Nature Communications: Warming assessment of the bottom-up Paris Agreement emissions pledges

"Tightening the warming goal of each country’s effort-sharing approach to aspirational levels of 1.1 °C and 1.3 °C could achieve the 1.5 °C and well-below 2 °C-thresholds, respectively. 

This new hybrid allocation reconciles the bottom-up nature of the Paris Agreement with its top-down warming thresholds and provides a temperature metric to assess NDCs. When taken as benchmark by other countries, the NDCs of India, the EU, the USA and China lead to 2.6 °C, 3.2 °C, 4 °C and over 5.1 °C warmings, respectively."

The Guardian: Policies of China, Russia and Canada threaten 5C climate change, study finds

"Ranking of countries’ goals shows even EU on course for more than double safe level of warming."

"China, Russia and Canada’s current climate policies would drive the world above a catastrophic 5C of warming by the end of the century, according to a study that ranks the climate goals of different countries.
The US and Australia are only slightly behind with both pushing the global temperature rise dangerously over 4C above pre-industrial levels says the paper, while even the EU, which is usually seen as a climate leader, is on course to more than double the 1.5C that scientists say is a moderately safe level of heating.

The study, published on Friday in the journal Nature Communications, assesses the relationship between each nation’s ambition to cut emissions and the temperature rise that would result if the world followed their example."

UTS Science in Focus: Will coral reefs survive climate change?

University of Technology Sydney

Published on Sep 6, 2018  With Dr Emma Camp

 

The world’s coral reefs are under threat. Environmental changes such as warming waters and pollution are causing ocean acidification, coral disease and coral bleaching. 

 

Australia’s world heritage listed, the Great Barrier Reef is no exception. At UTS, our marine scientists have been studying reef forming corals and coral reef fishes to better understand how environmental stressors and climate change will affect reefs—and the marine life they support.

Inside EPA head Andrew Wheeler’s highly effective campaign to sacrifice public health in favor of the fossil-fuel industry

The President’s Coal Warrior

If you could design the ideal character to assure the continuing domination of Big Coal and Big Oil in America and to reaffirm their faith in their God-given right to cook the climate in pursuit of profit, that character would look a lot like acting EPA Administrator Andrew Wheeler.

ABC: Australia's biggest oil and gas producer Woodside is now calling for a carbon price.

Key points:

• Woodside boss Peter Coleman says the time for Australia to act on climate change is now
• Woodside has joined other resource giants BHP and Rio Tinto in calling for change
• Mr Coleman says individual companies may help change broader corporate resistance to a carbon price 

Speaking on the ABC's The Business, chief executive Peter Coleman said the time to act on climate change was now.
"We need a price on carbon, we need to ensure that the most effective energy gets into the system," he said.

New UN report outlines ‘urgent, transformational’ change needed to hold global warming to 1.5°C

"Whether we are successful primarily depends on the rate at which government and non-state bodies take action to reduce emissions. Yet despite the urgency, current national pledges under the Paris Agreement are not enough to remain within a 3℃ temperature limit, let alone 1.5℃.

Global warming is not just a problem for the future. The impacts are already being felt around the world, with declines in crop yields, biodiversity, coral reefs, and Arctic sea ice, and increases in heatwaves and heavy rainfall. Sea levels have risen by 40.5mm in the past decade and are predicted to continue rising for decades, even if all greenhouse emissions were reduced to zero immediately. Climate adaptation is already needed and will be increasingly so at 1.5℃ and 2℃ of warming."

The Guardian: The Earth is in a death spiral. It will take radical action to save us

Illustration: Ben Jennings

By George Monbiot, November 14  2018

Climate breakdown could be rapid and unpredictable. We can no longer tinker around the edges and hope minor changes will avert collapse.

 Public figures talk and act as if environmental change will be linear and gradual. But the Earth’s systems are highly complex, and complex systems do not respond to pressure in linear ways. When these systems interact (because the world’s atmosphere, oceans, land surface and lifeforms do not sit placidly within the boxes that make study more convenient), their reactions to change become highly unpredictable. Small perturbations can ramify wildly. Tipping points are likely to remain invisible until we have passed them. We could see changes of state so abrupt and profound that no continuity can be safely assumed.
