World on ‘thin ice’ as UN climate report gives stark warning
Humanity still has a chance, close to the last, to prevent the worst of climate change’s future harms, a top United Nations panel of scientists said Monday.
But doing so requires quickly slashing nearly two-thirds of carbon pollution by 2035, the Intergovernmental Panel on Climate Change said. The United Nations chief said it more bluntly, calling for an end to new fossil fuel exploration and for rich countries to quit coal, oil and gas by 2040.
“Humanity is on thin ice — and that ice is melting fast,” United Nations Secretary-General Antonio Guterres said. “Our world needs climate action on all fronts — everything, everywhere, all at once.”
Stepping up his pleas for action on fossil fuels, Guterres called for rich countries to accelerate their target for achieving net zero emissions to as early as 2040, and developing nations to aim for 2050 — about a decade earlier than most current targets. He also called for them to stop using coal by 2030 and 2040, respectively, and ensure carbon-free electricity generation in the developed world by 2035, meaning no gas-fired power plants either.
That date is key because nations soon have to come up with goals for pollution reduction by 2035, according to the Paris climate agreement. After contentious debate, the U.N. science report approved Sunday concluded that to stay under the warming limit set in Paris the world needs to cut 60% of its greenhouse gas emissions by 2035, compared with 2019, adding a new target not previously mentioned in six previous reports issued since 2018.
“The choices and actions implemented in this decade will have impacts for thousands of years,” the report said, calling climate change “a threat to human well-being and planetary health.”
“We are not on the right track but it’s not too late,” said report co-author and water scientist Aditi Mukherji. “Our intention is really a message of hope, and not that of doomsday.’’
With the world only a few tenths of a degree away from the globally accepted goal of limiting warming to 1.5 degrees Celsius since pre-industrial times, scientists stressed a sense of urgency. The goal was adopted as part of the 2015 Paris climate agreement and the world has already warmed 1.1 degrees Celsius.
This is likely the last warning the Nobel Peace Prize-winning collection of scientists will be able to make about the 1.5 mark because their next set of reports may well come after Earth has either passed the mark or is locked into exceeding it soon, several scientists, including report authors, told The Associated Press.
After 1.5 degrees “the risks are starting to pile on,” said report co-author Francis X. Johnson, a climate, land and policy scientist at the Stockholm Environment Institute. The report mentions “tipping points” around that temperature of species extinction, including coral reefs, irreversible melting of ice sheets and sea level rise of several meters.
“1.5 is a critical critical limit, particularly for small islands and mountain (communities) which depend on glaciers,” said Mukherji.
“The window is closing if emissions are not reduced as quickly as possible,” Johnson said in an interview. “Scientists are rather alarmed.”
Many scientists, including at least three co-authors, said hitting 1.5 degrees is inevitable.
“We are pretty much locked into 1.5,” said report co-author Malte Meinshausen, a climate scientist at the University of Melbourne in Australia. “There’s very little way we will be able to avoid crossing 1.5 C sometime in the 2030s ” but the big issue is whether the temperature keeps rising from there or stabilizes.
Guterres insisted “the 1.5-degree limit is achievable.” Science panel chief Hoesung Lee said so far the world is far off course.
If current consumption and production patterns continue, Lee said, “the global average 1.5 degrees temperature increase will be seen sometime in this decade.”
Scientists emphasize that the world or humanity won’t end suddenly if Earth passes the 1.5 degree mark. Mukherji said “it’s not as if it’s a cliff that we all fall off.” But an earlier IPCC report detailed how the harms — including even nastier extreme weather — are much worse beyond 1.5 degrees of warming.
“It is certainly prudent to be planning for a future that’s warmer than 1.5 degrees,” said IPCC report review editor Steven Rose, an economist at the Electric Power Research Institute in the United States.
If the world continues to use all the fossil fuel-powered infrastructure either existing now or proposed, Earth will warm at least 2 degrees Celsius since pre-industrial times, the report said.
Because the report is based on data from a few years ago, the calculations about fossil fuel projects already in the pipeline do not include the increase in coal and natural gas use after Russia’s invasion of Ukraine. It comes a week after the Biden Administration in the United States approved the huge Willow oil-drilling project in Alaska, which could produce up to 180,000 barrels of oil a day.

State of Emergency declared in Florida ahead of hurricane Milton
Weather experts say impacts ranging from a devastating storm surge to major flooding from rain, damaging wind gusts, pounding surf and tornadoes are expected in Florida
A state of emergency has been declared in Florida ahead of Milton, which is forecast to plow into the western peninsula on Wednesday as a major hurricane
This comes just days after the devastating Hurricane Helene caused extensive damage to the region earlier this month.
Milton, another significant tropical threat to the US, is lurking in the Gulf of Mexico, AccuWeather experts have reported.
These weather experts say impacts ranging from a devastating storm surge to major flooding from rain, damaging wind gusts, pounding surf and tornadoes are expected in Florida.
Because of the risk, Florida Governor Ron DeSantis has declared a state of emergency and is urging that preparations to protect life and property should begin immediately.
“This is an unusual and extremely concerning forecast track for a hurricane approaching the Tampa Bay area,” warned AccuWeather Chief Meteorologist Jonathan Porter.
“Milton could rapidly intensify into a major hurricane with extreme impacts. This hurricane could create a life-threatening storm surge,” he said.
AccuWeather meteorologists reported Monday that before Milton moves ashore in Florida, it will have ample time to rapidly strengthen over the very warm waters of the Gulf of Mexico. T
"The ocean heat content is at the highest level on record for this time of year in the Gulf, despite the recent passage of Helene," added AccuWeather Lead Hurricane Forecaster Alex DaSilva.
"The deep, warm waters can act like rocket fuel for Milton, allowing for rapid intensification."
The threat posed by heavy rain will precede Milton's arrival by several days. Heavy rain was already falling over the Florida peninsula this weekend, and will continue through the early part of the week, well ahead of impacts from wind and storm surge.
Milton is the thirteenth named storm of the 2024 Atlantic hurricane season. Hurricanes Kirk and Leslie were also churning across the open Atlantic as of late this weekend, though neither pose an immediate, direct threat to land.

Rescuers search for missing people in Nepal following flooding and landslides that killed 224
The death toll climbed to 224 and the injured to 158 while rescue efforts were still underway on Wednesday to look for 24 others
Rescuers in Nepal searched Tuesday for two dozen people still missing and tried to recover the bodies of those killed in weekend flooding and landslides that left more than 200 dead.
The disaster came just ahead of the country’s biggest festival Dasain, which begins on Thursday, and roads were busier than usual as people returned home to celebrate with loved ones. The damage to roads is likely to hamper travel plans, Associated Press reported.
The deaths climbed to 224 and the injured to 158 while rescue efforts were underway to look for 24 others, said the government’s chief secretary Eak Narayan Aryal on Tuesday.
Prime Minister Khadga Prasad Oli’s administration has been heavily criticized for its slow response to the crisis, particularly after a landslide hit several vehicles stranded for hours just 16 kilometers from the capital, Kathmandu, killing about three dozen people.
Oli told reporters the government would continue to look for those missing and help the thousands impacted.
As the weather improved, workers started clearing the highways by the mountains after being blocked by landslides. Sections of several other highways next to raging rivers were washed away and repairing them is expected to require time and effort.
Of the 37 highways damaged, only nine have so far reopened for traffic.
The flooding was caused by heavy rain which arrived at the end of Nepal’s monsoon season that usually begins in June and ends by mid-September. Experts have attributed Nepal’s changing rain pattern to climate change.

US southeast faces daunting task cleaning up from Helene; death toll rises
At least 3.5 million customers remained without power across five states, with authorities warning it could be several days before services were fully restored.
Authorities across a wide swath of the southeastern United States faced the daunting task on Saturday of cleaning up from Hurricane Helene, one of the most powerful to hit the country, as the death toll continued to rise.
At least 43 deaths were reported by late on Friday, and officials feared still more bodies would be discovered across several states, Reuters reported.
Helene, downgraded late on Friday to a post-tropical cyclone, continued to produce heavy rains across several states, sparking life-threatening flooding that threatened to create dam failures that could inundate entire towns.
In Florida's Pinellas County near Tampa, Sheriff Bob Gualtieri said he had never seen destruction like that which Helene wrought. "I would just describe it, having spent the last few hours out there, as a war zone," Gualtieri told a press conference.
At least 3.5 million customers remained without power across five states, with authorities warning it could be several days before services were fully restored.
Scientists say climate change contributes to fueling stronger, more destructive hurricanes.
Before moving north through Georgia and into Tennessee and the Carolinas, Helene hit Florida's Big Bend region as a powerful Category 4 hurricane on Thursday night, packing 140 mph (225 kph) winds. It left behind a chaotic landscape of overturned boats in harbors, felled trees, submerged cars and flooded streets.
Police and firefighters carried out thousands of water rescues throughout the affected states on Friday.
More than 50 people were rescued from the roof of a hospital in Unicoi County, Tennessee, about 120 miles (200 km) northeast of Knoxville, state officials said, after floodwaters swamped the rural community.
Rising waters from the Nolichucky River prevented ambulances and emergency vehicles from evacuating patients and others there, the Unicoi County Emergency Management Agency said on social media. Emergency crews in boats and helicopters were conducting rescues.
Elsewhere in Tennessee, Rob Mathis, the mayor of Cocke County, ordered the evacuation of downtown Newport because of a potential failure at the nearby Walters dam.
In western North Carolina, Rutherford County emergency officials warned residents near the Lake Lure Dam that it might fail, although they said late on Friday that failure did not appear imminent.
In nearby Buncombe County, landslides forced interstates 40 and 26 to close, the county said on X.
