Apparently, withdrawing from the Paris climate accord wasn't enough. Now, the Trump administration wants to restrict the world's ability to measure carbon emissions.

Powering the digital world at the expense of the planet — Part 2

How can we build and power our Internet infrastructure to effectively accommodate over 4 billion users while still transitioning to renewable energy in time to avoid dangerous climate change? This is a question that has raised serious discussion.

Powering the digital world at the expense of the planet — Part 1

Since the 1990s, the Internet has become an omnipresent part of everyone's lives, with its user base annually doubling in size and its user-generated content growing uncontrollably. But, facilities that store all that data are now an environmental threat.

Kathmandu - If greenhouse-gas emissions continue to rise, glaciers in the Everest region of the Himalayas could experience dramatic changes in the decades to come.

Global Warming: Arctic permafrost releasing more carbon, methane

A new study shows thawing permafrost in the Arctic, thawing due to global warming, is releasing greenhouse gases in the form of carbon dioxide and methane into the atmosphere. The only good news is that the process is a gradual one.

The loss of tropical rainforests has accelerated by 62 percent

A new study using satellite-based imagery from 1990 to 2010 shows the real extent of tropical rainforest deforestation around the globe. The rate of deforestation was found to have accelerated by 62 percent.

Carbon release contributed to end of last Ice Age

Southampton - Carbon dioxide released from the ocean deeps contributed to ending the last Ice Age, it’s emerged from a new study led by the UK's University of Southampton.

NASA now says vast methane cloud over U.S. southwest is for real

A cloud of methane gas about the size of Delaware was detected over the Four Corners area of the American southwest years ago. The readings were so unusually high that NASA scientists dismissed them. A new study confirms the methane hotspot is real.

New report shows greenhouse gases at unprecedented levels

Surging levels of carbon dioxide around the world have caused greenhouse gases in the atmosphere to reach unprecedented levels. The World Meteorological Organization's annual Greenhouse Gas Bulletin shows GHG concentrations rose 34 percent since 1990.

Op-Ed: Procrastinating 10 years on climate change may be very costly

The Earth's climate is changing, with drought, floods, and falling water levels in our lakes and reservoirs, to raging wildfires and rising sea levels. It's hard not to notice, and the White House is worried about delaying actions on climate change.

Report warns how climate change threatens U.S. economy

Washington - The U.S. economy could face major, systemic disruption due to climate change unless legislators and businesses alike take urgent action to reduce climate risk, says a new report released this week.

Finnish researchers develop new CO2 reduction method

A study from Mikkeli University has discovered a way to use water to remove excess carbon dioxide. This simple method could change how we deal with this highly prevalent greenhouse gas.

CO2 hits 400 parts per million

Geneva - The World Meteorological Association announced Monday that the average monthly concentration of carbon dioxide (CO2) in the northern hemisphere exceeded 400 ppm in April, the highest monthly average on record. Scientists say 'time is running out'

Fracking: Methane levels 1000 higher than EPA stats at some wells

West Lafayette - The furor over fracking took a further twist this week as levels of the greenhouse gas methane were found above drilling wells, in some cases, 1,000 times greater than previous Environmental Protection Agency estimates.

Low-methane kangaroo gas may be key to bovine emissions problem

Kangaroos and cows share a similar diet – mostly grasses and other vegetation. Yet, kangaroos give off a relatively low-methane gas whereas cows and other livestock are a major source of the greenhouse gas.

Atmospheric CO2 levels pass another worrying milestone

San Diego - In May 2013, atmospheric levels of the greenhouse gas, carbon dioxide (CO2) passed a milestone with levels recorded in excess of 400 parts per million (ppm) for the first time ever.

Volcanoes a contributory factor in global warming 'pause'

Livermore - In the climate-change debate, skeptics have made much play of the so-called “pause” in the rise in global surface temperatures over the last 15 years or so.

Op-Ed: What is the so-called 'warm Arctic-cold continent' paradox?

Lately, the media has talked a lot about the "Polar Vortex," and how it has been causing the winter storms and extremely cold weather being experienced in North America. But climate-change skeptics see this as proof the earth is not warming.

Hazards of 6000 gas leaks in aging pipes under Washington D.C.

Washington - Teams of researchers from Boston University and North Carolina’s Duke University have discovered almost 6,000 potentially hazardous gas leaks in aging pipeline infrastructure below the streets of Washington, D.C.

The Amazon’s microbes affect carbon dioxide

The Amazon’s widespread conversion from rainforest to pastureland has significant effects on microorganism communities that may lead to a reduction in the region's role as a reservoir for greenhouse gas.

Meteorite study suggests carbon capture locked up Mars atmosphere

East Kilbride - Examination of a meteorite that’s believed to have fallen to Earth around 3,000 years ago has provided clues as to how Mars lost its atmosphere, previously rich in carbon dioxide (CO2).

Huge population drift augurs as climate change alters ecosystems

Potsdam - Climate change is likely to transform landscapes worldwide, affecting most of Earth’s forests and agriculture — and it isn’t a far future scenario, says a new report. Profound changes in the world’s ecosystems could happen less than 90 years hence

A third of the world's food goes to waste, U.N. says

A U.N. report published on Wednesday says a whole third of the world's food goes to waste, making it the third major source of greenhouse gas emission behind those of U.S. and China.

New records for Arctic ice melt and CO2 emissions during 2012

Boulder - This week, the American Meteorological Society (AMS) published its climatic report card for 2012, “State of the Climate in 2012.” The report makes gloomy reading, highlighting record Arctic ice melt and unprecedented CO2 emissions from fossil fuels.

Australia presses for international ban on geoengineered oceans

Sydney - Australia is pressing for a ban on geoengineering the oceans with iron sulfate, a process which came to prominence last year after an attempt was made to augment salmon stocks off the Canadian Pacific coast by adding chemicals to ocean waters.

Study shows consensus among scientists about climate change

A new study has found that although 33 percent of Americans believe there is "widespread disagreement" among scientists that climate change is happening, there is an overwhelming consensus among environment researchers that it is happening.
