Study: How climate change threatens mountaintops (and clean water)

Mountains are far more than rocks. About half of the world’s drinking water filters through their high-elevation forests, plants, and soils, among other natural benefits.

Now, a new first-of-its kind study, in the journal Nature, shows how these mountain ecosystems around the globe may be threatened by climate change.

Rising temperatures over the next decades appear likely to “decouple” key nutrient cycles in mountain soils and plants, an international team of sixteen scientists reports. This is expected to disrupt the function of ...

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 – Vast carbon sink found in Congo basin

A carbon sink as large as 20 years’ worth of US fossil fuel emissions has been identified in peatland in central Africa’s forests.

LONDON, 15 January, 2017 – British scientists have just discovered one of the richest stores of carbon on Earth. They have found 145,000 square kilometres of peatland – an area larger than England – in the forests of the central Congo basin.

The reservoir of compressed plant material holds at least 30 billion metric ...

John Roulac – Spaceship Earth, Your Main Oxygen Systems Are Collapsing

Yes, Houston, we have a problem: Our oceans are dying.

As the brilliant futurist Buckminster Fuller used to point out, our Spaceship Earth is hurtling through space at a great speed.

Imagine if someone told you (a passenger on that ship) that the main oxygen systems were failing because of how food was being grown.

What would you do upon receiving that dire warning? Perhaps work to make a change? Lobby the ship’s captain? Maybe you’d simply deny that there was any such ...

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 ...

Charles Mudede – California Tells Trump It Will Launch Its Own Damn Satellite to Monitor Climate Change

The president of urban America, California Gov. Jerry Brown, gave a speech at the recent American Geophysical Union conference that not only declared war on the backward climate policies of the president of rural America, Donald Trump, but made it very clear that his state has the economic will and power ($2.5 trillion GDP) to pursue its own programs and policies. The things is this: Trump wants to shutdown NASA’s 58-year earth-monitoring project, which includes a set of satellites that ...

UTHealth: Rapid population decline among vertebrates began with industrialization

HOUSTON – (Dec. 15, 2016) – Rapid population decline among vertebrate species began at the end of the 19th century when industrialization was at its peak, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) and the Chinese Academy of Sciences. The research was recently published in Proceedings of the National Academy of Sciences.

“Industrialization is the most natural explanation as to why we have rapid population decline in that period of time. It has to ...

JON AUSTIN – Are we about to be told Chemtrails are REAL? Harvard says emissions could SAVE the Earth

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have identified an aerosol that could be used for “solar geoengineering” to cool the planet, while repairing ozone damage at the same time.

In a new study, published in the Proceedings of the National Academy of Sciences, the scientists said injecting light-reflecting sulphate aerosols into the stratosphere would cool the

planet, but there is a risk of damaging the ozone layer which protects us from harmful UV rays ...
