the movement of fish species in response to climate change, according to a study undertaken by an international team of marine ecologists, fisheries and social scientists, and lawyers. “Fish fleeing warming waters will cross national boundaries and add new ‘shareholders’ to existing fisheries,” said

Global warming can be limited to 1.5°C by changing how we travel, heat homes, use devices

A new study published in Nature Energy shows that dramatic transformations in the way we move around, heat and cool our homes, and buy and use devices and appliances in our cities can help raise living standards in the global South to meet UN Sustainable Development Goals while also remaining within the 1.5°C target set

Researchers shine a light on more accurate way to estimate climate change

DURHAM, N.H. – It doesn’t matter if it’s a forest, a soybean field, or a prairie, all plants take up carbon dioxide during photosynthesis – the process where they use sunlight to convert water and carbon dioxide into food. During this changeover, the plants emit an energy “glow” that is not visible to the human

Dusty Rainfall Records Reveal New Understanding of Climate

Ancient rainfall records stretching 550,000 years into the past may upend scientists' understanding of what controls the Asian summer monsoon and other aspects of the Earth's long-term climate, reports a University of Arizona-led international team of researchers in the May 25 issue of the journal Science. The standard explanation of the Earth's regular shifts from

Temperature swings to hit poor countries hardest

For every degree of global warming, the study suggests temperature variability will increase by up to 15% in southern Africa and Amazonia, and up to 10% in the Sahel, India and South East Asia. Meanwhile, countries outside the tropics – many of which are richer countries that have contributed most to climate change – should
