Burning fossil fuels is causing the planet to heat up, causing weather patterns to change, sea levels to rise and diseases to spread.Temperatures vary from place to place. Still, across the planet there has been a trend of steadily increasing warmth.Global temperatures naturally bounce around from day to day, season to season and year to year. But average temperatures have risen exceptionally fast since the late 1800s. One big reason: Humans have been spewing pollutants into the air that hold in the sun’s warming rays.
One of Antarctica’s largest ice shelves is nearing its breaking point!. Satellite images in 2014 revealed that a crack in Larsen C rapidly extended across the ice shelf. If the crack reaches the ice shelf’s edge, it could snap off a Delaware-sized area of ice, researchers reported roughly 18 months ago. Such a loss would reduce “Larsen C’s” size by about 10 percent. That’s enough to shrink the shelf to its smallest size in recorded history.an Antarctic research group, reported the crack's dramatic growth on January 5. This separating ice is now only about 20 kilometers from “Larsen C’s” edge.
The ocean surrounds Florida on three sides. That water is warm as a bathtub. This seawater heats the atmosphere all around it.Florida simply doesn’t get that cold. It normally doesn’t, anyway. That’s why any snow in Florida is rare. December’s snow made it all the way down to the Mexican border. It created a beautiful view that many people that live there have never seen before. After all, you don’t usually see snow falling in the branches of palm trees. By that time this winter picked up more of the frozen white stuff than had so far hit the traditionally snowy cities of Boston, Chicago, Minneapolis, Detroit and Denver.
Scientists these days are worried about sea level. As Earth warms, the surface of the ocean is creeping upward. This creep is happening partly because saltwater expands a tiny bit as it warms. “Warmer water literally is taller,” says science news for kids. Sea level also is rising because warm temperatures that are making glaciers melt in Antarctica, Greenland and other usually cold places to melt more quickly. Glaciers are rivers of ice, and their melting adds freshwater to the ocean. Antarctica and Greenland are together “losing about 350 cubic kilometers of ice per year — enough meltwater to fill up 80,000 Yankee baseball stadiums,” states science news for kids.
