2013-07-22 Carbon Budgets and Switching to Renewables

This paper assembles a chain of evidence from the global Carbon Budget for permissible climate change to the choice of components of the solution based on their Energy Return on (Energy) Invested (EROI). It shows that for an 80% chance of limiting global warming to 2 C, only 565 GtCO2 can be emitted (up to 2050).

Growth in Japan’s solar power sector is predicted to slow over the coming decade, according to a new analysis from the Fitch Group, but not before the industry adds 17 gigawatts (GW) worth of new solar capacity between the end of 2017 and the end of 2020.

2003-04-15 The Future of the Hydrogen Economy: Bright or Bleak?

Ulf Bossel, Baldur Eliasson, and Gordon Taylor

I found on the Internet an early version of this paper, authored by Ulf Bossel and Baldur Eliasson. I had been doing desk research in the same general area, and offered a number of comments and contributions over a period of some months. Eventually I became a co-author of the final version, dated 2003-04-15.

2011-03-11 Fukushima - My Documents

On 2011-03-11, the Fukushima Daiichi nuclear power plant in Japan was damaged by a major earthquake and tsunami. The three operating reactors overheated, leading to hydrogen explosions and radioactive releases, which necessitated progressively wider evacuations of the populace. In the weeks that followed, it became clear that Reactors 1 to 3 and the spent fuel pools of Reactors 1 to 4 had the potential for far greater radioactive releases.

Urgent changes needed to cut risk of extreme heat, drought, floods and poverty, says IPCC

The world’s leading climate scientists have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C, beyond which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people.

The authors of the landmark report by the UN Intergovernmental Panel on Climate Change (IPCC) released on Monday say urgent and unprecedented changes are needed to reach the target, which they say is affordable and feasible although it lies at the most ambitious end of the Paris agreement pledge to keep temperatures between 1.5C and 2C.

The half-degree difference could also prevent corals from being completely eradicated and ease pressure on the Arctic, according to the 1.5C study, which was launched after approval at a final plenary of all 195 countries in Incheon in South Korea that saw delegates hugging one another, with some in tears.

“It’s a line in the sand and what it says to our species is that this is the moment and we must act now,” said Debra Roberts, a co-chair of the working group on impacts. “This is the largest clarion bell from the science community and I hope it mobilises people and dents the mood of complacency.”
