UN meeting failure, so what now?

56 Comments

This is the final version of a post first published on Thursday 26 September. This version contains additional material, and a considerable amount of the earlier version has been pruned.

I hope to do a specific post on the UN Climate Action Summit in New York. Meanwhile we have a closing media release from the summit. While it tells us that “77 countries committed to cut greenhouse gas emissions to net zero by 2050, [and] while 70 countries announced they will either boost their national action plans by 2020 or have started the process of doing so”, none of the large emitters were included. Matt McDonald, Associate Professor of International Relations at the The University of Queensland, gives a neat summary with lots of links in Highly touted UN climate summit failed to deliver – and Scott Morrison failed to show up.

One success of the Summit was Greta Thunberg’s amazing speech:

Greta Thunberg “We’ll be watching you!”

The urgency of now

In 1988 James Hansen addressed the US Senate warning of the danger of climate change. Ostensibly the world took notice in the Earth Summit at Rio and the establishment of the UNFCCC (UN Framework Convention on Climate Change) which meets in the Conference of Parties for two weeks in early December each year. It gave us the Kyoto Protocol and the Paris Agreement. However, as I indicated in Four graphs that matter in the climate emergency: bonus edition, the effect on rising CO2 emissions is invisible:

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

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

This is an updated version earlier post, slightly shorter, where I have deleted some material in favour of new material, especially towards the end, and sharpening some points along the way.

1. Waiting for Godot

Part of my delay in completing this week’s edition was waiting for something that wasn’t ridiculous to happen. There is plenty like Boris Johnson suspending parliament, and Trump attacking Fox News, and Fox News hitting back.

To be honest, I’ve been knocked a bit askew by the David Spratt’s question At 4°C of warming, would a billion people survive? The answer according to some respected scientists is, in brief, probably not, something less than a billion, and 4°C seems to be where we are heading.

That would mean on average more than a million deaths from global warming each week for the next 90 years. Continue reading Weekly salon 1/9 →

Climate action: a doddle or deep adaptation?

18 Comments

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.

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 →

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

18 Comments

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

15 Comments

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

4 Comments

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 →
