Elemental haiku. The ozone hole over the South Pole is now bigger than Antarctica. The ozone depletes and forms a hole over the Antarctic in the Southern Hemisphere's spring, which is from August to October.
It typically reaches its largest size between mid-September and mid-October, according to Copernicus. What We Know About Climate Change and Hurricanes. Earth Temperature Timeline. A NASA scientist explains why the weather is becoming more extreme. AcrossAcross China and Western Europe in July, the amount of rain that might typically fall over several months to a year came down within a matter of days, triggering floods that swept entire homes off their foundations.
In June, the usually mild regions of Southwest Canada and the US’s Pacific Northwest saw temperatures that rivaled highs in California’s Death Valley desert. The severe heat was enough to buckle roads and melt power cables. Yesterday, a landmark United Nations report helped put those kinds of extreme events into context. By burning fossil fuels and releasing planet-heating greenhouse gases into the atmosphere, humans are fueling more dangerous weather. Researchers have been able to connect the dots between greenhouse gas emissions and climate change for decades. Space and NASA.
Science explains world. The Colorado River Drought Is A Crisis For The West. Caitlin Ochs for BuzzFeed News A woman sunbathes next to a swimming pool overlooking a golf course and Lake Powell in Arizona.
Bob Martin’s floor-to-ceiling office windows overlooking Lake Powell have become a constant source of stress. IPCC report shows ‘possible loss of entire countries within the century’ Global heating above 1.5C will be “catastrophic” for Pacific island nations and could lead to the loss of entire countries due to sea level rise within the century, experts have warned.
The Pacific has long been seen as the “canary in the coalmine” for the climate crisis, as the region has suffered from king tides, catastrophic cyclones, increasing salinity in water tables making growing crops impossible, sustained droughts, and the loss of low-lying islands to sea level rise. A world of hurt: 2021 climate disasters raise alarm over food security. Human-driven climate change is fueling weather extremes — from record drought to massive floods — that are hammering key agricultural regions around the world.From the grain heartland of Argentina to the tomato belt of California to the pork hub of China, extreme weather events have driven down output and driven up global commodity prices.Shortages of water and food have, in turn, prompted political and social strife in 2021, including food protests in Iran and hunger in Madagascar, and threaten to bring escalating misery, civil unrest and war in coming years.Experts warn the problem will only intensify, even in regions currently unaffected by, or thriving from the high prices caused by scarcity.
Global transformational change is urgently needed in agricultural production and consumption patterns, say experts.
Why Extreme Heat Is So Deadly. In June a massive “heat dome” smothered the famously temperate Pacific Northwest, subjecting parts of Washington State, Oregon and western Canada to blistering and unprecedented temperatures.
Lytton, British Columbia, set an all-time Canadian record with a searing 121.3 degrees Fahrenheit (49.6 degrees Celsius). A day later most of that village was destroyed by a huge wildfire. During another western heat wave in early July, California’s Death Valley reached a scorching 130 degrees F (54 degrees C)—just shy of its record of 134 degrees F (57 degrees C), which was reported in 1913 (and is somewhat disputed now). A third heat wave blanketed the U.S. and Canadian West in recent days. (1) Huge “dead zone” forming off the coast of Oregon, Washington.
New clues to why there's so little antimatter in the universe. Imagine a dust particle in a storm cloud, and you can get an idea of a neutron's insignificance compared to the magnitude of the molecule it inhabits.
But just as a dust mote might affect a cloud's track, a neutron can influence the energy of its molecule despite being less than one-millionth its size. And now physicists at MIT and elsewhere have successfully measured a neutron's tiny effect in a radioactive molecule. The team has developed a new technique to produce and study short-lived radioactive molecules with neutron numbers they can precisely control. Refusing to act on climate change will cost future generations $530 trillion (at least) - Techly. By continuing to delay significant reductions in greenhouse gas emissions, we risk handing young people alive today a bill of up to US$535 trillion.
This would be the cost of the “negative emissions” technologies required to remove CO₂ from the air in order to avoid dangerous climate change. These are the main findings of new research published in Earth System Dynamics, conducted by an international team led by US climate scientist James Hansen, previously the director of NASA’s Goddard Institute for Space Studies.
The Paris Agreement in 2015 saw the international community agree to limit warming to within 2°C. The Hansen team argue that the much safer approach is to reduce atmospheric concentrations of CO₂ from the current annual average of more than 400ppm (parts per million) back to 1980s levels of 350ppm. This is a moderately more ambitious goal than the aspiration announced in Paris to further attempt to limit warming to no more than 1.5°C. Climate change: Europe's melting glaciers. Bug Die Off: Collapse of insect populations is bad news for humans. David Attenborough Netflix documentary: Australian scientists break down in tears over climate crisis. One of Australia’s leading coral reef scientists is seen breaking down in tears at the decline of the Great Barrier Reef during a new Sir David Attenborough documentary to be released globally on Friday evening.
Prof Terry Hughes is recounting three coral bleaching monitoring missions in 2016, 2017 and 2020 when he says: “It’s a job I hoped I would never have to do because it’s actually very confronting …” before tears cut him short. The emotional scene comes during the new Netflix documentary, Breaking Boundaries: The Science of Our Planet, and shows the toll the demise of the planet’s natural places is having on some of the people who study them.
The film visits scientists working on melting ice, the degradation of the Amazon, and the loss of biodiversity, and looks at a 2019/2020 “summer from hell” for Australia that featured unprecedented bushfires and the most widespread bleaching of corals ever recorded on the Great Barrier reef. Fleeing climate change — the real environmental disaster. Universe & Multiverse. Quantum Playground. A quantum experiment suggests there’s no such thing as objective reality. Back in 1961, the Nobel Prize–winning physicist Eugene Wigner outlined a thought experiment that demonstrated one of the lesser-known paradoxes of quantum mechanics.
The experiment shows how the strange nature of the universe allows two observers—say, Wigner and Wigner’s friend—to experience different realities. Since then, physicists have used the “Wigner’s Friend” thought experiment to explore the nature of measurement and to argue over whether objective facts can exist. That’s important because scientists carry out experiments to establish objective facts. But if they experience different realities, the argument goes, how can they agree on what these facts might be? That’s provided some entertaining fodder for after-dinner conversation, but Wigner’s thought experiment has never been more than that—just a thought experiment. There’s Growing Evidence That the Universe Is Connected by Giant Structures. Your Brain Hallucinates Your Conscious Reality.
Why Earth's History Appears So Miraculous. It was hard times for the bomber pilots that floated over Europe, their planes incinerating cities below, like birds of prey. Even as they turned the once-bustling streets beneath to howling firestorms, death had become a close companion to the crews of the Allied bombers as well. In fact, surviving a tour with the Bomber Command had become a virtual coin flip. While their munitions fell mutely from bomb bays, an upward sleet of fire from smoldering city grids and darkened farmland shot the planes out of the sky like clay pigeons. For recruits encountering the freshly empty bunk beds of dead airmen, morale was sapped before they could even get in the cockpit. Hoping to slow this attrition, Allied officers studied the pattern of bullet holes in returning aircraft for vulnerable parts to reinforce with armor.

President Trump's dismantling of environmental regulations unwinds 50 years of protections. In Trump's first two years in office, the Environmental Protection Agency's rate of deregulation was so high that an internal watchdog has said the agency "exceeded" its self-established goals. And in the third year of his presidency, agencies, not just the EPA, have continued the environmental regulation rollbacks. His administration has even moved to rollback some protections established under the 50-year-old Clean Air Act. Breaking away from environmental restrictions deemed cumbersome or unfair also became a global issue early in Trump's presidency, with his decision to pull out of the Paris climate accords -- an agreement among several countries to combat climate change.
Scientific experts, including members of the EPA's own scientific advisory board, have asserted that axing and altering these rules and regulations will be detrimental toward the environment.

Climate change will displace millions. Wildfires tearing across Southern California have forced thousands of residents to evacuate from their homes. Even more people fled ahead of the hurricanes that slammed into Texas and Florida earlier this year, jamming highways and filling hotels. A viral social media post showed a flight-radar picture of people trying to escape Florida and posed a provocative question: What if the adjoining states were countries and didn’t grant escaping migrants refuge?
By the middle of this century, experts estimate that climate change is likely to displace between 150 and 300 million people. If this group formed a country, it would be the fourth-largest in the world, with a population nearly as large as that of the United States.
