...[this is] not about youth activism. This is not about us... we don't want to be heard. We want the science to be heard."
Instead of submitting a personal statement... she sent Congress a major report on global warming along with eight sentences of her own.
"I am submitting this report as my testimony because I don't want you to listen to me," she said. "I want you to listen to the scientists. And I want you to unite behind the science. And then I want you to take action."
In some places, like Victoria in Australia, students and public workers are being actively encouraged to walk out of school and work.
"We want our kids to be engaged in the world around them, so we don't think it's fair to criticise students for holding a peaceful protest about an issue as important as this" [government spokesman to Melbourne-based newspaper].
Wetbulb temperatures of 35°C have not yet been widely reported, but there is some evidence that they are starting to occur in Southwest Asia. Climate change then offers the prospect that some of the most densely populated regions on Earth could pass this threshold by the end of the century, with the Persian Gulf, South Asia, and most recently the North China Plain on the front line. These regions are, together, home to billions of people.When regions cross the 35°C wetbulb limit, they will quite simply become uninhabitable by humans outside of air-conditioned environments. And we simply do not have sufficient power to air-condition that much of the world ... and trying to generate it will only make the problem worse unless we can do so using non-carbon-emitting means.
By 2050, cooling systems are expected to increase electricity demand by an amount equivalent to the present capacity of the US, EU, and Japan combined.Even then, that heat doesn't just go nowhere; remember, we cool buildings by moving the unwanted heat outside. The more we cool the inside, the hotter the outside gets. Which means we need to turn up the air conditioning to keep the building cool, dumping even more heat outside...
The first of Iceland’s 400 glaciers to be lost to the climate crisis will be remembered with a memorial plaque – and a sombre warning for the future – to be unveiled by scientists and local people next month.#GlobalWarming #ClimateChange #Glaciers #Environment #Iceland
The former Okjökull glacier, which a century ago covered 15 sq km (5.8 sq miles) of mountainside in western Iceland and measured 50 metres thick, has shrunk to barely 1 sq km of ice less than 15 metres deep and lost its status as a glacier.
Researchers from Rice University in Houston, Texas, a leading Icelandic author, Andri Snær Magnason, and the geologist Oddur Sigurðsson will lead the unveiling ceremony at the site in Borgarfjörður on 18 August, local media said.
“In the next 200 years, all our glaciers are expected to follow the same path,” the plaque reads, in Icelandic and English. “This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it.”
The memorial is dated August 2019 and also carries the words “415ppm CO2”, referring to the record-breaking level of 415 parts per million of carbon dioxide recorded in the atmosphere in May this year.
A century ago, a strain of pandemic flu killed up to 100 million people—5 percent of the world’s population. In 2013, a new mystery illness swept the western coast of North America, causing starfish to disintegrate. In 2015, a big-nosed Asian antelope known as the saiga lost two-thirds of its population—some 200,000 individuals—to what now looks to be a bacterial infection. But none of these devastating infections comes close to the destructive power of Bd—a singularly apocalyptic fungus that’s unrivaled in its ability not only to kill animals, but to delete entire species from existence.#Biology #Nature #Environment #FungalDisease #Amphibians #Disease
Bd—Batrachochytrium dendrobatidis in full—kills frogs and other amphibians by eating away at their skin and triggering fatal heart attacks. It’s often said that the fungus has caused the decline or extinction of 200 amphibian species, but that figure is almost two decades out-of-date. New figures, compiled by a team led by Ben Scheele from the Australian National University, are much worse.
Scheele’s team estimates that the fungus has caused the decline of 501 amphibian species—about 6.5 percent of the known total. Of these, 90 have been wiped out entirely. Another 124 have fallen by more than 90 percent, and their odds of recovery are slim. Never in recorded history has a single disease burned down so much of the tree of life. “It rewrote our understanding of what disease could do to wildlife,” Scheele says.
“There’s no obvious way to deal with this,” Lips says. Some researchers have set up captive-breeding programs to buy time for species in contaminated habitats. Others are looking at ways of manipulating the fungus, or breeding more tolerant frogs, or pairing the frogs with defensive bacteria, or relocating frogs to sites that are inhospitable to the fungus. None of these solutions is a silver bullet, and none is close to readiness. “It says a lot about the scary nature of the disease that even after intense, long-term collaborations we haven’t come up with a viable solution,” Lips adds."
