First GMO mosquitoes to be released in the Florida Keys

This story was originally published by Undark and is reproduced here as part of the Climate Desk collaboration. This spring, the biotechnology company Oxitec plans to release genetically modified, or GM, mosquitoes in the Florida Keys. Oxitec says its technology will combat dengue fever, a potentially life-threatening disease, and other mosquito-borne viruses — such as Zika — mainly transmitted by the Aedes aegypti mosquito. While […]

Goodbye, old freeways? How subtraction could address climate change

As the coronavirus pandemic ravaged the country last year, then-candidate Joe Biden pushed one message again and again: “Build Back Better.” The phrase now lends its name to the White House’s massive, multi-pronged proposal to help the country recover from the COVID-induced recession, tackle climate change, and bring the country’s railroads, bridges, and water pipes […]

Scientists look for the Holy Grail: The whitest paint ever

White roofs are one of those climate solutions that sound too good to be true. Compared to solar panels and electric cars, painting the roof of a building white is a suspiciously cheap, analog way to usher in a low-carbon future. But it works — white roofs reflect sunlight back into space rather than absorbing […]

Whitest-ever paint could help cool heating Earth, study shows

New paint reflects 98% of sunlight as well as radiating infrared heat into space, reducing need for air conditioning The whitest-ever paint has been produced by academic researchers, with the aim of boosting the cooling of buildings and tackling the climate crisis. The new paint reflects 98% of sunlight as well as radiating infrared heat […]

Did climate change cause societies to collapse? New research upends the old story.

If you’re under the impression that climate change drove ancient civilizations to their demise, you probably haven’t heard the full story.  The ancient Maya, for example, didn’t vanish when their civilization “collapsed” around the 9th century. Though droughts certainly caused hardship, and cities were abandoned, more than 7 million Maya still live throughout Mexico and […]

‘Delay is as dangerous as denial’: scientists urge Australia to reach net zero emissions faster

Heatwaves to double and many properties will be uninsurable if global heating reaches 3C, Australian Academy of Science says Global heating of 3C would more than double the number of annual heatwaves in some parts of Australia, leave properties uninsurable due to flood and fire risk, and make many of the country’s ecosystems “unrecognisable”, according […]

Report: It’s time for the U.S. to research solar geoengineering

To avoid the most disastrous sea-level rise, storms, heat waves, and drought, the best available science says that greenhouse gas emissions must be cut in half in the next decade or so and brought to net-zero by the middle of the century.  But even if global leaders acted to cut emissions at that breakneck pace […]

Climate fight ‘is undermined by social media’s toxic reports’

Scientists warn that Nobel summit and long-term decisions to save the planet are at risk from targeted attacks online Fake news on social media about climate change and biodiversity loss is having a worrying impact in the battle to halt the growing environmental threats to the planet, a group of scientists and analysts have warned. […]

Canadian Conservative party votes not to recognize climate crisis as real

Delegates vote 54%-46% against policy change request Leader O’Toole has sought ambitious climate change agenda Canada’s main opposition Conservative Party members have voted down a proposal to recognize the climate crisis as real, in a blow to their new leader’s efforts to embrace environmentally friendly policies before a likely federal election this year.

Seaweed: A planet-saving, anti-burping drug for cows

How scary are cow burps exactly? Measured by their planet-warming power, methane-filled livestock belches are the equivalent of 850 coal plants burning year-round. But scientists have found that spicing up cattle feed with a little seaweed can dramatically reduce the methane they produce, according to a new study out Tuesday. The promise that feed additives […]
