The world's oceans are rising. Over the past century, they're up an average of about eight inches. But the seas are rising more in some places than others. And scientists are now finding that how much sea level rises in, say, New York City, has a lot to do with exactly where the ice is melting.
A warming climate is melting a lot of glaciers and ice sheets on land. That means more water rolling down into the oceans.
But the oceans are not like a bathtub. The water doesn't rise uniformly.
In a remote region of Antarctica known as Pine Island Bay, 2,500 miles from the tip of South America, two glaciers hold human civilization hostage.
Stretching across a frozen plain more than 150 miles long, these glaciers, named Pine Island and Thwaites, have marched steadily for millennia toward the Amundsen Sea, part of the vast Southern Ocean. Further inland, the glaciers widen into a two-mile-thick reserve of ice covering an area the size of Texas.
There’s no doubt this ice will melt as the world warms. The vital question is when.
AMYGOODMAN: This is Democracy Now!, democracynow.org. I’m Amy Goodman. We’re broadcasting live from the U.N. climate summit in Bonn, Germany. The International Energy Agency predicts U.S. oil production is expected to grow an unparalleled rate in the coming years, even as the majority of scientists worldwide are saying countries need to cut down on fossil fuel extraction, not accelerate it.
Three of the most intense hurricanes ever recorded just ripped through Puerto Rico and the southern US – within weeks of each other! Ash rained from the sky in Seattle and Portland for weeks. Record monsoons swept through Asia. Parts of Sierra Leone and Niger are underwater. San Francisco recorded its hottest day ever and Europe endured a triple-digit heat wave they called “Diablo.” The fucking devil is here man, and its name is climate change.
Think of the stickiest, record-hot summer you've ever experienced, whether you're 30 or 60 years old. In 10 years or less, that miserable summer will happen every second year across most of the US and Canada, the Mediterranean, and much of Asia, according to a study to be published in the open access journal Earth's Future.
Global warming might be far worse than we thought, according to a new study.
The research challenges the ways that researchers have worked out sea temperatures until now, meaning that they may be increasing quicker than previously suggested.
The methodology widely used to understand sea temperatures in the scientific community may be based on a mistake, the new study suggests, and so our understanding of climate change might be fundamentally flawed.
“Ophelia is breaking new ground for a major hurricane. Typically those waters much too cool for anything this strong. I really can’t believe I’m seeing a major just south of the Azores.” — National Hurricane Center scientist Eric Blake wrote on Twitter.
One of the crowning achievements of modern environmental science is the Keeling curve, the detailed time series of the concentration of atmospheric carbon dioxide (CO2) begun in 1958 that has enabled deep insights into the mechanisms of global climate change.
