The approaching crisis: Is the world running out of water?

news.com.au / Nick Whigham / 17 June 2017

Water is absolutely fundamental to life, which makes the increasingly loud warnings about water scarcity and an impending global water crisis so concerning for world leaders.

If current patterns of consumption continue unabated, two-thirds of the world’s population will be facing water shortages as a daily reality by 2025 and global policy makers are scrambling to avoid catastrophe.

“What’s happening bit by bit is that water scarcity is becoming increasingly common all around the world, no matter where you look as country after country hits the limit of what it can use,” says Professor Mike Young.

“Whether that’s in Australia, California, China, India, Pakistan, or right throughout Africa.”

Surviving a hostile climate on local food: Michael Brownlee

Conversation Earth / Dave Gardner / 06 June 2017

A scaled-up local food system may be the only way we can feed ourselves as we weather the storm of climate change. Until now, CSAs, urban gardens and farmer’s markets have been the face of the local food movement. But Michael Brownlee, author of The Local Food Revolution: How Humanity Will Feed Itself in Uncertain Times, tells us this is not nearly enough. In this episode, the first of a two-part conversation, Brownlee shares how global industrial agriculture is failing us, and can’t adapt to the coming climate changes. He advocates relocalizing our food supply chain in order to adapt and survive.

Antarctic ice loss 2002-2016

NASA Climate Change / 19 May 2017

These images, created with GRACE data, show changes in Antarctic ice mass since 2002. Orange and red shades indicate areas that lost ice mass, while light blue shades indicate areas that gained ice mass. White indicates areas where there has been very little or no change in ice mass since 2002. In general, areas near the center of Antarctica experienced small amounts of positive or negative change, while the West Antarctic Ice Sheet experienced a significant ice mass loss (dark red) over the fourteen-year period. Floating ice shelves whose mass GRACE doesn’t measure are colored gray.

Arctic stronghold of world’s seeds flooded as permafrost melts

The Guardian / Damian Carrington / 19 May 2017

The vault is on the Norwegian island of Spitsbergen and contains almost a million packets of seeds, each a variety of an important food crop. When it was opened in 2008, the deep permafrost through which the vault was sunk was expected to provide “failsafe” protection against “the challenge of natural or man-made disasters”.

But soaring temperatures in the Arctic at the end of the world’s hottest ever recorded year led to melting and heavy rain, when light snow should have been falling. “It was not in our plans to think that the permafrost would not be there and that it would experience extreme weather like that,” said Hege Njaa Aschim, from the Norwegian government, which owns the vault.

April of 2017 was second hottest in 137 year climate record

RobertScribbler.com / 17 May 2017

According to measurements by NASA’s GISS global temperature monitoring service, April of 2017 was considerably warmer than all past Aprils in the climate record with the single exception of 2016.

The month came in at 0.88 degrees Celsius above NASA’s 20th Century baseline and fully 1.1 degrees Celsius above 1880s averages. This measure was just 0.01 C warmer than now third warmest 2010 and 0.18 C shy of last year’s record. All of the top ten hottest Aprils on record have occurred since 1998 and six of the top ten hottest Aprils have occurred since 2010.

New book ranks the top 100 solutions to climate change

Vox / David Roberts / 10 May 2017

By now, the looming dangers of climate change are clear to anyone who’s been paying attention, covered extensively in both academic literature and the popular press.

But what about solutions?

For all the hand-wringing on climate change over the years, discussion of solutions remains puzzlingly anemic and fractured. A few high-profile approaches, mainly around renewable energy and electric cars, dominate discussion and modeling. But there’s been no real way for ordinary people to get an understanding of what they can do and what impact it can have. There remains no single, comprehensive, reliable compendium of carbon-reduction solutions across sectors.

At least until now.

The Transition Framework

Resilience is the ability of a system or community to withstand impacts from outside. An indicator is a good way of measuring that. Conventionally, the principal way of measuring a reducing carbon footprint is CO2 emissions. However, we firmly believe that cutting carbon while failing to build resilience is an insufficient response when you’re trying to address multiple shocks such as peak oil, climate change and the economic crisis together.
