Climate action: a doddle or deep adaptation?

Again, this post started as an edition of Climate clippings.

Where I ended up after a series of happenings as described below, is concluding that we need a paradigm shift in our climate change aspirations. Instead of trying to limit warming to a point where we can avoid dangerous climate change, we need to recognize that we’ve already gone too far, that the climate is already dangerous, so we should aim to ratchet down GHG concentrations in the atmosphere to attain a safe climate.

Saudis throw a spanner

At a mid-year meeting of UNFCCC in Bonn this year in June a small group of countries led by Saudi Arabia have put the kybosh on any formal consideration of the IPCC Special Report on 1.5°C in the UNFCCC forum. Continue reading Saudis throw a spanner

Four graphs that matter in the climate emergency

First graph

Greta Thunberg, the girl who can’t quit, said:

    The emissions are increasing and that is the only thing that matters.

This is what was shown for July 01, 2019 at Muana Loa:

Freak hail in Guadalajara, Mexico

With France breaking heat records by nearly 2°C and 1.5 metres of hail fall on Guadalajara in Mexico, Australian blog Lethal Heating has been blogging a storm on the climate emergency. LH selects and republishes three articles per day, adding value by making some available that may be paywalled, and adding a list of links to relevant previously published articles.

Below I’ve linked to some recent articles. Continue reading Climate clippings 232: climate emergency edition

Climate emergency – the next (political) step

Greta Thunberg, the girl who can’t quit, was asked to talk to the billionaire entrepreneurs in Davos:

    “I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act,” she told them.

She also said:

    The emissions are increasing and that is the only thing that matters.

Labor needs to rethink the climate emergency

I pinched that cartoon from the Townsville Bulletin from Facebook, where it was doing the rounds. I think it’s tragic rather than funny, but may go some way to explain why Labor, in Queensland and federally, is over-reacting to the ‘message’ that was sent on Adani, and the prospect of jobs flowing from the resources industry as against climate change and saving the planet. Both Queensland and federal Labor appear to be caving in to coal interests, and both appear to be clueless about the urgency of the climate emergency.

Cloud tipping point could yield a cataclysmic 14°C warming

Commonly 2°C has been seen as the threshold for dangerous climate change, although last year the IPCC report on 1.5°C revealed that at that lower level we enter a zone where tipping points may take us to 4°C and beyond.

Levels of 4°C threaten civilisation as we know it. At 6°C we worry about the survival of the human race. However, at that point Tapio Schneider and his team at the California Institute of Technology, Pasadena, have found that there may be a further tipping point which heats the planet another 8°C to make it 14°C above pre-industrial levels (New Scientist, so probably pay-walled.)

How is this so? Continue reading Cloud tipping point could yield a cataclysmic 14°C warming

Climate change by the numbers

In 1999 NASA lost its $125-million Mars Climate Orbiter because spacecraft engineers failed to convert from Imperial to metric measurements when exchanging vital data before the craft was launched. Numbers are important!

When Michael Le Page attempts to sort out the numbers in climate science (probably pay-walled) it’s not as straight forward as you might think. For starters we are given this image:

When ice melts, sea level rises – but how much, and how fast? Paul Nicklen/National Geographic Creative

Sorry, when floating ice melts the sea level does not rise. The caption is misleading. Continue reading Climate change by the numbers

Our legacy to the children

Last week school children of Australia marked the card of the Morrison government on climate change and gave it a fail. Was this too harsh?

On Q&A last Monday a Melbourne boy called Marco asked the panel:

    “I’m greatly concerned about my future and the future of children all around the world who will suffer the consequences of climate change more than anyone else,” Marco said.

    “A few days ago thousands of students from around Australia, like me, went on strike from school to demand that the Government acts on climate change.

    “When will the Government start to care about my future and children around the world by acting on climate change and create a strong climate policy?”

Cool patch below Greenland is bad news

Two years ago this month I posted Global temperature, the North Atlantic cool patch and the Gulf Stream. The cool patch was still there, lasting throughout the 2018 northern summer:

This now needs to be recognised as an enduring feature associated with the slowdown of the overturning ocean circulation AMOC (Atlantic Meridional Overturning Circulation) which James Hansen and Makiko Sato say is having an effect on the east coast hurricanes which have been so prominent during this summer.

Trouble at the top of the world

Arctic summer sea ice minimum was the sixth lowest on record. So we can all relax, right?

Wrong.

I’ll come back to that. However, Tamino at Open Mind points out that while the Arctic warms three to four times as fast as global warming, the Arctic winters are warming at a much faster rate.

Using the NASA data, which is about mid-range in the major players, Tamino finds that the overall average warming rate since 1985 in the Arctic, at 6.48°C/century is fully 3.4 times as fast as the global rate since 1985 of 1.90°C/century. Continue reading Trouble at the top of the world
