In West Antarctica, the interior of the ice sheet sits atop bedrock that lies well below sea level. As the Southern Ocean warms, scientists are concerned the ice sheet will continue to retreat, potentially raising sea level by several meters.
Weather and Climate
A team of scientists’ climate projections for 2500 show an Earth that is alien to humans. Heat stress may reach fatal levels for humans in tropical regions which are currently highly populated. Such areas might become uninhabitable. Even under high-mitigation scenarios, we found that sea level keeps rising due to expanding and mixing water in warming oceans.
Tropical Storm Mindy formed late this afternoon over the northern Gulf of Mexico and veered east in a rapid trek expected to take it from Florida’s Big Bend through the northeast portion of the state over the next 24 hours. Impacts in Flagler County are expected to be limited to rain and some wind, but the county’s emergency chief cautions about rapidly changing patterns.
Flagler County urges residents to do as it has and recognize September as National Preparedness Month, which is done to raise awareness about the importance of preparing for disasters and emergencies that could happen at any time. This year’s theme is “Prepare to Protect.”
Underground lines are susceptible to damage from water incursion driven by storm surges or flooding. So, choosing the location of power lines means choosing which threat is more manageable. And the public ultimately pays for maintaining the power grid, either via their electric bills or through taxes.
The heat will get much worse, warns the Union of Concerned Scientists in a new climate-focused report titled “Too Hot To Work.” The report says 2 million outdoor workers in Florida, about one-fourth of the workforce, could lose more than $8 billion in annual earnings over the next four decades due to inability to work in increasingly dangerous heat.
Evidence is mounting that, as the climate warms, the amount of precipitation from heavy rainstorms is increasing, especially in the central and eastern U.S. As the climate changes, risks of major flooding events will only increase further.
As Hurricane Ida headed into the Gulf of Mexico, a team of scientists was closely watching a giant, slowly swirling pool of warm water directly ahead in its path. That warm pool, an eddy, was a warning sign.
For now, Fred–the name, short for Frederick, means “peaceful ruler”–is some 350 miles southeast of Puerto Rico, with maximum sustained winds of 35 mph. The National Hurricane Center gives it a 90 percent chance of becoming a tropical storm “later today or tonight,” but its further track is very uncertain.
Humans are unequivocally warming the planet, and that’s triggering rapid changes in the atmosphere, oceans and polar regions, and increasing extreme weather around the world, the Intergovernmental Panel on Climate Change warns in a new report issued today.
