Alaska's in The Middle of a Record-Breaking Spring Melt, And It's Killing People: WP

From Science Alert

Bryan Thomas doesn't want any more "wishy-washy conversations about climate change." For four years, he has served as station chief of the Barrow Atmospheric Baseline Observatory, America's northernmost scientific outpost in its fastest-warming state.

Each morning, after digging through snow to his office's front door, Thomas checks the preliminary number on the observatory's carbon dioxide monitor. On a recent Thursday it was almost 420 parts per million - nearly twice as high as the global preindustrial average.

It's just one number, he said. But there's no question in his mind about what it means.

Alaska is in the midst of one of the warmest springs the state has ever experienced - a transformation that has disrupted livelihoods and cost lives.

Large potential reduction in economic damages under UN mitigation targets: Nature IJS

"International climate change agreements typically specify global warming thresholds as policy targets¹, but the relative economic benefits of achieving these temperature targets remain poorly understood^2,3. 

Uncertainties include the spatial pattern of temperature change, how global and regional economic output will respond to these changes in temperature, and the willingness of societies to trade present for future consumption. 

Here we combine historical evidence⁴ with national-level climate⁵ and socioeconomic⁶ projections to quantify the economic damages associated with the United Nations (UN) targets of 1.5 °C and 2 °C global warming, and those associated with current UN national-level mitigation commitments (which together approach 3 °C warming⁷)."

Is the Australian coalition government suggesting we shouldn’t try to limit global warming to below two degrees?

The cost of doing nothing about climate change

"Not explicitly, but it is worth asking. 

One of the odd things about the Coalition’s analysis is that it is partly based on a World Bank-backed study that found global carbon prices in 2030 would need to be between US$50 and US$100 to limit global warming to two degrees. But it doesn’t acknowledge that the Coalition has also committed to the two degrees goal (and more) by signing the Paris agreement.

Should we also assume the equivalent of up to a US$100 carbon price under Coalition policies? Or is it walking away from its commitment to Paris?

Media reporting often focuses on the cost of climate policy while ignoring the other side of the equation – the cost of doing nothing. Several studies have suggested it is significant.

A paper in the journal Nature estimated warming of between two and a half and three degrees could cut per-capita economic output by between 15% and 25% this century. Four degrees would be worse again.

This sort of scenario is increasingly being considered and factored in by insurers and long-term investors, who say they want action to avoid it. Whether political leaders and newspaper editors are listening is another question."

‘You did not act in time’: Greta Thunberg’s full speech to MPs: The Guardian

"Now we probably don’t even have a future any more.

Because that future was sold so that a small number of people could make unimaginable amounts of money. It was stolen from us every time you said that the sky was the limit, and that you only live once.

You lied to us. You gave us false hope. You told us that the future was something to look forward to. And the saddest thing is that most children are not even aware of the fate that awaits us. We will not understand it until it’s too late. And yet we are the lucky ones. Those who will be affected the hardest are already suffering the consequences. But their voices are not heard."

Our leaders are ignoring global warming to the point of criminal negligence. It's unforgivable : The Guardian

"The problem – and it’s an existential threat both profound and perverse – is that those who lead us and have power over our shared destiny are ignoring global warming to the point of criminal negligence. Worse than that, their policies, language, patronal obligations and acts of bad faith are poisoning us, training citizens to accept the prospect of inexorable loss, unstoppable chaos, certain doom. Business as usual is robbing people of hope, white-anting the promise of change. That’s not just delinquent, it’s unforgivable."

"It’s time to make sharp demands of our representatives, time to remove those who refuse to act in our common interest, time to elect people with courage, ingenuity and discipline, people who’ll sacrifice pride, privilege and even perks for the sake of something sacred. Because there’s something bigger at stake here than culture wars and the mediocrity of so-called common-sense. It’s the soil under our feet, the water we drink, the air we breathe."

Bill de Blasio Seeks to Flood-Proof Lower Manhattan by Adding Land: Bloomberg

"New York Mayor Bill de Blasio proposed a $10 billion plan to push out the lower Manhattan coastline as much as 500 feet, or two city blocks, to protect from flooding that’s expected to become more frequent as global temperatures rise.

The project would protect the South Street Seaport and the Financial District, along the eastern edge of lower Manhattan, an area just 8 feet (2.4 meters) above the water line, de Blasio said. Portions of the extended land would be at 20 feet above sea level. The city can’t build flood protection on the existing land because it’s too crowded with utilities, sewers and subway lines, he said.

Climate change: Sir David Attenborough warns of 'catastrophe': BBC

"Sir David Attenborough has issued his strongest statement yet on the threat posed to the world by climate change. 

In the BBC programme Climate Change - The Facts, the veteran broadcaster outlined the scale of the crisis facing the planet.

Sir David said we face "irreversible damage to the natural world and the collapse of our societies".

But there is still hope, he said, if dramatic action to limit the effects is taken over the next decade. 

• What is climate change?
• Talk to our climate change bot
• Central banks warn of climate dangers
• Warning from 'Antarctica's last forests'

Sir David's new programme laid out the science behind climate change, the impact it is having right now and the steps that can be taken to fight it.

"In the 20 years since I first started talking about the impact of climate change on our world, conditions have changed far faster than I ever imagined," Sir David stated in the film."
