Meteorologists predict a historic El Nino event that could exacerbate global weather extremes, affecting agriculture, economies, and climate patterns worldwide.

WASHINGTON: The weather phenomenon El Nino has arrived, the US National Oceanic and Atmospheric Administration said Thursday (Jun 11), and scientists expect it will intensify into the end of the year,

A weather pattern named for the Greek letter omega is guiding US weather, forecasters said. The pattern is expected to continue into June.

Earth is divided into two halves: the Northern and Southern Hemispheres. Both reflect equal amounts of sunlight (albedo) even though they have different landmasses and weather patterns, especially cloud distribution.

Past Center surveys have found that Americans with higher levels of formal education are more likely to say human activity is a big cause of climate change. This pattern is driven by Democrats. In contrast, Republicans of all education levels are unlikely to say climate change is mostly the result of human activity.

As temperatures neared their midday peak, Hu Xiaosong was doing his regular patrol, at an altitude of more than 5,500 feet, to protect a 1,000-year-old pine tree that he says is like family to him.

Two specific weather patterns have been identified as capable of increasing the risk of headaches, thanks to physicians at the University of Cincinnati College of Medicine, along with researchers at the Icahn School of Medicine at Mount Sinai,

Researchers have uncovered a key mechanism behind Japan's extreme winter weather, revealing how distant climate patterns interact to intensify cold waves and heavy snowfall.

The global weather pattern threatens to worsen floods and heat waves already intensifying due to climate change. But it may also mean fewer hurricanes.
