The planet has changed. This is Iceland’s Skaftafellsjokull glacier in 1989 and 2020:
As reported in Al Jazeera, Christiana Figueres, one of the architects of the Paris Agreement, was stunned speechless when:
She was told by leading climate scientist Johan Rockström, the director of the Potsdam Institute for Climate Impact Research, that we have already gone beyond some key tipping points. Losing the resilience of the planet was the nightmare that is keeping scientists awake at night, Rockström said.
He was referring to (1) the Arctic summer sea ice (2) West Antarctic glaciers, and (3) tropical coral reef systems. Continue reading Climate tipping points: real and present
Ask yourself a simple question. Can you give hope to future generations that the Great Barrier Reef will be protected if your policy is to limit warming to 1.5°C when the GBR is already disappearing before our eyes?
With about 1.1°C of warming we are told that Unprecedented fires in California and Australia signal the dawn of the ‘fire age’. Richard Flanagan talks of a Tasmanian rainforest burnt in 2018, now desolate shale with no sign of regrowth.
As I write, pristine Fraser Island is burning on a front about 46 km long, with reports that water from water bombers is evaporating before it hits the ground.
We have now reached a point where the cost of insurance alone in flood and bushfire-prone communities makes it impossible to live there.
Dangerous climate change is already here.
How can we set a target of 1.5°C temperature (actually a 50% chance of limiting the increase to that level) when we know that during the Eemian interglacial sea levels rose 6-9 metres with 300ppm of CO2, and we have already broken through the 410 ppm? Continue reading Our beds are burning
Much of the talk about climate action focusses on renewable energy and electric cars. The latest National Greenhouse inventory gives the following pie chart by sector:
Few have addressed the entire problem, not even the IPCC, until Paul Hawken, of Natural Capitalism fame, set to work.
Back in June John D sent me the link to the Vox article A new book ranks the top 100 solutions to climate change. The results are surprising with an exhortation Definitely a must read for anyone interested in doing something about climate change. Late, but here it is. Hawken says that if we carry on as we are in a realistically vigorous manner, we will fail. We can succeed, he says, if we adopt and optimise all the solutions available to us, with technology that already exists. Continue reading Paul Hawken’s Drawdown a ‘must read’
