Republicans leaders should take their own advice, listen to climate scientists | Dana Nuccitelli | Environment. Republican presidential candidate Rick Santorum recently said we should “leave science to the scientists.” That’s good advice; especially since Republican Party leaders’ response when asked about climate change is inevitably “I’m not a scientist.” When it comes to questions of science, listening to scientific experts is always a good idea.

The problem is that in this case, Republican leaders are failing to follow their own advice. Rick Santorum denies the 97% climate consensus Santorum was a guest on the August 28th episode of the HBO show Real Time with Bill Maher, in which climate change was the primary topic of discussion. During the interview, Santorum made several false statements denying the 97% expert consensus on human-caused global warming. It’s important to remember that there have been numerous studies confirming this high level of expert consensus. PolitiFact contacted Verheggen and several other experts and rated this statement “False.” However, SO2 also causes acid rain. I believe in an authority greater than David Cameron’s. Am I an extremist? | Giles Fraser: Loose canon. The Church of England is the longest-running prevent strategy in history. If not from its inception, then certainly from the end of the English civil war, the big idea of the C of E was to prevent radicalisation – precisely the sort of radicalisation that led to religious people butchering each other throughout the 1630s and 40s.

Its strategy was to discourage two things: big expansive politically minded theology – the sort of theology that has ambitions to change the world – and religious passion (or “enthusiasm” as it was dismissively described). From the end of the 17th century, a new mood of religious inclusivity would dominate. Increasingly suspicious of theological dispute, the idea was to kill off God – or at least God-talk – with religion. People would all pray together, using the same form of words (the aptly described Book of Common Prayer), but be discouraged from discussing the ideological side of religion. Let me be clear. @giles_fraser. Emma Thompson joins protest at Shell’s London HQ – video.

Bushfires, heatwaves and early deaths: the climate is changing before our eyes | Tim Flannery | Environment. When I wrote The Weather Makers, I laid out the state of climate science as it was understood in 2005. The book received much acclaim, but it was also criticised by climate-change sceptics as extremist and alarmist. Since the book was published, the Intergovernmental Panel on Climate Change (IPCC) has completed two major summaries, in the form of its fourth and fifth assessment reports, and thousands of scientific publications have added to our understanding of how Earth’s climate system responds to carbon pollution. As a result, many details of climate science have been clarified. Not only are the scientific projections of major trends more certain than ever, but today many of us also have firsthand experience of living in a strongly shifted climate.

Despite their vast increase in computational power, the models remain consistent in telling us that our Earth is warming, and will continue to warm in proportion to the volume of fossil fuel we burn.

Climate Change Impacts. Humans Cross Another Danger Line for the Planet - Observations - Scientific American Blog Network. Five years go an impressive, international group of scientists unveiled nine biological and environmental “boundaries” that humankind should not cross in order to keep the earth a livable place. To its peril, the world had already crossed three of those safe limits: too much carbon dioxide in the atmosphere, too rapid a rate of species loss and too much pouring of nitrogen into rivers and oceans—primarily in the form of fertilizer runoff. Now we have succeeded in transgressing a fourth limit: the amount of forestland being bulldozed or burned out of existence (see map below). Less and less forest reduces the planet’s ability to absorb some of that carbon dioxide and to produce water vapor, crucial to plant life.

And the ongoing loss alters how much of the sun’s energy is absorbed or reflected across wide regions, which itself can modify climate. Disappearing Forests: Green are sustainable for now, yellow and red are past the safe limit. >>Want to know more? Rapid Arctic ice loss linked to extreme weather changes in Europe and US | Environment. The string of massive snowstorms and bone-chilling cold on the US east coast, as well as flooding in Britain and record temperatures in Europe, are linked to rapid ice loss in the Arctic, new research appears to confirm.

While the rapidly-thawing Arctic cannot be held responsible for specific weather events like the “snowmageddon” in 2009, Hurricane Sandy, or European heatwaves, researchers at Rutgers university said it appears to be a prime reason why the polar jet stream – a ribbon of winds that encircles the globe – gets ‘stuck’ with increasing frequency.

Western Europe and large parts of North America will experience more extreme weather because of “Arctic amplification” - the enhanced sensitivity of high latitudes to global warming, the team suggested in a paper published in the journal Philosophical Transactions of the Royal Society A. “We are seeing these extremes because the Arctic is warming faster than elsewhere. But the impacts could be substantial, they warn. Ited Nations and Climate Change.

Climate change: at last a breakthrough to our catastrophic political impasse? | Julia Powles and Tessa Khan. Today a group of eminent jurists accuse governments and enterprises of being in clear and flagrant breach of their legal obligations on climate change – under human rights law, international law, environmental law, and tort law. Human ravaging of our planet and climate through relentless fossil fuel extraction and greenhouse gas emissions is undoubtedly the defining existential challenge of our time. Our collective failure to commit to meaningful reductions in emissions is a political and moral travesty, with catastrophic implications, particularly for the poorest and most marginalised, domestically and globally. The dismal pace of international negotiations – and the prospect of yet more disappointment at the UN Paris conference in December – is why the Guardian has thrown its weight behind a divestment campaign, pressurising moral investors to take a stand against those responsible for the greatest emissions.

The Extinction Crisis. It’s frightening but true: Our planet is now in the midst of its sixth mass extinction of plants and animals — the sixth wave of extinctions in the past half-billion years. We’re currently experiencing the worst spate of species die-offs since the loss of the dinosaurs 65 million years ago. Although extinction is a natural phenomenon, it occurs at a natural “background” rate of about one to five species per year.

Scientists estimate we’re now losing species at 1,000 to 10,000 times the background rate, with literally dozens going extinct every day [1]. It could be a scary future indeed, with as many as 30 to 50 percent of all species possibly heading toward extinction by mid-century [2]. Unlike past mass extinctions, caused by events like asteroid strikes, volcanic eruptions, and natural climate shifts, the current crisis is almost entirely caused by us — humans. Species diversity ensures ecosystem resilience, giving ecological communities the scope they need to withstand stress.
