Du déni, jusque quand ?

Is the climate consensus 97%, 99.9%, or is plate tectonics a hoax? Four years ago, my colleagues and I published a paper finding a 97% consensus in the peer-reviewed literature on human-caused global warming.

Is the climate consensus 97%, 99.9%, or is plate tectonics a hoax?

Since then, it’s been the subject of constant myths, misinformation, and denial. In fact, last year we teamed up with the authors of six other consensus papers, showing that with a variety of different approaches, we all found the expert consensus on human-caused global warming is 90–100%. Most of the critiques of our paper claim the consensus is somehow below 97%. For example, in a recent congressional hearing, Lamar Smith (R-TX) claimed we had gone wrong by only considering “a small sample of a small sample” of climate studies, and when estimated his preferred way, it’s less than 1%. But in a paper published last year, James Powell argued that the expert consensus actually higher – well over 99%.

Scientists try to replicate climate denier findings and fail. Does the Ted Cruz in you ever wonder whether global warming really is just a hoax?

Scientists try to replicate climate denier findings and fail

Whether skeptics really are the Galileos of our time? Whether climate scientists really do just want to make money? Well, wonder no more. A group of researchers just tried to replicate 38 peer-reviewed studies that support skeptic talking points, and surprise! They ran into some trouble. In a paper published last week in the journal Theoretical and Applied Climatology, the researchers reported a number of problems with the 38 studies, including questionable physics and incomplete data sets. One of the most common problems the researchers encountered was something called “cherry-picking.” Dana Nuccitelli, one of the coauthors of the study, gave an example of such cherry-picking in an article he wrote for the Guardian. Another state bans agency from discussing climate change. This story is reproduced here as part of the Climate Desk collaboration.

Another state bans agency from discussing climate change

The climate change language police just struck again. Last month, it was in Florida, where former staffers with the state’s Department of Environmental Protection alleged that senior officials, under the direction of Gov. Rick Scott (R), had instituted an unwritten ban on using the phrases “climate change” and “global warming.” Scott denied the claim. Facebook. Paris2015 : Genève ne sauvera pas la mise.

Paris2015 : Genève ne sauvera pas la mise

Les mécanismes techniques toujours plus sophistiqués sont déconnectés de la réalité des dérèglements climatiques et des populations qui en subissent les conséquences. Et ils ne permettent pas de neutraliser les tensions politiques, ni de solutionner la crise climatique. À Lima, les États ont refusé de revoir à la hausse leurs engagements d’ici 2020 comme le préconisent les scientifiques. Au prétexte de la prise en compte des nouveaux (des)équilibres géopolitiques, les pays les plus puissants de la planète essaient de restreindre la portée des principes d’équité et de responsabilités communes mais différenciées.

L’échelon national prime désormais dans la définition des contributions nationale, comme si l’objectif commun visant à rester en deçà des 2 °C de réchauffement global avait été abandonné. The Senate will vote to decide if climate change is real. Senate Majority Leader and honorary fifth ninja turtle Mitch McConnell announced yesterday that he will graciously allow the Senate to vote on climate change.

Specifically: thing or not a thing? Here at Grist, we understand that plenty of things that seem real might not be real (Drake, cake pops), and vice versa (ghosts). Even Australia is joining the climate fight. The prime minister of Australia is called Abbott.

Australia has been named the worst-performing industrial country in the world on climate change in a report released at international negotiations in Peru.

The climate change performance index ranked Denmark as the best-performing country in the world, followed by Sweden and Britain. Among the world’s top 10 emitters, Germany was ranked the highest at 22. Australia was second bottom overall, above Saudi Arabia — which was not classified as industrial. The report states: “The new conservative Australian government has apparently made good on last year’s announcement and reversed the climate policies previously in effect.

As a result, the country lost a further 21 positions in the policy evaluation compared to last year, thus replacing Canada as the worst-performing industrial country.” China, the world’s biggest emitter, was in 45th spot — one below the U.S., which is the world’s second largest emitter of greenhouse gases that cause climate change. In the ski business, there are no climate deniers. Snow sport season may be officially upon us, but don’t get too excited yet.

In the ski business, there are no climate deniers

Some of California’s most beloved ski runs are looking pretty brown, making opening days a little less celebratory and a lot more troubling for skiers and snowboarders hoping to hit the slopes across the Golden State. According to research from the University of California, Berkeley’s Central Sierra Snow Lab near Lake Tahoe, last year’s snow pack was the second lowest it’s been in a whopping 90 years, topping just 52 inches.

Yes, we can beat climate change — but it will take massive international government coordination. One of my recurring obsessions over the years has been the enormous difference between reducing carbon emissions and reducing carbon emissions enough.

Yes, we can beat climate change — but it will take massive international government coordination

There are thousands of ways to reduce emissions relative to a business-as-usual baseline, many of which are relatively painless. But reducing emissions enough to limit temperature rise to 2 degrees Celsius — the agreed-upon international target — is another matter entirely. Plenty of policies and strategies can achieve the former but not the latter. It’s troubling how often this distinction is elided, especially in politics, where people talk as though reducing emissions at all, or even growing emissions more slowly, is a sign of success on climate change. That’s why, to my mind, some of the most important work in the world is being done at the Deep Decarbonization Pathway Project (DDPP). First and most importantly, the team at DDPP believes that meeting the 2C target is possible. Climat: les lenteurs et contradictions de la politique américaine - Page 2.

China to limit carbon emissions for first time, climate adviser claims. China, the world's biggest greenhouse gas emitter, will limit its total emissions for the first time by the end of this decade, according to a top government advisor.

China to limit carbon emissions for first time, climate adviser claims

He Jiankun, chairman of China's Advisory Committee on Climate Change, told a conference in Beijing on Tuesday that an absolute cap on carbon emissions will be introduced. "The government will use two ways to control CO2 emissions in the next five-year plan, by intensity and an absolute cap," Reuters reported He as saying. Though not a government official, He is a high level advisor. However, Jiankun later in the day appear to row back on the comments. "What I said today was my personal view. While environmentalists broadly welcomed his initial remarks, they cautioned that it was far from clear at what level the cap would be set and said it needed to be enforceable. China's emissions have risen dramatically in the last two decades, overtaking those from the US – the previous biggest producer – in 2006.

Climat: l'âge de la pénombre. Preventing climate change and adapting to it are not morally equivalent. Climate hawks are familiar with the framing of climate policy credited to White House science advisor John Holdren, to wit: We will respond to climate change with some mix of mitigation, adaptation, and suffering; all that remains to be determined is the mix. It’s a powerful bit of language.

It makes clear that not acting is itself a choice — a choice in favor of suffering. But in another way, Holdren’s formulation obscures an important difference between mitigation (reducing greenhouse gas emissions to prevent climate effects) and adaptation (changing infrastructure and institutions to cope with climate effects). It makes them sound fungible, as though a unit of either can be traded in for an equivalent unit of suffering.

That’s misleading. Carbon is global, adaptation is local With every ton of carbon we emit, we add incrementally to the total concentration of greenhouse gases in the atmosphere.

Climate change sceptics are 'headless chickens', says Prince Charles. The Prince of Wales has launched an attack on climate change sceptics, describing them as the "headless chicken brigade" and accusing "powerful groups of deniers" of engaging in intimidation. Charles, who has long campaigned to raise awareness of global warming and has hit out at sceptics in the past, unleashed his latest salvo during an awards ceremony at Buckingham Palace for green entrepreneurs. "It is baffling, I must say, that in our modern world we have such blind trust in science and technology that we all accept what science tells us about everything - until, that is, it comes to climate science," the prince said in a speech on Thursday evening. "All of a sudden, and with a barrage of sheer intimidation, we are told by powerful groups of deniers that the scientists are wrong and we must abandon all our faith in so much overwhelming scientific evidence.

This chart makes it painfully obvious that climate deniers are ridiculous. Suriname MP urges adoption of environment law drafted by citizens' group. A house flooded by heavy downpours that inundated parts of Suriname earlier this year.

It's Time to Stop Portraying Climate Change as a 'Debate' The science forum on reddit, the self-described “front page of the Internet,” is now a climate change denial-free zone — which means it’s now a paradise. OK, that might be overstating things. But the atmosphere of the science subreddit has improved remarkably since the moderators started cracking down.

According to one of the forum’s moderators, nothing — not evolution, not vaccines — drew the kind of vitriol and ill-informed soliloquies as climate change: Some issues, however, are particularly contentious.
