Ozone across northern hemisphere increased over past 20 years


In a first-ever study using ozone data collected by commercial aircraft, researchers from the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder found that levels of the pollutant in the lowest part of Earth's atmosphere have increased across the Northern Hemisphere over the past 20 years. That's even as tighter controls on emissions of ozone precursors have lowered ground-level ozone in some places, including North America and Europe.

We should not forget the ozone higher up is helping to reduce dangerous rays from the sun.

Record melt: Greenland lost 586 billion tons of ice in 2019


Greenland lost a record amount of ice during an extra warm 2019, with the melt massive enough to cover California in more than four feet (1.25 meters) of water, a new study said.

After two years when summer ice melt had been minimal, last summer shattered all records with 586 billion tons (532 billion metric tons) of ice melting, according to satellite measurements reported in a study Thursday. That’s more than 140 trillion gallons (532 trillion liters) of water.

You know, I'm normally a 'glass half full' person but I don't see good things for the future. I believe we still have time to minimize a number of problems but we have leaders, around the world, who seem either incapable or don't care...

Emissions Could Add 15 Inches to 2100 Sea Level Rise, NASA-Led Study Finds


An international effort that brought together more than 60 ice, ocean and atmosphere scientists from three dozen international institutions has generated new estimates of how much of an impact Earth’s melting ice sheets could have on global sea levels by 2100. If greenhouse gas emissions continue apace, Greenland and Antarctica’s ice sheets could together contribute more than 15 inches (38 centimeters) of global sea level rise – and that’s beyond the amount that has already been set in motion by Earth’s warming climate.

Seas Are Rising. We Must Create Climate-Resilient Infrastructure — Now.


A new report on melting Antarctic ice sheets has dire implications for communities and infrastructure in the United States and across the world. Even if global warming is contained to 2 degrees Celsius above pre-industrial levels, the stated goal of the Paris Climate Accord that President Trump backed the U.S. out of in 2018, loss of Antarctic ice is still projected to cause sea levels to rise about 2.5 meters across the world. Ice loss is imminent even if temperatures fall after rising by 2 degrees Celsius because of an array of feedback loops that permanently destabilize the ice sheets, causing glaciers the size of Florida to fall into the ocean.
