Mountain glaciers are essential water sources for nearly a quarter of the global population. But figuring out just how much ice they hold – and how much water will be available as glaciers shrink in a warming world – has been notoriously difficult. In a new study, scientists mapped the speed of over 200,000 glaciers to get closer to an answer. They discovered that widely used estimates of glacier ice volume may be off by about 20% in terms of how much Earth’s glaciers outside the Greenland and Antarctic ice sheets could contribute to sea level rise. Mathieu Morlighem, a leader in ice sheet modeling and a coauthor of the study, explains why the new results hold a warning for regions that rely on glaciers’ seasonal meltwater, but barely register in the big picture of rising seas.
December discussion at the American Geophysical Union suggested that the massive Thwaites glacier in Antarctica, the size of Florida, could plop into the ocean in the next 10 years, with the potential to set in train further collapses, raising sea level by as much as six feet. Thwaites itself could raise the level by two feet. A two meter sea level rise is half of everything the UN scientists in the IPCC report were expecting by the end of the century, which means they likely were way too conservative. One thing they could not foresee is that the South Pole has heated up 3 times as fast as other areas on earth in recent decades.
Should all West Antarctica’s glaciers ever collapse, there is no coastal city in the world that would not, over time, be swamped at ruinous cost to life and economies. The consensus of glaciologists used to be that it would take centuries of global heating before glaciers the size of Thwaites shattered and collapsed, but so rapid and unexpected has been the loss of sea ice at the opposite end of the earth in the Arctic, and so sudden was the loss of Larsen B that it is now considered possible it could happen rapidly in Antarctica, too. Ice loss in the Arctic barely affects sea levels because it mostly forms at sea. Antarctic ice, however, is mostly on land so any melting adds to sea levels.
My thought for the day Science has made in my lifetime, the most staggering achievements and they are embraced, recognised and enjoyed by all sections of society. The only areas that I can think of where science is questioned is in the religious fever of climate change doubters, conservative politics and unconventional religious belief.( John Lord )
Each cubic metre of lunar regolith contains 1.4 tonnes of minerals on average, including about 630 kilograms of oxygen. NASA says humans need to breathe about 800 grams of oxygen a day to survive. So 630kg oxygen would keep a person alive for about two years (or just over). Now let’s assume the average depth of regolith on the Moon is about ten metres, and that we can extract all of the oxygen from this. That means the top ten metres of the Moon’s surface would provide enough oxygen to support all eight billion people on Earth for somewhere around 100,000 years. This would also depend on how effectively we managed to extract and use the oxygen. Regardless, this figure is pretty amazing! Having said that, we do have it pretty good here on Earth. And we should do everything we can to protect the blue planet — and its soil in particular — which continues to support all terrestrial life without us even trying.
The greatest shame looking back is that it wasn’t science that put us 50-60 years back and behind the 8 ball. It wasn’t science that misinformed us and restricted our work on Climate. Its’ not science that is screwing us with Covid either.
After early psychiatric experimentation in the 1950s and ‘60s, followed by decades of prohibition – sparked in part by the backlash against the hippy counterculture – psychedelics are experiencing a renaissance. A new wave of research has returned to hallucinogenic drugs as potential candidates to treat psychiatric conditions.
We have to stop living in the past, teach science properly in all schools, let people follow any beliefs they choose – as long as they do not harm others in so doing – and teach ethics in all schools, while the money saved from ceasing to give tax benefits to existing bodies – except for genuinely philanthropic activities – should be used to help all the people who are currently struggling to survive. Far more important than religion, is ensuring that all can survive, and that demands attention to climate change!
The Australian Christian Lobby has called on its supporters not to “fear death” and instead push state governments to end COVID-19 lockdowns and restrictions. In an email to members on Friday night, managing director Martyn Iles said the coronavirus was here to stay and that he was “not afraid to face the inevitable”. “Christians should lead the way on this because fear of death’s a condition from which Christ has freed us,” Mr Iles wrote. “The truth is, we must face the virus, either sooner or later because it’s not going anywhere. But fear is ruling the day at great cost.
It may well be the case but in “reality” it still exists and need to be called out and eradicated
The idea of “race” still matters in sociology only because racist oppression still exists. But, since the mapping of the human genome, biologically, the term is irrelevant, writes Dr A L Jones.
Climate action advocates reiterated demands for urgent measures to rein in global heating after the World Meteorological Organization warned Thursday that there’s a 40% chance the planet will temporarily hit 1.5°C of warming in the next five years. The WMO, a United Nations agency, also said in its update that there’s a 90% chance at least one year between 2021 and 2025 will be the hottest on the books—a record currently held by 2016.

By undermining humanities education, the Morrison Government is helping create a superficial society, which opens the door to far-Right extremism, writes Alex Hipgrave.

More than 250 scientists and scholars from 30 countries have issued an open letter calling on policymakers to “engage more with the growing risk of societal disruption and collapse due to damage to the climate and environment,” arguing that only then “might communities and nations begin to prepare and so reduce its likelihood, speed, severity, harm to the most vulnerable, and to nature.”As World Teeters on Brink, Over 250 Scientists and Scholars Warn of Full-Fledged ‘Societal Collapse’ | Common Dreams News
There are voluntary redundancies going on left right and centre. For people who rely on research funding, I think this is the final straw.” University of Western Australia genetic disease researcher Dr Gina Ravenscroft found herself shaking as she read the grant results, on which the employment of her colleagues depended. “It is not a way to live, where you are so worked up and stressed about whether or not you’re going to be able to keep employing people,” she said. “There is just no way that is a sustainable way to fund research.”Coronavirus Australia: Scientists face bleak Christmas as COVID-19 funding crunch hits research

Whilst Australia has halted declining research funding, Federal funding policy has made it far more difficult for younger scientists to gain experience and stable employment. This is the fourth story in our series exploring intergenerational inequity. Lachlan Gray reports.
I recall back in 2014, during my second year of university, I was told by my lecturer to get out of Australia if I wanted any sort of career in science. At that time, and indeed now, that sentiment has continued to be relevant. Since the election of Tony Abbott in 2013, Australia has witnessed a dramatic decline in meaningful scientific funding from each successive Coalition government.
It’s what China understands and turns to offer global assistance and what the US and Australian ultra conservatives ignore with their early calls of back to work while they social distance (ODT)
While the politicians offer reassurance, the scientists urge vigilance. And it is worth heeding the science. The medical experts who advise the government expect this threat to continue in waves for years.
Even if we eradicate the disease in Australia, says James McCaw of the Doherty Institute and the University of Melbourne, the virus will spread around the world and easily return.
“That epidemic in some places may also go locally extinct after a small or a large wave,” he says. “But it’s almost implausible to imagine this virus going extinct globally, which means that it will be here to stay. It will become a part of our everyday life and the transition to it not being a huge driver of complete societal change is a very difficult thing to work through.”

Meanwhile, Columbia University’s Silencing Science Tracker documents news stories about climate scientists who have been discouraged from conducting, publishing or otherwise communicating scientific research. These groups have documented four ways that climate-related information has become less accessible since Trump took office.
If I do not support the 95% of scientists, every major scientific institution and the research that is constantly peer evaluated I am obliged to accept the alternative. That is that I should take seriously the likes of Andrew Bolt (a journalist), Alan Jones (I’m not sure how you would describe his contribution to society), Lord Monckton (a discredited something who was once a lobbyist for the tobacco companies), Nick Minchin and Tony Abbott (both politicians). In fact, Minchin is on the record as saying that climate change is a left-wing conspiracy to replace communism. None of the aforementioned people has a background or expertise in climate science.

India recently launched a “mini space shuttle” for just $14 million. Many people commented, expressing their unhappiness at India investing in space travel while so many of their people live in poverty. The space industry is worth more than a hundred billion dollars worldwide. Most of this is dominated by just a few countries. If India can break into this industry at a lower cost, it could provide a massive stimulus to their economy.
And let’s take a look at a few of the things that were more expensive than their latest launch, shall we?
Climate scientists have long been pressed to answer the question “did climate change cause this?” in the days following the most recent devastating weather event. A watershed report (pdf) released Thursday helps those scientists to more conclusively answer: “yes.” The report, authored by the Washington, D.C.-based National Academies of Sciences, Engineering, and Medicine (NASEM), outlines a system to determine which extreme weather events are caused by climate change and to what extent.
