Propping up glaciers to avoid cataclysmic sea level rise

by Marlowe HOOD Agence France Presse PARIS, France (AFP) — As global warming outpaces efforts to tame it, scientists have proposed building massive underwater structures to prevent an Antarctic glacier the size of Britain from sliding into the sea and lifting the world’s oceans by several meters. The more modest of two engineering schemes — which is still on the scale of a Panama or Suez Canal — to shore up Thwaites Glacier would require […]

Global warming will make insects hungrier, eating up key crops: study

by Kerry SHERIDAN Agence France Presse TAMPA, United States (AFP) — Researchers have found a new way that global warming is bad for the planet: more hungry bugs. Rising temperatures will stimulate insects’ appetites — and make some prone to reproducing more quickly — spelling danger for key staples like wheat, corn and rice which feed billions of people, researchers said Thursday. And since these three crops account for 42 percent of the calories people […]

Ten ways the planet could tip into ‘Hothouse Earth’

  by Marlowe Hood Agence France Presse PARIS, France (AFP) — Even if humanity slashes greenhouse gas emissions in line with Paris climate treaty goals, the planet could overwhelm such efforts and irretrievably tip into a hellish ‘hothouse’ state, top scientists warned Monday. Under such a scenario, Earth’s average temperature would stabilize 4 or 5 degrees Celsius above pre-industrial levels, rather than the 1.5 C to 2 C (2.7 or 3.6 Fahrenheit) cap called for […]

Global warming will make veggies harder to find: study

TAMPA, United States (AFP)—Global warming is expected to make vegetables significantly scarcer around the world, unless new growing practices and resilient crop varieties are adopted, researchers warned on Monday. By the end of this century, less water and hotter air will combine to cut average yields of vegetables — which are crucial to a healthy diet — by nearly one-third, said the report in the Proceedings of the National Academy of Sciences. A 7.2 Fahrenheit […]

Global warming may have ‘devastating’ effects on rice: study

by Kerry Sheridan Agence France Presse TAMPA, United States (AFP) — As carbon dioxide rises due to the burning of fossil fuels, rice will lose some of its protein and vitamin content, putting millions of people at risk of malnutrition, scientists warned on Wednesday. The change could be particularly dire in southeast Asia where rice is a major part of the daily diet, said the report in the journal Science Advances. “We are showing that […]

Microplastics in Arctic sea ice – ‘nowhere is immune’

by Mariëtte Le Roux Agence France-Presse PARIS, France (AFP) — Researchers warned Tuesday of a “troubling” accumulation of microplastics in sea ice floating in the Arctic ocean, a major potential source of water pollution as global warming melts the sheets of frozen water. A team from the Alfred Wegener Institute for Polar and Marine Research (AWI) found 17 different plastic types in ice samples gathered during three Arctic expeditions on board the research icebreaker Polarstern […]

Videographics: Polar ice caps melting as Arctic heats up

The world’s polar ice caps are shrinking little by little. The Arctic is heating up twice as fast as the rest of the planet…with Greenland’s glaciers receding particularly quickly. This process is speeding up all by itself. Melting snow exposes ice underneath, which then absorbs the sun’s rays and increases thawing. At the opposite end of the earth, 90% of the ice shelves on the Antarctic Peninsula are starting to disintegrate. Ice melt is also […]

Global warming will expose millions more to floods

MIAMI, United States (AFP) — Global warming is expected to unleash more rain, exposing millions more people to river flooding particularly in the United States and parts of Asia, Africa and central Europe, researchers said Wednesday. The study in the journal Science Advances calculates how much more flood protection will be needed to keep the risks of high-end floods constant in the next 25 years. Unless actions are taken — such as enhancing dikes, boosting […]

Trump says US could ‘conceivably’ return to Paris climate deal

WASHINGTON, United States (AFP) — President Donald Trump said on Wednesday that the United States could “conceivably” return to the Paris climate accord, although he stopped short of signalling any move in that direction. “Frankly, it’s an agreement that I have no problem with, but I had a problem with the agreement that they signed, because, as usual, they made a bad deal,” Trump told a news conference. “So we can conceivably go back in,” […]

Arnold Schwarzenegger says “act now” on climate change

BONN, Germany (Reuters) — Former California governor-turned-green activist, Arnold Schwarzenegger, said on Sunday (November 12) he would do everything in his power to make sure the Paris climate agreement is implemented. Speaking at an event event organized by local and regional governments on the sidelines of the Bonn talks on global warming, the former Hollywood star also said it was everyone’s responsibility to act. The Austrian-born actor, who served two terms as California governor, also […]
