G-7-Gipfel Merkel hält USA für nicht mehr verlässlich

  • „Wir Europäer müssen unser Schicksal wirklich in unsere eigene Hand nehmen“, sagte die Kanzlerin.
  • Zuvor war ein Treffen der Industriestaaten-Gruppe G 7 auf Sizilien ohne greifbare Ergebnisse zu Ende gegangen.
  • Die Sechser-Gruppe hatte bei dem Gipfel vergeblich versucht, US-Präsident Donald Trump von den Chancen einer entschlossenen Klimapolitik zu überzeugen.

Bundeskanzlerin Angela Merkel setzt kein Vertrauen mehr in die transatlantischen Beziehungen. „Die Zeiten, in denen wir uns auf andere völlig verlassen konnten, die sind ein Stück vorbei“, sagte Merkel am Sonntag in München. „Das habe ich in den letzten Tagen erlebt.“ Die EU-Staaten müssten mehr als bisher für ihre eigene Zukunft kämpfen. „Wir Europäer müssen unser Schicksal wirklich in unsere eigene Hand nehmen“, sagte die CDU-Vorsitzende bei einem gemeinsamen Bierzelt-Auftritt mit CSU-Chef Horst Seehofer.

On Climate, Uncertainty Is Not the Same as Agnosticism

Greg Ip disagrees with Bret Stephens: uncertainty does not negate the case for climate action

Climate models generally assume the relationship between damage and temperature is nonlinear, that is each added degree of warming is more destructive than the last, Greg Ip writes.

Our former colleague Bret Stephens has stirred a hornet’s nest at his new home, The New York Times, with a column that challenged the certainty with which many climate-change activists make their case and compared them to Hillary Clinton’s hubristic campaign advisers.

But while I agree with his central point, I don’t agree with the implication: that uncertainty negates the case for policy action. Yes, religious conviction is too often attached to the apocalyptic scenarios embedded in many climate forecasts. A freak weather event such as a warm April or Superstorm Sandy often becomes a clarion call to action, when science doesn’t support the link. Den Rest des Beitrags lesen »

Climate-change sceptics will shrug but such reactions are profoundly misguided. They just don’t give a damn

Subject: The Arctic as it is known today is almost certainly gone

On current trends, the Arctic will be ice-free in summer by 2040

THOSE who doubt the power of human beings to change Earth’s climate should look to the Arctic, and shiver. There is no need to pore over records of temperatures and atmospheric carbon-dioxide concentrations. The process is starkly visible in the shrinkage of the ice that covers the Arctic ocean. In the past 30 years, the minimum coverage of summer ice has fallen by half; its volume has fallen by three-quarters. On current trends, the Arctic ocean will be largely ice-free in summer by 2040.

Climate-change sceptics will shrug. Some may even celebrate: an ice-free Arctic ocean promises a shortcut for shipping between the Pacific coast of Asia and the Atlantic coasts of Europe and the Americas, and the possibility of prospecting for perhaps a fifth of the planet’s undiscovered supplies of oil and natural gas. Such reactions are profoundly misguided. Never mind that the low price of oil and gas means searching for them in the Arctic is no longer worthwhile. Or that the much-vaunted sea passages are likely to carry only a trickle of trade. The right response is fear. The Arctic is not merely a bellwether of matters climatic, but an actor in them.

The current period of global warming that Earth is undergoing is caused by certain gases in the atmosphere, notably carbon dioxide. These admit heat, in the form of sunlight, but block its radiation back into space, in the form of longer-wavelength infra-red. That traps heat in the air, the water and the land. More carbon dioxide equals more warming—a simple equation. Except it is not simple. A number of feedback loops complicate matters. Some dampen warming down; some speed it up. Two in the Arctic may speed it up quite a lot. Den Rest des Beitrags lesen »

Trump’s indifference to climate change has not changed China’s view

Once a foot-dragger, it now wants to lead

RESIDENTS have found something else to blame for the toxic smog that envelops many Chinese cities for much of the year. Until recently the culprits that were usually fingered were the obvious ones: emissions from coal-fired power plants, exhaust fumes from cars and dust from building sites. This year, however, reports began to appear in state-run media that climate change is now reckoned to be a factor, too. Chinese scientists say that in eastern China global warming is resulting in less rain and wind to clear the pollutants. The government’s weather bureau illustrated its online account of the discovery with a picture of zombie-looking figures in hazmat suits shrouded by haze.

America’s president, Donald Trump, may have little interest in climate change: Wilbur Ross, his commerce secretary, said the subject was “not a major part of the discussion” when Mr Trump met his Chinese counterpart, Xi Jinping, at Mar-a-Lago, Florida, earlier this month. But in China the government, and increasingly the public, see it as a real danger, responsible for rising sea levels that threaten coastal cities as well as for aggravating droughts in the north, floods in the south and, as it now turns out, the omnipresent smog. Some people wonder whether Mr Trump’s indifference might reduce China’s willingness to take action against climate change. Why bother if the second-biggest emitter of greenhouse gases appears to have lost faith in the cause? Fortunately, there is no sign that China, the biggest emitter, is wavering.

To Curb Global Warming, Science Fiction May Become Fact

Not according to Trump! (hfk)

The Stein glacier in Switzerland in 2015. Scientists and photographers are returning to the world’s glaciers, and watching them shrink with each visit.

Remember “Snowpiercer”?

In the delirious sci-fi thriller by the Korean director Bong Joon-ho, an attempt to engineer the climate and stop global warming goes horribly wrong. The planet freezes. Only the passengers on a train endlessly circumnavigating the globe survive. Those in first class eat sushi and quaff wine. People in steerage eat cockroach protein bars.

Scientists must start looking into this. Seriously.

News about the climate has become alarming over the last few months. In December, startled scientists revealed that temperatures in some parts of the Arctic had spiked more than 35 degrees Fahrenheit above their historical averages. In March, others reported that sea ice in the Arctic had dropped to its lowest level on record. A warming ocean has already killed large chunks of Australia’s Great Barrier Reef.

UMGANG MIT UNBEQUEMEN WAHRHEITEN

Posted by hkarner - 6. April 2017

FURCHE-Kolumne 206, Wilfried Stadler


Unbequeme Wahrheiten kann man entweder zur Kenntnis nehmen oder verdrängen. Eine dritte Möglichkeit ist, sie einfach für unwahr zu erklären. Das funktioniert allerdings nicht auf dem Weg einer sachlichen Widerlegung durch anders geartete Fakten. Viel verlässlicher wirkt die Diskreditierung derer, die sie verbreiten.
Wie das geht, führt uns ein auch in Ökologie-Fragen wild um sich twitternder US-Präsident vor. Das Problem des menschengemachten Klimawandels sei, so behauptet er, nichts als eine Erfindung Chinas, das sich damit einen Wettbewerbsvorteil gegenüber dem durch Klima-Rücksichtnahmen in seinem Wachstum gehemmten Westen verschaffen will. Sein Umweltminister Scott Pruitt, ein ehemaliger Lobbyist der Erdölindustrie und dezidierter Gegner alternativer Energien, dreht eilfertig die ökologische Uhr zurück. Der „Clean Power Plan“ zur Begrenzung der Treibhausgasemissionen ist bereits außer Kraft gesetzt. Als nächstes soll das Pariser Klima-Abkommen aufgekündigt werden. Den Rest des Beitrags lesen »
