There are lots of tipping points in ecosystems and the climate, and many are interconnected. That means the massive changes we are wreaking will have many unexpected consequences. Continue reading Climate clippings 229→
1. Unsubsidised wind and solar now cheapest form of bulk energy
That is the case in all major economies except Japan, according to BNEF. From RenewEconomy:
The latest report says the biggest news comes in the two fastest growing energy markets, China and India, where it notes that “not so long ago coal was king”. Not any more.
“In India, best-in-class solar and wind plants are now half the cost of new coal plants,” the report says, and this is despite the recent imposition of import tariffs on solar cells and modules. Continue reading Climate clippings 228→
That was the headline in the dead tree version of the AFR. Bill Ferris is the outgoing Science and Innovation Australia chair. He says he didn’t find the Coalition government’s rewriting of the ACCC report to support coal-fired power a helpful signal, but:
what I am seeing – and you see it in the US as well – is that business and state governments are getting on with alternative energy sources, mainly renewables and storage,” said Mr Ferris, a veteran venture capitalist.
The last Climate clippingswas on July 2. Time to get back on the bike. Unfortunately this edition is not full of good news, apart from the prospect of eating the carcasses and droppings of bacteria feeding on hydrogen (see # 5). Next time I’ll try to catch up with some climate action.
1. Rising: Dispatches from the New American Shore, by Elisabeth Rush
A review by Dave Hage at Star Tribune of Elizabeth Rush’s new book Rising: Dispatches from the New American Shore says it is “a lovely and thoughtful book, so lyrical that you forget how much science it delivers.”
Rush, who teaches creative nonfiction at Brown University, has chosen to examine climate change through the lens of American places and people devastated by rising seas and higher temperatures. Reading her book is like learning ecology at the feet of a poet rather than a scientist.
Last September I half-finished a post on this topic, with a paper by David Spratt and Ian Dunlop as the centre-piece. Their 28-page report on the state of climate science, action and politics entitled What lies beneath? The scientific understatement of climate risks is introduced as a post at Climate Code Red, but I suggest you go directly to the paper itself. Read any part of it, and I can promise you will be alarmed. Continue reading Climate clippings 223→
The 1.5C threshold was set at Paris as an ambitious target because scientists fear that a world warmer than that would be susceptible to ever wilder climactic events that in turn would precipitate greater drought, habitat loss, food insecurity and mass migration.
A hundred kilometres of kelp forests off the western coast of Australia were wiped out by a marine heatwave between 2010 and 2013, a new study has revealed.
About 90% of the forests that make up the north-western tip of the Great Southern Reef disappeared over the period, replaced by seaweed turfs, corals, and coral fish usually found in tropical and subtropical waters. Continue reading Climate clippings 120→
The Weatherill and Koutsantonis strategy is to embrace new technologies, cheap wind and solar and storage, smart software and smarter management, and put into practice the sort of scenarios envisaged by the CSIRO, Energy Networks Australia and more recently by the storage review commissioned by chief scientist Alan Finkel.
