On land, Australia’s rising heat is ‘apocalyptic.’ In the ocean, it’s worse.: Washington Post

"The Washington Post’s examination of accelerated warming in the waters off Tasmania marks this year’s final installment of its global series “2C: Beyond the Limit,” which identified hot spots around the world. The investigation has shown that disastrous impacts from climate change aren’t a problem lurking in the distant future: They are here now. 

Nearly a tenth of the planet has already warmed 2 degrees Celsius since the late 19th century, and the abrupt rise in temperature related to human activity has transformed parts of the Earth in radical ways. 

In the United States, New Jersey is among the fastest-warming states, and its average winter has grown so warm that lakes no longer freeze as they once did. Canadian islands are crumbling into the sea because a blanket of sea ice no longer protects them from crashing waves. Fisheries from Japan to Angola to Uruguay are collapsing as their waters warm. Arctic tundra is melting away in Siberia and Alaska, exposing the remains of woolly mammoths buried for thousands of years and flooding the gravesites of indigenous people who have lived in an icy world for centuries. 

Australia is a poster child for climate change. Wildfires are currently raging on the outskirts of its most iconic city and drought is choking a significant portion of the country."

The terrible truth of climate change: The Monthly

"As I collated this information for my presentation, it became clear to me that Cyclone Tracy is a warning. Without major action, we will see tropical cyclones drifting into areas on the southern edge of current cyclone zones, into places such as south-east Queensland and northern New South Wales, where infrastructure is not ready to cope with cyclonic conditions.

These areas currently house more than 3.6 million people; we simply aren’t prepared for what is upon us.

There is a very rational reason why Australian schoolkids are now taking to the streets – the immensity of what is at stake is truly staggering. Staying silent about this planetary emergency no longer feels like an option for me either. Given how disconnected policy is from scientific reality in this country, an urgent and pragmatic national conversation is now essential. Other-
wise, living on a destabilised planet is the terrible truth that we will all face."


"We still have time to try and avert the scale of the disaster, but we must respond as we would in an emergency. The question is, can we muster the best of our humanity in time?"

What You Should Know About the New Climate Change Report: Medium

We have the technological capability to stop our earth from warming further. But it looks like that won’t happen.

"Even tiny increases in global temperature — give or take just 0.5°C — could severely alter our planet, bringing us hotter days year-round, the total destruction of the world’s corals, more dangerous flooding, and increased instances of drought and wildfire. Even though we have the technology and know-how to cap warming at a 1.5°C increase, humanity is on track to warm the planet by 3°C by the end of the century.

This is all according to a new report by a group of international researchers that advise the United Nations on all things climate change. The research zooms in on what would happen if the world warms by 1.5°C and 2°C above pre-industrial levels. The report’s authors say keeping temperature rise at or below 1.5°C is necessary to stave off the more drastic impacts of global climate change."

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 understood2,3

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."

The Age of Stupid revisited: what's changed on climate change?

Ten years after climate movie The Age of Stupid had its green-carpet, solar-powered premiere, we follow its director as she revisits people and places from the film and asks: are we still heading for the catastrophic future it depicted?

Earth at 2° hotter will be horrific. Now here’s what 4° will look like. | David Wallace-Wells





Big Think

This is what the world will be like if we do not act on climate change.

 - The best-case scenario of climate change is that world gets just 2°C hotter, which scientists call the "threshold of catastrophe". - Why is that the good news? Because if humans don't change course now, the planet is on a trajectory to reach 4°C at the end of this century, which would bring $600 trillion in global climate damages, double the warfare, and a refugee crisis 100x worse than the Syrian exodus. - 

David Wallace-Wells explains what would happen at an 8°C and even 13°C increase. These predictions are horrifying, but should not scare us into complacency. "It should make us focus on them more intently," he says. David Wallace-Wells is a national fellow at the New America foundation and a columnist and deputy editor at New York magazine. He was previously the deputy editor of The Paris Review. He lives in New York City. His latest book is The Uninhabitable Earth: Life After Warming (https://goo.gl/ih35YX

The (Australian) government thinks we’re idiots and is not serious about reducing emissions : The Guardian

Australia's shameful gas emissions record
Australia's gas comparative emissions 2016- Click to enlarge
"Tackling climate change is tough and Scott Morrison’s latest policy is an insult"

"This fund of $2bn over 10 years is not just a rebranding of Tony Abbot’s Direct Action, it is actually a diminishment of it. At $200m a year on average it is less than half the money a year that was spent on Direct Action – a policy that was so laughably bad that a government with any level of shame would quietly have dumped it and pretended it never happened.

Yet, here we are. Nine years after Lenore Taylor ripped apart

A dire opportunity: rural communities in the face of climate change: CRA

Another key element from all of the reports mentioned here is the need for negative emissions through soil health
Soil Health - Decarbonisation
"So, how far behind are we, and how much do these new reports change the conversation? In 2017, James Hansen, who is a native Iowan and one of the top climatologists in the world, published a report with some updated figures. We have already warmed the world beyond 1° C and have enough carbon dioxide in the atmosphere to commit ourselves to at least 1.3° C. To stay at or below 1.5° C would mean keeping atmospheric carbon dioxide concentration to 350 parts per million (ppm) or lower, hence the name of the activist group 350.org. We crossed the threshold of 400 ppm in 2013.

From Medium: The Economics of Climate Change Explained

Increased coastal storms due to climate change are expected to cause significant economic damage.
Increased coastal storms due to climate change are expected to cause significant economic damage.
"Climate change is well known for its destructive impacts — ranging from rising sea levels to more fierce natural disasters. There is increasing concern that some areas currently home to many people could become uninhabitable within only a few short decades. The world has come together in response, forming the Paris Agreement in an attempt to mitigate the effects of climate change.

The case for “conditional optimism” on climate change: Vox

"Yes, it’s going to get worse, but nobody gets to give up hope or stop fighting. Sorry."

"In sum: humanity faces the urgent imperative to reduce greenhouse gas emissions, then eliminate them, and then go “net carbon negative,” i.e., absorb and sequester more carbon from the atmosphere than it emits. It will face that imperative for several generations to come, no matter what the temperature is.


Yes, it’s going to get worse, but nobody gets to give up hope or stop fighting. Sorry.


Rather than just rejecting the question, though, let’s give it a little more specificity, so we can discuss some real answers. Let’s ask: What are the reasonable odds that the current international regime, the one that will likely be in charge for the next dozen crucial years, will reduce global carbon emissions enough to hit the 2 degree target?"

Siemens: What is climate change? Video


Now 2 degrees has been shown to be too high a limit. 1.5 degrees is what we must try for. 

"Climate Change is the bad news story that isn’t going away 

From heatwaves to hurricanes, from droughts to floods 

Extreme weather events are becoming more frequent, putting lives at risk Human activity is causing our climate to change 

The CO2 emissions from our cars, our industries and our power plants are heating up the planet 

To prevent further dangerous levels of climate change Countries around the world signed up to the Paris Agreement The Paris 

Agreement aims to keep global warming below 2 degrees To stop the planet getting warmer, we need to reduce the use of fossil fuels 

And increase the share of renewable energy, like from wind, solar and low carbon sources 

Climate action is everyone‘s responsibility: governments, businesses, communities, individuals 

The actions we can take to reduce our carbon footprint, like investing in green technologies can also reduce costs and create jobs The risks and costs of inaction are too high to ignore. 

So what are we waiting for? The time to act is now." Siemens Nov 3,  2017
