Ecologists publish research on soil’s potential to increase the Earth’s CO2

MANHATTAN, KANSAS — Soil, an important part of the carbon cycle, might compound the world’s carbon dioxide problem, according to a global study involving Kansas State University researchers and Konza Prairie Biological Station.

The study, “Quantifying global soil carbon losses in response to warming,” recently published in Nature, predicts that soils may release large quantities of carbon dioxide in response to warming, leading to even faster rates of warming globally. The authors, who include Kansas State University’s John Blair, university distinguished ...

Alex Kirby – Arctic Tipping Points Put Earth at Risk

LONDON—If the world fails to slow the pace of climate change very soon by cutting emissions of the greenhouse gases that are heating the planet, Arctic tipping points threaten to overwhelm the region, new research reveals.

Not only that—the authors of the Arctic Resilience Report say the changes that are liable to affect the high northern latitudes could also trigger drastic changes worldwide.

The report, written by an international research team, is a project of the Continue Reading →

Tim Radford – Arctic Ocean could be ice-free before mid-century

LONDON, 5 November, 2016 Two scientists have worked out what it would take to melt all the ice in the Arctic Ocean.

If their sums are right, then by the time human beings have burned enough fossil fuels to add 1,000 billion tons of carbon dioxide to the atmosphere, the Arctic Ocean will be free of ice in September – the annual minimum – and the world’s shipping will have a ...

‘New era of climate change reality’ as emissions hit symbolic threshold

The world is in a new era of “climate change reality”, with carbon dioxide in the atmosphere reaching a symbolic threshold which it will not fall below for many generations, scientists have said.

In 2015, for the first time, carbon dioxide levels in the atmosphere were at 400 parts per million (ppm) on average across the year as a whole, the World Meteorological Organisation’s (WMO) annual greenhouse gas bulletin reveals.

The longest established greenhouse gas monitoring station ...

Kieran Cooke – Tasty insects benefit poor and climate

LONDON, 13 October, 2016 − Eating insects may not be to everyone’s taste, but crickets have for centuries been eaten in many parts of the world − particularly in Asia Pacific region countries, where they are seen as a nutritious snack food, containing far more iron than spinach and other greens.

And now scientists say that eating insects such as crickets can also help lessen the impact of climate change.

Nutritionists point out that crickets have twice the protein level of beef. ...

Andrea Germanos – Methane Emissions From Fossil Fuel Industry May Be 60 Percent Higher Than Estimates: Study

As President Barack Obama heralds the ratification of the Paris climate agreement, a new study shows that methane emissions from the fossil fuel industry are far higher than previously estimated.

According to the research published online Wednesday in the journal Nature, they may be as much as 60 percent greater.

“Our study shows that leaks from oil and gas activities around the world are responsible for a lot more ...

How wetlands and agriculture, not fossil fuels, could be causing a global rise in methane

Research published in the American Geophysical Union’s journal Global Biogeochemical Cycles shows that recent rises in levels of methane in our atmosphere is being driven by biological sources, such as swamp gas, cow burps, or rice fields, rather than fossil fuel emissions.

Atmospheric methane is a major greenhouse gas that traps heat in our atmosphere, contributing to global warming. Its levels have been growing strongly since 2007, and in 2014 the growth rate of methane in the atmosphere was double ...

JEREMY CORBYN – Toward a Green Industrial Revolution

In 2015 the world came together to agree the landmark Paris Climate Agreement aimed at keeping global temperature rises to 1.5 degrees above pre-industrial levels.

And just in time: we are facing a climate crisis. 2016 is set to be the hottest year on record and greenhouse gas emissions globally are still not falling. We are seeing the impacts of climate change much earlier than anyone predicted – around the world and at home.

That’s just one reason why the Labour Party ...

Bruce Melton – We Can Have a Healthy Climate With Zero Warming in Our Lifetimes

We can have a healthy climate — a climate with zero warming — in our lifetimes. The message for the last 20 years has been that we have to reduce emissions drastically to prevent dangerous climate change of more than 2 degrees C (3.6 F). This strategy would have likely worked when it was first suggested, but we have delayed far too long since then. Now, even stringent emissions reductions allow our warming to at least double and likely triple ...

Biofuels increase, rather than decrease, heat-trapping carbon dioxide emissions: study

A new study from University of Michigan researchers challenges the widely held assumption that biofuels such as ethanol and biodiesel are inherently carbon neutral.

Contrary to popular belief, the heat-trapping  gas emitted when biofuels are burned is not fully balanced by the CO2 uptake that occurs as the plants grow, according to a study by research professor John DeCicco and co-authors at the U-M Energy Institute.

The study, based on U.S. Department ...
