Role of terrestrial biosphere in counteracting climate change may have been underestimated

It is widely known that the terrestrial biosphere (the collective term for all the world’s land vegetation, soil, etc.) is an important factor in mitigating climate change, as it absorbs around 20% of all fossil fuel CO2 emissions. However, its role as a net carbon sink is affected by land-use changes such as deforestation and expanded agricultural practice.

A new study, conducted by an international collaboration of scientists and published in the journal Nature Geoscience, has analysed the extent to which ...

Climate models may underestimate future warming on tropical mountains

PROVIDENCE, R.I. [Brown University] — In few places are the effects of climate change more pronounced than on tropical peaks like Mount Kilimanjaro and Mount Kenya, where centuries-old glaciers have all but melted completely away. Now, new research suggests that future warming on these peaks could be even greater than climate models currently predict.

Researchers led by a Brown University geologist reconstructed temperatures over the past 25,000 years on Mount Kenya, Africa’s second-highest peak after Kilimanjaro. The work shows that as ...

Jeannie Kever – Researchers Report New Understanding of Global Warming

Researchers know that more, and more dangerous, storms have begun to occur as the climate warms. A team of scientists has reported an underlying explanation, using meteorological satellite data gathered over a 35-year period.

The examination of the movement and interaction of mechanical energies across the atmosphere, published Jan. 24 in the journal Nature Communications, is the first to explore long-term variations of the Lorenz energy cycle – a complex formula used to describe the interaction between potential and kinetic energy ...

Tim Radford – Global warming will hit US northeast hard

US scientists provide new reality check for Donald Trump on the combined stresses of global warming and the rising costs of water.

LONDON, 18 January, 2017 – America’s north-eastern states are set to become hotter on average than the rest of the world as a result of global warming.

New research by scientists in the US predicts that even if the nations of the planet do succeed in containing global warming to an average of 2°C above pre-industrial levels by ...

Nadia Prupis – Global Sea Ice Hits Lowest Levels ‘Probably in Millenia’

Global sea ice levels are at their lowest in recorded history, according to new statistics from the U.S. National Snow & Ice Data Center.

In the Arctic, the loss is due to climate change and extreme weather events that are likely influenced by global warming, while the changes in the Antarctic may be attributed to natural variability, the center said.

But as a result of the declines in both regions, the total loss of ice is likely at the lowest it’s ...

Graham Readfearn – How Donald Trump Kingmaker-Billionaires Robert and Rebekah Mercer Have Poured Millions Into Climate Science Denial

When it comes to climate science denial, some names come easily and deservingly to mind.

There’s oil giant ExxonMobil — a company that contributed millions of dollars to organizations that told the public there was no risk from burning fossil fuels.

There are the oil billionaire Koch brothers — Charles and David — and their ideological zeal against government regulations that drove them to pour vast amounts into groups spreading doubt on the realities of human-caused global warming.

But a name that has ...

Alexandra Jacobo – New study confirms findings of faster global warming, despite what the GOP claims

A new study has confirmed what the National Oceanic and Atmospheric Administration originally found in 2015 – the oceans are warming at nearly twice the rate we originally thought.

After publishing their findings in 2015, the NOAA was immediately attacked by members of the GOP. GOP members of the House Science, Space, and Technology Committee, headed by Rep. Lamar Smith, opened an investigation into the conclusions. According to Smith, “NOAA has failed to fully explain the ...

Andrea Germanos – New Study ‘Sounds Alarm’ on Another Climate Feedback Loop

The loss of Arctic sea ice has already been shown to be part of a positive feedback loop driving climate change, and a recent study published in the journal Nature puts the spotlight on what appears to be another of these feedback loops.

It has to do with soil, currently one of Earth’s carbon sinks. But warming may lead to soils releasing, rather than sequestering, carbon.

As study co-author John Blair, university distinguished professor of biology at Kansas State ...

Arctic ice melt ‘already affecting weather patterns where you live right now’

The dramatic melting of Arctic ice is already driving extreme weather that affects hundreds of millions of people across North America, Europe and Asia, leading climate scientists have told the Guardian.

Severe “snowmageddon” winters are now strongly linked to soaring polar temperatures, say researchers, with deadly summer heatwaves and torrential floods also probably linked. The scientists now fear the Arctic meltdown has kickstarted abrupt changes in the planet’s swirling atmosphere, bringing extreme ...

Nika Knight – Methane Emissions Are Soaring, Report Finds, and Agriculture Is to Blame

Mere months after atmospheric carbon dioxide permanently surpassed a symbolic threshold of 400 parts per million, scientists have more bad news: emissions of methane, a more potent greenhouse gas, have skyrocketed in the past 20 years—and show no sign of slowing.

That’s according to a new analysis published Monday in the journal Environmental Research Letters.

The report, The Growing Role of Methane in Anthropogenic Climate Change, finds that “methane concentrations in the air began to surge around 2007 and grew precipitously ...
