Here are the last four feature articles from Giles Parkinson at RenewEconomy (as of last weekend):
It’s quite likely that politicians don’t read RenewEconomy. Here’s Ben Potter in the last Weekend AFR:

Or it may be God with climate scientist on her side. Whichever, Katharine Hayhoe is one smart lady. A New Scientist interview (no doubt pay-walled) caught my interest.
There is a longer interview at Carbon Brief which rewards reading. She’s one of the most informed, balanced and insightful climate scientists I’ve come across. Continue reading Climate scientist with God on her side
In 1988 James Hansen gave his famous testimony to the US Senate. For the short story, go to Tamino at Open Mind. For the longer story, Gavin Schmidt at RealClimate, plus the commentary thread is best.
Hansen told the politicians that our production of greenhouse gases, principally CO2, N2O, CH4 and CFC, were warming the climate. He said temperatures would go up in the coming years: Continue reading Hansen got it right
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.

A new study has found that Antarctic ice loss and sea level rise rates have tripled since 2012.
This assessment involves 84 scientists from more than 40 institutions, and combines data from 24 satellite surveys. It follows in the footsteps of the first IMBIE (Ice Sheet Mass Balance Inter-comparison Exercise) conducted in 2012, and paints a particularly grim picture of the years between then and 2017. Continue reading Antarctic ice loss rates have tripled since 2012
1. Climate as an existential threat
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
Back in February this year Malcolm Turnbull (acting for the Commonwealth Government, of course) stumped up $60 million to future proof the Reef. Now we have Great Barrier Reef gets funding boost as PM tells ‘doomsayers’ to be optimistic. Via the NY Times and Gizmodo There’s $500 million more now to save the Great Barrier Reef:
including $200 million in funding to reduce agricultural pollution and $100 million for “reef restoration and adaptation,” which includes a project to grow stronger corals in laboratories. Other projects include killing off invasive species like the crown-of-thorns starfish and community engagement and enforcement
Everyone, except the ABC, is telling Turnbull, that’s fine and dandy, but won’t do much good unless we get serious about climate change. Continue reading Saving the Great Barrier Reef – seriously?
1. Warming could soon exceed 1.5°C
The UK Met Office has warned that temperatures could break through the 1.5°C threshold within five years.
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.
The UN Environment Program in its annual emissions gap report, published last October, said government commitments were only a third of what was needed. Continue reading Climate clippings 222
Last Monday the ‘cosmic ray’ theory of climate change struck again when Amanda Vanstone at ABC RN’s Counterpoint found:
Climate change may be largely caused by solar events, letting humans off the hook, claims Danish researcher Henrik Svensmark.
It has been a standard myth, debunked at Climate Skeptic. Now Svensmark and others have conducted new research published in Nature, which got this billing at Science News:
The missing link between exploding stars, clouds, and climate on Earth
Breakthrough in understanding of how cosmic rays from supernovae can influence Earth’s cloud cover and thereby climate

a 2015 study found there is no techno-fix to prevent a catastrophic collapse of ocean life for centuries if not millennia if we continue current CO2 emissions trends through 2050.
A study published in May 2017 tells us that oxygen is depleting in the oceans two or three times faster than expected.
From Think Progress:
by combining oxygen loss with ever-worsening ocean warming and acidification, humans are re-creating the conditions that led to the worst-ever extinction, which killed over 90 percent of marine life 252 million years ago.

Back in 2003 a heatwave centred in France killed over 70,000 people. Another which struck Moscow in 2010 killed 10,000. During the 2009 Black Saturday bushfires in Victoria 173 people tragically lost their lives from the fire. However, health authorities believe Victoria’s record-breaking heatwave may have contributed to the deaths of about another 374 people with the state’s death toll 62% higher than at same time in the previous year.
The elderly were worst affected, but the very young and those in frail health are also typically affected in events like this. Continue reading Sizzling summers presage a global future
This is the first of several posts which will show that climate change is becoming a real and present danger.
