The Melting of Large Icebergs is a Key Stage in the Evolution of Ice Ages. Climate migration — Quartz Weekly Obsession. The climate fix you’ve been waiting for: Rock dust? Scientists have been trying to figure out how to make use of one of nature’s tricks for removing carbon dioxide from the atmosphere with rock and rain.
As rain washes away tiny particles of rock, newly exposed minerals bind with carbon, transforming carbon dioxide into new chemicals. It’s a simple combination of basic chemistry and erosion. We can speed the process up by speeding up erosion, crushing tons and tons of rock and spreading it across the earth’s surface, if we had the money to do it and a vast area where inhabitants don’t mind trucks covering everything with a layer of rock dust once a year. Farms are the most likely candidate for such a massive undertaking, because farmers already do some incidental advanced weathering as a byproduct of “liming”, where they apply crushed limestone to fields when their soils become too acidic. Will Florida be lost forever to the climate crisis? Few places on the planet are more at risk from the climate crisis than south Florida, where more than 8 million residents are affected by the convergence of almost every modern environmental challenge – from rising seas to contaminated drinking water, more frequent and powerful hurricanes, coastal erosion, flooding and vanishing wildlife and habitat.
If scientists are right, the lower third of the state will be underwater by the end of the century. Yet despite this grim outlook, scientists, politicians, environment groups and others are tackling the challenges head on. Below are some of the biggest threats posed by the climate crisis to south Florida today, along with solutions under consideration. Some of these solutions will have a lasting impact on the fight. Others, in many cases, are only delaying the inevitable. Study reveals one climate strategy could save the world $616 trillion. Climate change isn't all about cost.
It can be about gain, too. A new study reveals following one climate change-mitigation strategy could save the world as much as $616 trillion. In the study, researchers simulate a number of possible scenarios to determine the ideal way the world can combat the worst effects of climate change — and what might happen if we don't do anything to curb its insidious effects.
It comes down to countries cooperating at a global scale. New decade starts with climate change bills, regulatory rollbacks and investor pressure - Axios. Where it stands: It was easy to miss those developments with all of the alarming headlines of the last 13 days.
America flirted with a Mideast war, the oil market surprisingly shrugged it off, a plane was shot from the sky, the impeachment saga feels like old news but is still very much a thing, and Australia is burning. Cue a modern-day rendition of 1989’s We Didn’t Start The Fire. NASA releases 50-year timelapse video of earth’s changing glaciers. NASA has released a new time-lapse video capturing the earth’s glaciers and ice sheets as seen from space, providing scientists with new insights into how the planet’s frozen regions are changing. the video, which takes images from the landsat mission dating back to 1972 and continuing though 2019, shows the speed-up of glacial retreat starting in 2000, as well as meltwater ponds spreading to higher elevations, potentially speeding up ice flow, and revealing lakes hidden beneath the winter snow.
‘we now have this long, detailed record that allows us to look at what’s happened in alaska,’ comments mark fahnestock of the university of alaska fairbanks, who has stitched together six-second time-lapses of every glacier in alaska and the yukon. ‘when you play these movies, you get a sense of how dynamic these systems are and how unsteady the ice flows.’ in the past 50 years, glaciers are birthing more ice into the ocean than ever before through meltwater lakes. Juliana neira I designboom. Climate Change: Florida Will See Disastrous King Tides, Wastewater from Septic Tanks. While the nation's attention is directed at the ongoing burlesque of democratic government in Washington, D.C. those clever Chinese climate hoaxsters are hard at work giving places like Florida a sneak preview of coming attractions.
From the Weather Channel: Higher sea levels threaten the systems that carry wastewater away from more than one in five households in the United States, according to the U.S. Environmental Protection Agency. These homes use septic tanks that rely on dry soil to work properly. America's great climate exodus is starting in the Florida Keys. Lori Rittel is stuck in her Florida Keys home, living in the wreckage left by Hurricane Irma two years ago, unable to rebuild or repair.
Now her best hope for escape is to sell the little white bungalow to the government to knock down. Her bedroom is still a no-go zone so she sleeps in the living room with her cat and three dogs. She just installed a sink in the bathroom, which is missing a wall, so she can wash her dishes inside the house now. Weather reports make her nervous. “I just want to sell this piece of junk and get the hell out,” she said.
‘Mystery’ volcano that cooled the ancient world traced to El Salvador. The sixth century was a rough time to be alive: Lower-than-average temperatures in the Northern Hemisphere triggered crop failure, famine, and maybe even the onset of bubonic plague.
The ultimate culprit, scientists say, were two back-to-back volcanic eruptions—one in 536 C.E. and another around 540 C.E. The first likely happened in Iceland or North America. But the location of the second one has remained a mystery—until now. Researchers studying ancient deposits from El Salvador’s Ilopango volcano knew that a massive eruption had taken place there sometime between the third and sixth centuries. That event, dubbed Tierra Blanca Joven (TBJ), or “white young earth,” sent a volcanic plume towering nearly 50 kilometers into the atmosphere. These Are the US Military Bases Most Threatened by Climate Change. The belated lists arrived just ahead of a GAO report that says the Pentagon is failing to use climate projections in planning.
After a five-month delay, U.S. lawmakers can finally see which military bases are most threatened by climate change — information that arrived just ahead of a Congressional finding that the Defense Department has little idea how to prepare for these threats. Each service evaluated its infrastructure’s vulnerability to increased flooding, drought, and wildfires; thawing permafrost; rising rivers and coasts; and other effects of climate change. The four services flagged a total of 46 bases as particularly threatened. Changes in ocean 'conveyor belt' foretold abrupt climate changes by four centuries. Hattip geofish The oceans are a huge factor in global climate change.

Huge ancient ice wall across the Bering Strait may have triggered Ice Age. First geoengineering experiment to dim the sun on track for 2019. Harvard scientists will attempt to replicate the climate-cooling effect of volcanic eruptions with a world-first solar geoengineering experiment set for early 2019. The Stratospheric Controlled Perturbation Experiment (SCoPEx) will inject calcium carbonate particles high above the earth in an attempt to reflect some of the sun's rays back into space.
It will likely mark the first time the controversial concept of dimming the sun — more scientifically known as stratospheric aerosol injection (SAI) — will be tested in the real world. Existing understanding of SAI comes from computer modelling and also from observing the natural effects of volcanoes, which create a haze of sulphate particles that effectively cool the planet. The 1991 Mount Pinatubo eruption in the Philippines, for instance, caused the average global temperature to drop by about 0.6 degrees Celsius in the following 15 months.
Harvard team plans to launch experiment in early 2019. Global Warming Is Setting Fire to American Leadership. U.S. President Donald Trump has said, “I don’t believe” climate change is real.

In the early years of the 20th century, several teams of explorers were racing to reach a new frontier: the South Pole. During what's known as the Heroic Age of Antarctic Exploration, many explorers perished and the expeditions were fraught with failure, but their efforts were not in vain. Now, over a century later, their logbooks and journals have helped piece together a new discovery: Antarctic sea ice coverage may not be on a steady downward trend, but fluctuating over cycles lasting decades.
