Sonne kühlt ab: Droht uns die kleine Eiszeit?

Die Sonne ist der Stern, der unsere Erde mit Wärme versorgt. Doch Wissenschaftler haben Anzeichen dafür gefunden, dass sich das Zentrum unseres Planetensystems für die nächsten 40 Jahre abkühlen könnte. Droht uns jetzt eine „kleine Eiszeit“?

UK Met Office: Fastest decline in solar activity since the last ice age

The past few decades have been characterized by a period of relatively high solar activity. However, the recent prolonged solar minimum and subsequent weak solar cycle 24 have led to suggestions that the grand solar maximum may be at an end. Using past variations of solar activity measured by cosmogenic isotope abundance changes, analogue forecasts for possible future solar output have been calculated. An 8% chance of a return to Maunder Minimum-like conditions within the next 40 years was estimated in 2010 (ref. 2)....

Griechenland erklärt erneuerbare Energie zu einer Gefahr für nationale Sicherheit

The new government’s policy shift away from renewable energies “is very clear” said Psomas. “All [the new government] is concerned with is how to promote power generation from fossil fuels e.g. new lignite power stations, new gas pipes and explanatory drilling for oil. So far, it has shown no interest at all for renewables energy” Psomas added. -

Since the end of January, when a new coalition government between a far left party and a populist right party came to power, the new Greek government is at war with many of Greece’s environmental non-governmental organisations (NGOs). The subject of the stormy relationship is the Greek government’s decision to give the final go ahead at Ptolemaida V, a 660 MW new power plant that burns lignite… Energy minister Lafazanis answers that Ptolemaida V [is] required since renewable...

Judith Curry: Die Klimadebatte in den USA

This is the text of a speech Prof Curry gave in the House of Lords on 15 June 2015: Good evening everyone, it’s a great pleasure to be here, and I would like to thank the GWPF for inviting me.Tonight I will be talking about the state of the climate debate in the US. This is a story of a sharp partisan divide between the Democrats and Republicans regarding what, if anything, we should do about climate change. Unfortunately, climate science is caught in the crossfire. Full text (pdf)

Am Tag danach, die große Ernüchterung

Calls by the Group of Seven (G7) Monday to slash world carbon emissions did little to boost UN climate talks in Bonn, where frustration mounted over the snail-­like progress. Due to end on Friday, the 11­day Bonn talks are tasked with shaping a draft text for the November 30 ­December 11 UN conference in Paris, which must yield a global agreement.

But after a week of wrangling, just about five percent had been shaved off a sprawling near ­90 ­page draft, mostly by removing glaring duplications, said delegates. And there has been little serious talk about some of the many thorny issues that remain.

G7: Mythos und Wirklichkeit

Mythos: Die „Klimakanzlerin“ Merkel blieb beharrlich: Die G 7 haben auf Schloss Elmau angekündigt, dass die Industriestaaten in Zukunft komplett auf Kohle, Öl und Gas verzichten wollen.  „Im Laufe dieses Jahrhunderts“ wollen sie ganz auf die Verbrennung von Braun- und Steinkohle, Öl und Gas verzichten. Unmissverständlich steht die Kohle als der größte Kohlendioxidemittent zuerst auf der Abschussliste.
Wirklichkeit: Five of the world’s seven richest countries have increased their coal use in the last five years despite demanding that poor countries slash their carbon emissions to avoid catastrophic climate change, new research shows. Britain, Germany, Italy, Japan and France together burned 16% more coal in 2013 than 2009 and are planning to further increase construction of coal-fired power stations.

Der Arktische Fehlschluss

London 8 June 2015. - A new paper from the Global Warming Policy Foundation accuses scientists of systematically misleading the public, saying that they are blaming changes in polar bear populations on global warming despite overwhelming evidence to the contrary.

In the paper ‘The Arctic Fallacy’, Dr Susan Crockford, an expert in Arctic mammals, notes that reductions in polar bear populations are clearly linked to thick spring ice, which reduces the availability of the bears’ prey. Despite this, scientists routinely blame reductions in summer ice, despite there being little evidence to support the idea: in fact years of low summer ice extent are often accompanied by big increases in bear populations. According to Dr Crockford, polar bear scientists are being `willfully blind to the facts’.

Professor Matthew Cronin of the...
