The conservation authority listed the water level at 219.4 metres Friday, which is 31 centimetres higher than normal for this time of year. Higher than average water levels in Lake Simcoe are causing worry amongst farmers in Ontario's 'salad bowl' region, which is a major vegetable producer in the province.

"The responders weren't just FEMA, it was people taking up direct collections for food, for clothing; it was a community response."

High pressure will remain broadly in charge of the UK's weather for the remainder of this week and into the weekend. Most places will remain dry with a fair amount of sunshine too.

The mudslide in Petropolis in February 2022 killed 233 people, and displaced many more. Over the past decade, climate-related disasters have displaced 250 million people globally, equivalent to 70,000 people forced from their homes every day.

The UK Health Security Agency reported around 1,504 heat-associated deaths in England during summer 2025, roughly half the predicted 3,039, despite the season being the warmest on record.

The study highlights how rapid Arctic warming increases the frequency of extreme weather events, particularly concurrent heatwaves across Europe and eastern Asia.

Researchers have known since at least 2008 that wildfires can create chromium-6, but a new study, published in the journal Environmental Science and Technology in November, is the first to report details such as how long it might persist in groundwater.

During this heat wave, "not only are daily temperature records likely to be broken across the region, but even the high temperature records for any day in the entire month of March," the National Weather Service said in a Tuesday morning forecast.

"So whenever people think about hot weather, they always talk about the temperature," he says. "There's two issues with that. First of all, most people don't realise that the temperature is measured in the shade. So if you're in direct solar radiation, the amount of heat stress you're exposed to is much greater as it will stress your body out a lot more."

Because the past three years have shattered temperature records, researchers have been exploring whether global warming is accelerating, and if so, why. Many scientists agree that the rate at which it is increasing has picked up. This is mainly because of a reduction in air pollution following the introduction of fuel regulations for international shipping (which has resulted in fewer pollutant particles that reflect sunlight into space and seed insulating clouds).

An extraordinarily warm and mostly sunny January has left the snowpack across California's Sierra Nevada far smaller than usual - 59% of average for this time of year, state water officials announced Friday as they held the season's second snow survey. "We are now about halfway through the typically wettest part of the year," said Andy Reising, manager of snow surveys for the California Department of Water Resources.

While cold-stunned iguanas fall from trees in Florida and videos circulate of frozen "exploding" trees in the Northeast, Southern California is working up a sweat. A midwinter heat wave has descended on much of the state and is expected to spike temperatures as much as 20 degrees above normal in the coming week. The summer-like heat is thanks to a ridge of high pressure lingering high in the atmosphere that extends through the San Francisco Bay Area and into the Pacific Northwest.
