One of Europe's leading scientists on Tuesday raised the possibility that the extreme heat wave now settled over at least 30 countries in the northern hemisphere could signal that man-made climate change is accelerating.
"The present heat wave across the northern hemisphere is worrying. There is the small probability that man-made climate change is proceeding much faster and stronger than expected," said Professor John Schellnhuber, former chief scientific adviser to the German government and now head of the UK's leading group of climate scientists at the Tyndall center.
Schellnhuber said "the parching heat experienced now" could be consistent "with a worst-case scenario [of global warming] that nobody wants to come true."

He warned that several months' research would be needed to analyze data from around the world before scientists could say why the heat waves are so intense this year.
"What we are seeing is absolutely unusual," Schellnhuber said. "We know that global warming is proceeding apace, but most of us were thinking that in 20 to 30 years time we would be seeing hot spells [like this]. But it's happening now. Clearly extreme weather events will increase."
Other climate scientists across Europe suggested the present heat wave was perhaps the most intense experienced and linked to global warming.
"We've not seen such an extended period of dry weather [in Europe] since records began," said Michael Knobelsdorf, a meteorologist at the German weather service. "What's remarkable is that these extremes of weather are happening at such short intervals, which suggests the climate is unbalanced. Last year in Germany, we were under water. Now we have one of the worst droughts in human memory."
Antonio Navarra, chief climatologist at Italy's National Geophysics Institute, said the Mediterranean region was 2?C to 3?C warmer than usual this summer.
Temperatures across parts of Europe have been a consistent 5?C warmer than average for several months, but the heat waves have extended across the northern hemisphere. Temperatures in some Indian states reached 45?C to 49?C, with more than 1,500 people dying as a direct result. There have been near-record temperatures in Canada and the US, Hawaii, China, parts of Russia and Alaska.
The intense heat in some places has given way to some of the most severe monsoon rains on record, a phenomenon also consistent with climate change models which predict extremes of weather. The heat waves are fuelling concern that climatologists may have underestimated the temperature changes expected with global warming.
According to the UN's intergovernmental panel on climate change (IPCC) -- the consensus of the world's leading 2,000 climatologists -- the expected increase is up to 5?C over the next century.
But a recent conference of leading atmospheric scientists in Berlin concluded that the IPCC's models may have underestimated the cooling effect of atmospheric soot, the airborne industrial waste of the past. The upper limit of global warming, they suggested, should range between 7?C and 10?C, which would severely affect food and water supplies, traumatize most economies and fundamentally change everyday life.
The UN's World Meteorological Organization (WMO) warned last month that extreme weather events would become more frequent. On Tuesday Ken Davidson, director of the WMO's climate program, said: "The world is seeing a change in general conditions and in extremes. We are trying to understand if it's getting more frequent."
Climate scientists at the British government's Hadley center last week said they had new evidence that the heat wave affecting Europe and North America could not be explained by natural causes, but must be partly due to pollution.
On Tuesday, Peter Stott, who led the research team, said: "Once we factor in the effects of human activity, we find we can explain the warming that is observed. Now we have gone a step further and shown that the same thing is happening on the scale of continents."
ANGER: A video shared online showed residents in a neighborhood confronting the national security minister, attempting to drag her toward floodwaters Argentina’s port city of Bahia Blanca has been “destroyed” after being pummeled by a year’s worth of rain in a matter of hours, killing 13 and driving hundreds from their homes, authorities said on Saturday. Two young girls — reportedly aged four and one — were missing after possibly being swept away by floodwaters in the wake of Friday’s storm. The deluge left hospital rooms underwater, turned neighborhoods into islands and cut electricity to swaths of the city. Argentine Minister of National Security Patricia Bullrich said Bahia Blanca was “destroyed.” The death toll rose to 13 on Saturday, up from 10 on Friday, authorities
Local officials from Russia’s ruling party have caused controversy by presenting mothers of soldiers killed in Ukraine with gifts of meat grinders, an appliance widely used to describe Russia’s brutal tactics on the front line. The United Russia party in the northern Murmansk region posted photographs on social media showing officials smiling as they visited bereaved mothers with gifts of flowers and boxed meat grinders for International Women’s Day on Saturday, which is widely celebrated in Russia. The post included a message thanking the “dear moms” for their “strength of spirit and the love you put into bringing up your sons.” It
DEBT BREAK: Friedrich Merz has vowed to do ‘whatever it takes’ to free up more money for defense and infrastructure at a time of growing geopolitical uncertainty Germany’s likely next leader Friedrich Merz was set yesterday to defend his unprecedented plans to massively ramp up defense and infrastructure spending in the Bundestag as lawmakers begin debating the proposals. Merz unveiled the plans last week, vowing his center-right Christian Democratic Union (CDU)/Christian Social Union (CSU) bloc and the center-left Social Democratic Party (SPD) — in talks to form a coalition after last month’s elections — would quickly push them through before the end of the current legislature. Fraying Europe-US ties under US President Donald Trump have fueled calls for Germany, long dependent on the US security umbrella, to quickly
In front of a secluded temple in southwestern China, Duan Ruru skillfully executes a series of chops and strikes, practicing kung fu techniques she has spent a decade mastering. Chinese martial arts have long been considered a male-dominated sphere, but a cohort of Generation Z women like Duan is challenging that assumption and generating publicity for their particular school of kung fu. “Since I was little, I’ve had a love for martial arts... I thought that girls learning martial arts was super swaggy,” Duan, 23, said. The ancient Emei school where she trains in the mountains of China’s Sichuan Province
