A new study found adjustments made to global surface temperature readings by scientists in recent years “are totally inconsistent with published and credible U.S. and other temperature data.” “Thus, it is impossible to conclude from the three published [global average surface temperature (GAST)] data sets that recent years have been the warmest ever – despite current claims of record setting warming,” according to a study published June 27 by two scientists and a veteran statistician. The peer-reviewed study tried to validate current surface temperature datasets managed by NASA, NOAA and the UK’s Met Office, all of which make adjustments to...

Turkey’s President Recep Erdogan admits the only reason for being in the Paris Climate Treaty was to get money from the U.S. and other more wealthy nations.  Now that the U.S. has pulled out of the treaty, there’s no reason to expect the financial benefits. Proving yet again, for the eleventyth time, that the entire construct of the Paris Climate Treaty had nothing to do with the actual climate (ie. weather), and everything to do with economic wealth distribution. (Reuters)  The U.S. decision to pull out of the Paris climate agreement means Turkey is less inclined to ratify the deal...

A new scientific paper contends the entire foundation of the man-made global-warming theory – the assumption that greenhouse gases warm the atmosphere by trapping heat – is wrong. If confirmed, the study’s findings would crush the entire “climate change” movement to restrict CO2 emissions, the authors assert Some experts contacted by WND criticized the paper, while others advised caution. Still others suggested that the claimed discovery represents a massive leap forward in human understanding – a “new paradigm.” The paper argues that concentrations of CO2 and other supposed “greenhouse gases” in the atmosphere have virtually no effect on the earth’s...

Climate change is real and persistent. Even a brief study of the recent past illustrates this, but it becomes all the more certain when one broadens the scope to take in the vast sweep of geologic time. Is nature’s inherent dynamism responsible for the climate change of our era? Or are the cause(s) man-made?

G20 leaders agreed on condemning violence by demonstrators in Hamburg but were less united in their opinions on climate change and free trade. Bernd Riegert reports from Hamburg. Host Angela Merkel made a special appearance at the very end of the G20 summit, when she spoke to police representatives. She thanked them for putting their own safety on the line to ensure the security of heads of state and government and their delegations while they met in the Hanseatic city. The German chancellor was unambiguous in her strong condemnation of the violent clashes that militant anti-globalists had engaged in over...

HAMBURG (Reuters) - Leaders from the world's leading economies broke with U.S. President Donald Trump on climate policy at a G20 summit on Saturday, in a rare public admission of disagreement and blow to multilateral cooperation. German Chancellor Angela Merkel, keen to show off her skills as a mediator two months before a German election, achieved her primary goal at the meeting in Hamburg, convincing her fellow leaders to support a single communique with pledges on trade, finance, energy and Africa. But the divide between Trump, elected on a pledge to put "America First", and the 19 other members of...

New York City Mayor Bill de Blasio (D) on Saturday pushed back on President Trump’s decision to pull the U.S. out of the Paris climate accords, noting that some U.S. cities plan to honor the agreement despite Trump's decision. "American cities are signed on to the Paris Accords. We will do it ourselves," de Blasio said, according to a spokesman who was tweeting his speech at the “Hamburg Zeigt Haltung” rally. (TWEET-AT-LINK) De Blasio is in Germany for events surrounding the Group of 20 summit, where Trump and other world leaders have gathered to address topics including climate change. Every...

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...

Four in 10 Americans — or 39 percent — think the odds for human extinction because of climate change or global warming are 50 percent or more. But the majority of Americans, or 58 percent, think the odds of human extinction because of climate change is less than 50 percent, revealing that climate change is not a topic of universal agreement in the United States. This divide is revealed in a Yale University report titled “Climate Change in the American Mind.” “More than half of Americans (58%) believe climate change is mostly human caused,” the Yale report states. “That’s the...

Mann is the Penn State climatologist famous for inventing the "hockey stick" graph promoting the notion that planetary temperatures spiked in the 20th Century after a Golden Age of stasis...What Mann did was splice two separate data sets to create the illusion of spiking temperatures.

Donald Trump and Vladimir Putin are to meet for the first time today amid violent protest in Hamburg as the two leaders hold a full bilateral meeting, which will include a photocall and public comments. The timing of the meeting, which according to the White House’s schedule will start at 2.45pm, would mean the two leaders would be unlikely to take part in the working session on energy and climate change. Russia’s news agency Interfax said the meeting was at 3pm, UK time, which might allow them to attend the start.

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...

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.

Antarctica is set to lose a gigantic chunk of ice as scientists fear a 100-mile crack along the Larsen C ice shelf is about to give way. They have been observing the progress of the crack for months and the latest reports say there is only three miles of ice left connecting shelf together. When it breaks apart, the newly formed iceberg will measure around 2,500 square miles - roughly the size of the county of Devon - and contain three trillion tonnes of ice. It will be one of the largest icebergs ever recorded and will drift through the...

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.

Milloy request NEJM retraction: If PM2.5 kills, then it kills everywhere, in the same way, and all the time, and every study result should either be consistent with that hypothesis or be explained away as flawed or faulty... ...the NEJM Study as it, for example, lacks information on the cause of death for any individual in the Medicare population, relies entirely on guesstimated exposure data, and fails to consider confounding factors such as smoking, socioeconomic status and any of the other myriad potential competing risk factors for death.

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...

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...

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...
