In 1896, Swedish scientist Svante Arrhenius explored whether Earth’s temperatures were influenced by the presence of heat-absorbing gases in the atmosphere. He calculated that if carbon dioxide concentrations doubled, global temperatures would rise by 5°C – even more at the poles.   Just over a century later, the world is on track to fulfilling Arrhenius’

Many people will associate autism with traits including atypical social interactions, repetitive behaviours, and difficulties with speech and communication. But perhaps lesser known is the fact people with autism are more likely to experience gastrointestinal disorders than the general population.   One review found children with autism were four times more likely to report gastrointestinal

The Amazon rainforest is nearing a threshold which, once crossed, would see one of the world’s largest and richest ecosystems morph into arid savannah within half-a-century, scientists said Tuesday.   Another major ecosystem, Caribbean coral reefs, could die off in only 15 years were it to pass its own point-of-no-return, the scientists reported in the

Coronavirus has disrupted everyday life throughout the world through travel bans, flight restrictions and the cancellation of sporting and cultural events. More than 60 million Italians have been banned from travelling, and all public events cancelled. In China, 30 million people are still under lockdown, allowed to leave their homes only every two days.

The world’s tropical forests are rapidly losing their ability to absorb carbon dioxide from greenhouse gas emissions, with the Amazon rainforest at risk of turning from carbon sink to source within 15 years, researchers warned Wednesday.   Tropical forests provide humans with medicine, food, shelter and water and currently account for around half of all

The COVID-19 coronavirus outbreak has caused widespread alarm, travel bans, and the quarantine of multiple cities across the world. But there’s also been an unexpected effect on the environment, in the form of a notable drop in nitrogen dioxide emissions levels across China.   Data collected from the Tropospheric Monitoring Instrument (TROPOMI) on ESA’s Sentinel-5 satellite

The climate crisis poses an escalating threat to scientists everywhere and research of all kinds, scientists in Australia are now warning. The unprecedented wildfires sweeping their nation have been a “brutal wake-up call” to a simple fact: their work is “far from immune” to climate change.   In all its physical and practical glory, science

Australia’s wildfires have destroyed more than a fifth of the country’s forests, making the blazes “globally unprecedented” following a years-long drought linked to climate change, researchers said Monday.   Climate scientists are currently examining data from the disaster, which destroyed swathes of southeastern Australia, to determine to what extent they can be attributed to rising

Antarctica is supposed to be an extremely cold place. The annual mean temperature of the snow-laden continent’s central area is -57 degrees Celsius (−70.6°F); even the coast averages around -10°C (14°F).   But on February 6, the weather station at Esperanza Base on the Antarctic Peninsula – the northernmost tip of the content – logged the hottest temperature

Tiny bubbles of ancient air trapped in ice cores from Greenland suggest we’ve been seriously overestimating the natural cycle of methane, while vastly undervaluing our own terrible impact.   Methane is an ‘invisible climate menace‘ – roughly 30 times more potent as a heat-trapper than carbon dioxide  – and while some of this atmospheric gas

Scientists in Antarctica have recorded a new record temperature of 20.75 degrees Celsius (69.35 Fahrenheit), breaking the barrier of 20 degrees for the first time on the continent, a researcher said Thursday.   “We’d never seen a temperature this high in Antarctica,” Brazilian scientist Carlos Schaefer told AFP. He cautioned that the reading, taken at

Overlapping environmental crises could tip the planet into “global systemic collapse,” more than 200 top scientists warned Wednesday. Climate change, extreme weather events from hurricanes to heatwaves, the decline of life-sustaining ecosystems, food security and dwindling stores of fresh water – each poses a monumental challenge to humanity in the 21st century.   Out of 30

Permafrost in Canada, Alaska and Siberia is abruptly crumbling in ways that could release large stores of greenhouse gases more quickly than anticipated, researchers have warned.   Scientists have long fretted that climate change – which has heated Arctic and subarctic regions at double the global rate – will release planet-warming CO2 and methane that

Antarctica’s Thwaites Glacier hasn’t been doing so well. It’s close to irreversibly melting, it has a huge cavity growing underneath it, and it’s the poster child for everything wrong with our reliance on fossil fuels.   But a robotic underwater vehicle called Icefin just snapped the first pictures of Thwaites’ foundations of the ocean floor,
