German Chancellor Angela Merkel is battling to prevent US President Donald Trump undermining the world leaders' united front on climate change. At the Paris climate deal, all world leaders spoke in favour of limiting global temperature rise to 2 degrees but that was after a massive diplomatic effort by President Barack Obama made membership of the climate club a moral imperative. He and the French hosts created such an atmosphere that even the normally foot-dragging Russians and Saudis committed to the deal, despite their long history of slowing progress in climate negotiations behind the scenes. They own vast fossil fuel...

Greenland just set the record for coldest July temperature ever reported in the Northern Hemisphere at -33C. Climate experts immediately responded to the record cold by saying Greenland is melting faster than expected at -33C.

On Thursday's New Day on CNN, during a discussion of President Donald Trump's speech in Poland, CNN international correspondent Christiane Amanpour at one point hinted that those who are "denying climate science" are similar to those who used to think the planets and sun revolve around the Earth as she recalled Trump's decision to pull the U.S. out of the Paris Accord. After recounting that Trump had praised former Polish president Lech Walesa and recalled his anti-communist activities from the 1980s, Amanpour noted that Trump had also mentioned the Polish scientist Copernicus and his contributions to astronomy: (VIDEO-AT-LINK) On Copernicus...

Penn State climate scientist, Michael ‘hockey stick’ Mann commits contempt of court in the ‘climate science trial of the century.’ Prominent alarmist shockingly defies judge and refuses to surrender data for open court examination. Only possible outcome: Mann’s humiliation, defeat and likely criminal investigation in the U.S. The defendant in the libel trial, the 79-year-old Canadian climatologist, Dr Tim Ball (above, right) is expected to instruct his British Columbia attorneys to trigger mandatory punitive court sanctions, including a ruling that Mann did act with criminal intent when using public funds to commit climate data fraud. Mann’s imminent defeat is set...

Gov. Jerry Brown of California on Thursday reinforced his reputation as America’s de facto leader on climate change, announcing to cheering crowds in Hamburg, Germany that his state would gather leaders from around the world for a global warming summit next year. Speaking by videoconference to the Global Citizens Festival in Hamburg, where President Donald Trump is joining other world leaders for the Group of 20 economic summit, Governor Brown said the president “doesn’t speak for the rest of America” in pulling out of the Paris agreement on climate change.

Way, way back in April 2017, scientists around the world participated in the ‘March for Science’ as a show of force and unity against an allegedly anti-science Trump administration. Their motto was “science not silence”: many wrote that mantra on pieces of duct tape and stuck it across their mouths. March for Science organizers claimed that “the best way to ensure science will influence policy is to encourage people to appreciate and engage with science". But that was so three months ago. Many scientists are now rejecting an open debate on anthropogenic global warming. EPA administrator Scott Pruitt appears ready...

U.S. President Donald Trump arrived for a G20 summit in Hamburg on Thursday risking isolation on climate policy and the wrath of anti-capitalist protesters threatening to disrupt the meeting of the world's leading economic powers. Trump, who paused to wave as he descended the steps of Air Force One with his wife Melania, faces a testy confrontation with leaders of the other big G20 economies after deciding last month to pull the United States out of the 2015 Paris climate deal. Trade policy is another area of contention at the summit, which protesters have vowed to disrupt. "Welcome to Hell"...

Hopes that the world’s huge carbon emissions might not drive temperatures up to dangerous levels have been dashed by new research. The work shows that temperature rises measured over recent decades do not fully reflect the global warming already in the pipeline and that the ultimate heating of the planet could be even worse than feared. How much global temperatures rise for a certain level of carbon emissions is called climate sensitivity and is seen as the single most important measure of climate change. Computer models have long indicated a high level of sensitivity, up to 4.5C for a doubling...

... Imagine, if you will, that you spend your entire professional life trying to do one thing to the best of your ability. In my case, that one thing is to study the nature and causes of climate change. You put in a long apprenticeship. You spend years learning about the climate system, computer models of climate and climate observations. You start filling a tool kit with the statistical and mathematical methods you’ll need for analyzing complex data sets. After decades of seeking to advance scientific understanding, reality suddenly shifts, and you are back in the cold darkness of ignorance....

Berlin, Jul 4 (AFP) German Chancellor Angela Merkel’s scientist-husband will take leaders’ spouses at a G20 summit, including Melania Trump, to a climate research centre amid a bitter row over global warming. Joachim Sauer, who usually shuns publicity, will take the visiting dignitaries sightseeing through Hamburg on a river cruise and to the spectacular new Elbphilharmonie concert house. But the quantum chemist has also insisted they stop off at the German Climate Computing Centre — an itinerary point sure to put the spotlight on the US First Lady after President Donald Trump in June pulled out of the 2015 Paris...

Guest essay by David ArchibaldFrom a post a couple of days ago: “an F10.7 flux above 100 causes warming and below that level causes cooling.” Greg asked “Can you prove that?” I already had in this WUWT post from 2012. But it is worth revisiting the subject because it answers the big question – If all the energy that stops the Earth from looking like Pluto comes from the Sun, what is the solar activity level that corresponds to our average climate? Because solar activity is falling and climate will follow.As Nir Shaviv observed, the oceans are a big...

Full headline: HAWK AND DOVE Stephen Hawking fears Trump could ‘push Earth over the brink’ and start chain reaction which wipes out humanity. In recent years, Hawking has become something of a doom-monger who is determined to sketch out a variety of grim fates which await the human race. In his latest prophecy, the professor suggested our planet could be destined to become totally uninhabitable. “We are close to the tipping point where global warming becomes irreversible. Trump’s action could push the Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, and...

The first official trailer for An Inconvenient Sequel: Truth to Power was released on Tuesday. The timing of the clip's release comes at a crucial point for climate change discussion, with its release coming the same day Donald Trump signed an executive order to rescind Obama's Clean Power Plan and a host of other climate-related regulations.

During the last ice age, too little atmospheric carbon dioxide almost eradicated mankindGuest Essay by Dennis T. AveryAside from protests by Al Gore, Leonardo Di Caprio and friends, the public didn’t seem to raise its CO2 anguish much above the Russians-election frenzy when Trump exited the Paris Climate Accords.Statistician Bjorn Lomborg had already pointed out that the Paris CO2 emission promises would cost $100 trillion dollars that no one has, and make only a 0.05 degree difference in Earth’s 2100 AD temperature. Others say perhaps a 0.2 degree C (0.3 degrees F) difference, and even that would hold only...

Former President Barack Obama took a shot at his successor while traveling in Indonesia, saying President Trump had caused a "temporary absence of American leadership" on climate policy. "In Paris, we came together around the most ambitious agreement in history to fight climate change," Obama said Saturday, per Bloomberg. "[A]n agreement that even with the temporary absence of American leadership will still give our children a fighting chance." Trump withdrew the United States from the Paris climate agreement, months after Obama's team raced to finalize an international climate accord before he left office. That decision angered Democratic leaders, although Trump...

Presented at World Federation of Scientists, Erice, Sicily, 20 August 2015 This is a version of the talk I gave about uncertainty in the global average air temperature record at the 48th Conference of the World Federation Scientists on “Planetary Emergences and Other Events,” at Erice, Sicily, in August of 2015. It was a very interesting conference and, as an aside, for me the take home message was that the short-term emergency is Islamic violence while the long-term emergency is some large-scale bolide coming down. Please, however, do not distract conversation into these topics. Abstract: I had a longer abstract,...

German Chancellor Angela Merkel has vowed confrontation with President Donald Trump over the Paris climate agreement when the two meet up at next month’s G-20 summit in Hamburg, Germany. In a speech to the German parliament Thursday, Merkel said that the European Union would push ahead with tackling the problem of climate change, even without the help of the United States. “Since the withdrawal of the U.S. [from the Paris climate accord], we’re more determined than ever that this be a success,” Merkel said, reports Deutsche Welle. “We can't wait for the last man on Earth to be convinced by...

RUSH: This from the U.K. Independent. “World Has Three Years to Prevent Dangerous Climate Change, Warn Experts — Since the 1880s, the world’s temperature has risen by about 1C because of greenhouse gases resulting from human activity.” Do you know what happened off the coast of North Carolina this week? Well, I don’t know if it actually happened this week. It was discovered this week. You know what happened? A new island. A new sandbar just popped up out of nowhere. It’s next to a known island, but out of nowhere they noticed there’s a brand-new — and it’s not...

The sun is heading into a period known as solar minimum, during which activity at the surface will ‘change form.’In this time, certain types of activity, such as sunspots and solar flares will drop – but, it’s also expected to bring the development of long-lived phenomena including coronal holes. According to NASA, solar minimum could also enhance the effects of space weather, potentially disrupting communications and navigation systems, and even causing space junk to ‘hang around.’
