Former US vice president Al Gore has produced a follow-up to his award-winning 2006 documentary, An Inconvenient Truth.

‘Human fingerprint’ found on global extreme weather

The Guardian / Damian Carrington / 27 March 2017

The fingerprint of human-caused climate change has been found on heatwaves, droughts and floods across the world, according to scientists.

The discovery indicates that the impacts of global warming are already being felt by society and adds further urgency to the need to cut carbon emissions. A key factor is the fast-melting Arctic, which is now strongly linked to extreme weather across Europe, Asia and north America.

Rising greenhouse gases in the atmosphere have long been expected to lead to increasing extreme weather events, as they trap extra energy in the atmosphere. But linking global warming to particular events is difficult because the climate is naturally variable.

Climate change pushing world into ‘uncharted territory’

The Guardian / Damian Carrington / 21 March 2017

2016 saw the hottest global average among thermometer measurements stretching back to 1880. But scientific research indicates the world was last this warm about 115,000 years ago and that the planet has not experienced such high levels of carbon dioxide in the atmosphere for 4m years.

2017 has seen temperature records continue to tumble, in the US where February was exceptionally warm, and in Australia, where prolonged and extreme heat struck many states. The consequences have been particularly stark at the poles.

The devastating impact of flying on the environment

The Conversation / Roger Tyers / 11 January 2017

Ready to get over your post-festive comedown by booking an escape to the sun? For many of you, that will involve flying. And while I’m sorry to put a downer on your holiday plans, there are several problems with this from a climate perspective.

The first is that aviation is essentially a fossil fuel industry, one which guzzles an eye-watering 5m barrels of oil every day. Burning that fuel currently contributes around 2.5% to total carbon emissions, a proportion which could rise to 22% by 2050 as other sectors emit less.

The second problem is, as Air Asia puts it, “Now everyone can fly”. And in “generation easyJet”, those who already fly, fly more than ever. This increasing demand from new and existing travellers means the number of passenger aircraft in our skies is set to double by 2035.

The third problem is that unlike other sectors where there might be a greener alternative (solar not coal, LEDs not lightbulbs etc), there is currently no way to fly 8m people every day without burning lots of dirty kerosene.

First climate model, age 50, predicted AGW almost perfectly

Forbes / Ethan Siegel / 15 March 2017

Modeling the Earth’s climate is one of the most daunting, complicated tasks out there. If only we were more like the Moon, things would be easy. The Moon has no atmosphere, no oceans, no icecaps, no seasons, and no complicated flora and fauna to get in the way of simple radiative physics. No wonder it’s so challenging to model! In fact, if you google “climate models wrong“, eight of the first ten results showcase failure. But headlines are never as reliable as going to the scientific source itself, and the ultimate source, in this case, is the first accurate climate model ever: by Syukuro Manabe and Richard T. Wetherald. 50 years after their groundbreaking 1967 paper, the science can be robustly evaluated, and they got almost everything exactly right.

Official trailer: Obselidia

Vimeo / Diane Bell / 2010

Winner of two awards at Sundance and nominated for two Independent Spirit Awards, Diane Bell’s ravishingly beautiful debut feature OBSELIDIA tells the story of lonely George, a man out of step with the 21st century who is writing an encyclopedia of obsolete things. On his quest to catalogue endangered occupations, he meets Sophie, a cinema projectionist at a silent movie theater, and together they journey to the desert of Death Valley to interview a maverick climate scientist who is predicting the eminent end of the world. Part road movie, part love story, OBSELIDIA is an intelligent, thought-provoking bittersweet meditation on loss and how we live with it – given that everything we love is going to end.

The Transition Framework

The Transition Towns movement aims toward veering away from excessive consumption – to deal with the conjoined problems of peak oil and climate change – but also in the belief that we may create an essentially more contented society, through building strong and resilient local communities. We will get to know our neighbours better, because we shall all need one another in the time to come.
