Heavy precipitation speeds carbon exchange in tropics

New research by the University of Montana and its partner institutions gives insight into how forests globally will respond to long-term climate change. Cory Cleveland, a UM professor of terrestrial ecosystem ecology, said that previous research in the wet tropics — where much of global forest productivity occurs — indicates that the increased rainfall that may occur with climate change ...

Marine recovery after mass extinction was likely delayed by further biotic crises

Biotic crises during the Triassic period may have delayed marine recovery after a mass extinction during the late Permian, according to a study published March 15, 2017 in the open-access journal PLOS ONE by William Foster from University of Texas, Austin, USA, and colleagues. The late Permian mass extinction was a catastrophic biotic crisis- an estimated 81 percent of marine ...

China’s severe winter haze tied to effects of global climate change

China’s severe winter air pollution problems may be worsened by changes in atmospheric circulation prompted by Arctic sea ice loss and increased Eurasian snowfall — both caused by global climate change. Modeling and data analysis done by researchers at the Georgia Institute of Technology suggest that sea ice and snowfall changes have shifted China’s winter monsoon, helping create stagnant atmospheric ...

Reconsider the impact of trees on water cycles and climate, scientists say

Forests and trees play a major role on water cycles and cooler temperatures, contributing to food security and climate change adaptation. In recent decades, the climate change discourse has looked at forests and trees mostly as carbon stocks and carbon sinks, but now scientists are calling for more attention on the relation between trees and water in climate change. Scientists ...

Can intergenerational cooperation defeat climate change?

Older adults are powerful allies in addressing climate change, according to “Gray and Green Together: Climate Change in an Aging World,” the latest edition of Public Policy & Aging Report (PP&AR) from The Gerontological Society of America (GSA). Research shows that older adults are at risk for the effects of extreme weather events and climate change; but they are also ...

Assessing the impact of climate risks on the financial system

In the wake of 2015 Climate Paris Agreements to limit global temperature below 2°C above pre-industrial levels, many governmental and private stakeholders have advocated for the introduction of policies to mitigate climate change. This would affect directly only the fossil-fuel and utility sector, but it would also expose indirectly many other economic sectors, in particular the energy-intensive sectors. The financial ...

Models, observations not so far apart on planet’s response to greenhouse gas emissions

How hot our planet will become for a given amount of greenhouse gases is a key number in climate change. As the calculation of how much warming is locked in by a given amount of emissions, it is crucial for global policies to curb global warming. It is also one of the most hotly debated numbers in climate science. Observations ...

Iron dissolved by air pollution may increase ocean potential to trap carbon

Iron particles generated by cities and industry are being dissolved by human-made air pollution and washed into the sea — potentially increasing the amount of greenhouse gases that the world’s oceans can absorb, a new study suggests. Scientists have long believed that acids formed from human-generated pollution and natural emissions dissolve iron in airborne particles — increasing the amount of ...

The new theory of economic ‘agrowth’ contributes to the viability of climate policies

ICTA-Universitat Autonoma de Barcelona (UAB) researcher Jeroen van den Bergh publishes in Nature Climate Change a study in which he proposes a new economic theory compatible with the fight against climate change. The “agrowth” proposal comes up as an alternative to the opposing economic trends of “green growth” and “degrowth” Forty-five years after the first proposal on the limits to ...

No publication bias found in climate change research

Rarely do we encounter a scientific fact that stirs public controversy and distrust in science as much as climate change. However, the theory is built on honest reporting of facts. This emerges from a new study from Lund University in Sweden. The study in question investigates whether there is a so-called publication bias within climate research, i.e. a statistically skewed ...
