Climate records back to Viking times show the 20th century was unexceptional for rainfall and droughts despite assumptions that global warming would trigger more wet and dry extremes, a study showed on Wednesday. Stretching back 1,200 years, written accounts of climate indicated that variations in the extremes in the 20th century were less than in some past centuries. "Several other centuries show stronger and more widespread extremes," lead author Fredrik Ljungqvist of Stockholm University told Reuters. "We can't say it's more extreme now." Ljungqvist said many existing scientific models of climate change over-estimated assumptions that rising temperatures would make dry...

What is your position on the climate-change debate? What would it take to change your mind? If the answer is It would take a ton of evidence to change my mind, because my understanding is that the science is settled, and we need to get going on this important issue, that’s what I thought, too. This is my story. More than thirty years ago, I became vegan because I believed it was healthier (it’s not), and I’ve stayed vegan because I believe it’s better for the environment (it is). I haven’t owned a car in ten years. I love animals;...

When future generations look back on the global-warming scare of the past 30 years, nothing will shock them more than the extent to which the official temperature records – on which the entire panic ultimately rested – were systematically “adjusted” to show the Earth as having warmed much more than the actual data justified. Two weeks ago, under the headline “How we are being tricked by flawed data on global warming”, I wrote about Paul Homewood, who, on his Notalotofpeopleknowthat blog, had checked the published temperature graphs for three weather stations in Paraguay against the temperatures that had originally been...

Most of the people of the world have concluded that the decades of warnings about “global warming” and its successor, “climate change”, is just idiotic nonsense. Few believe that humans ever had or ever will have any role in what the weather will be tomorrow or a thousand years from now. They are right. One of the most distinguishing factors about the Anthropogenic Global Warming theory has been the way its advocates have always predicted major changes decades into the future. When the future arrived, as it has since the first doomsday predictions were made in the late 1980s, they...

Scientists have noticed that while greenhouse gases have continued to mount in the first part of the 21st century, global average surface air temperatures have stopped rising along with them, said Nasa. Some studies have suggested that heat is being absorbed temporarily by the deep seas, and that this so-called global warming hiatus is a temporary trend. But the latest data from satellite and direct ocean temperature measurements from 2005 to 2013 "found the ocean abyss below 1,995 metres has not warmed measurably", Nasa said in a statement.

Scientists are to challenge the climate-change sceptics by vastly improving the speed with which they can prove links between a heatwave or other extreme weather event and man-made changes to the atmosphere.

As the Obama administration undertakes a highly public, multilateral campaign to degrade and destroy the militant jihadists known as ISIS, ISIL and the Islamic State, many in the West remain unaware that climate played a significant role in the rise of Syria's extremists. The Huffington Post... Global Warming has now created ISIS.

On Monday, Dr. David Agus injected the media's regular hype about climate change into CBS This Morning's coverage of the outbreak of Enterovirus D68 in the U.S. and the Ebola crisis in Africa. The morning show brought on Dr. Agus to discuss the polio-like virus that has afflicted children across the country. Near the end of the segment, anchor Charlie Rose wondered, "So we have Ebola virus in Africa, and we now have this virus [Enterovirus D68]. What's going on?" The CBS medical contributor admitted that science didn't have any answers at this point, but that didn't stop him from...

Your SUV is apparently responsible for all those beheadings in the Middle East. That’s right: ISIS is nothing more than a product of global warming, according to some non-scientist from John Jay College in New York. I know I was surprised to learn that 1.4 degrees of warming (over the last century) was enough to push the cradle of civilization into mass chaos. (Because, as we all know, it has always been such a peaceful corner of the world up until recently.)According to Charles Strozier, Professor of History and the founding Director of the John Jay College Center on Terrorism, your...

Tuesday's climate summit at the U.N. may well mark a turning point in the long-running talks as the reality sinks in that they are heading nowhere. For sure, the rhetoric is unchanged. Recently appointed U.N. peace messenger Leonardo DiCaprio is the show’s newest star, telling the meeting that it was "humankind’s greatest challenge." But the older acts sounded stale. Former Vice President Al Gore demonstrated his green credentials when he said that political will was "a renewable resource," recycling a line he’d first used at the 2007 Bali climate conference. For small countries, the U.N. climate change talks provide an...

ABSTRACT A review of the research literature concerning the environmental consequences of increased levels of atmospheric carbon dioxide leads to the conclusion that increases during the 20th and early 21st centuries have produced no deleterious effects upon Earth's weather and climate. Increased carbon dioxide has, however, markedly increased plant growth. Predictions of harmful climatic effects due to future increases in hydrocarbon use and minor greenhouse gases like CO2 do not conform to current experimental knowledge. The environmental effects of rapid expansion of the nuclear and hydrocarbon energy industries are discussed. CONCLUSIONS There are no experimental data to support the hypothesis...

Secretary of State John Kerry, the world's top diplomat, is warning that global warming climate change poses as much of a threat to the world as ISIS. More from The Hill: Secretary of State John Kerry said the threats posed by climate change should be addressed with as much "immediacy" as confronting the Islamic State in Iraq and Syria (ISIS), and the Ebola outbreak. During a meeting with foreign ministers on Sunday, Kerry said global warming is creating "climate refugees." "We see people fighting over water in some places. There are huge challenges to food security and challenges to the...

Eric Worrall writes: The imminent climate summit in New York is rapidly turning into an utter embarrassment for President Obama and UN Secretary General Bank Ki-Moon, in addition to becoming a bit of a punishment round for national deputy leaders.Aussie PM Tony Abbott today defended his decision not to hop on an earlier flight to America, so he could attend the UN climate conference in New York, because he has more important matters to attend to, such as running the country.http://www.heraldsun.com.au/news/national/tony-abbott-defends-skipping-un-climate-change-summit-in-new-york/story-fni0xqrb-1227060005413Chinese President Xi Jinping and Indian Prime Minister Narendra Modi have also indicated they likely won’t attend the summit.http://thediplomat.com/2014/09/top-leaders-from-china-india-to-skip-un-climate-change-summit/Canadian Prime...

It appears that reality is not cooperating with the myth that man-made CO2 is causing global warming. Recent satellite images show that both the Arctic and the Antarctic sea ice have dramatically increased in size and thickness. Despite Al Gore’s 2007 apocalyptic predictions that in just 7 more years the Arctic ice cap will be “completely gone,” it has instead dramatically increased by 43% in size since 2012. The North Pole ice cap grew by 1.715 million square kilometers, an area the size of Alaska, in the last two years. In solidarity, the South Pole ice cap has also reached...

All right, so we're slightly premature. By one measure - according to Bishop Hill - we're still a month away before "no global warming" achieves its coming of age. But by other measurements, as Matt Ridley notes in the Wall Street Journal, we're already as much as 19 or even 26 years into "no global warming" "depending on whether you choose the surface temperature record or one of two satellite records of the lower atmosphere."

The hiatus in the rise in global temperatures could last for another 10 years, according to new research. Scientists have struggled to explain the so-called pause that began in 1999, despite ever increasing levels of CO2 in the atmosphere. The latest theory says that a naturally occurring 30-year cycle in the Atlantic Ocean is behind the slowdown. The researchers says this slow-moving current could continue to divert heat into the deep seas for another decade. However, they caution that global temperatures are likely to increase rapidly when the cycle flips to a warmer phase. Continue reading the main story “...

A globally-renowned climate scientist has been forced to step down from a think-tank after he was subjected to 'Mc-Carthy'-style pressure from scientists around the world. Professor Lennart Bengtsson, 79, a leading academic from the University of Reading, left the high-profile Global Warming Policy Foundation as a result of the threats, which he described as 'virtually unbearable'. The group was set up by former Tory Chancellor Lord Lawson and are sceptical about radical policy changes aimed at combating global warming. The Swedish climatologist, who has published more than 200 papers, said he received hundreds of emails from colleagues criticising his decision...

A recent headline in the New York Times says “Scientists Warn of Rising Oceans from Polar Melt.” Other newspapers propagated the story with titles like “Ice sheet collapse ‘unstoppable,’ scientists warn” and “Huge Antarctic ice sheet collapsing.” The story refers to two recent publications that conclude that “warm water upwelling from the [Antarctic] ocean depths has most likely triggered an inherent instability” that will lead to the envisaged collapse. There are some problems with such predictions: The facts show otherwise.

When a team of researchers from the University of Delaware traveled to Africa two years ago to search for exemplary chickens, they weren't looking for plump thighs or delicious eggs. They were seeking out birds that could survive a hotter planet. The researchers were in the vanguard of food scientists, backed by millions of dollars from the federal government, racing to develop new breeds of farm animals that can stand up to the hazards of global warming.

Most of us pay some attention to the weather forecast. If it says it will rain in your area tomorrow, it probably will. But if it says the same for a month, let alone a year, later, it is much less likely to be right. There are too many imponderables. The theory of global warming is a gigantic weather forecast for a century or more. However interesting the scientific inquiries involved, therefore, it can have almost no value as a prediction. Yet it is as a prediction that global warming (or, as we are now ordered to call it in...
