The US Has Destroyed A Critical Sea Ice-Measuring Satellite (scientificamerican.com)
"A key polar satellite used to measure the Arctic ice cap failed a few days ago, leaving the U.S. with only three others, and those have lived well beyond their shelf lives," writes long-time Slashdot reader edibobb. The Guardian reports that all three of the remaining satellites "are all beginning to drift out of their orbits over the poles" and will no longer be operational by 2023. This could put an end to nearly 40 years of uninterrupted data on polar ice, notes the original submission, adding "It seems like there would be a backup satellite, right?
"In fact, there was a backup satellite ready to go." The $58 million satellite was dismantled in 2016 when the Republican-controlled Congress cut its funding. (The Guardian reports that many scientists "say this decision was made for purely ideological reasons.") Now Nature reports: The U.S. military is developing another set of weather satellites...but the one carrying a microwave sensor will not launch before 2022. That means that when the current three aging satellites die, the United States will be without a reliable, long-term source of sea-ice data... For now, the the U.S. National Snow and Ice Data Center is preparing for those scenarios by incorporating data from Japan's AMSR2 microwave sensor into its sea-ice record. Another, more politically fraught option is to pull in data from the China Meteorological Administration's Fengyun satellite series... Since 2011 Congress has banned NASA scientists from working with Chinese scientists -- but not necessarily from using Chinese data. One final possibility is finding a way to launch the passive-microwave sensor that scientists at the U.S. Naval Research Laboratory salvaged from the dismantled DMSP satellite. The sensor currently sits at the Aerospace Corporation in El Segundo, California, where researchers are trying to find a way to get it into orbit.

This. These liberal utopian thinkers want the government to do everything for them. I'm sure you'll be fine without data for some months.
Really, I thought it was tax breaks for those earning $450,000 per year, a.k.a. the "middle class".
Only crack the nuts that crack. You don't put the ones that don't crack in the sack.
You do realize that this latest mass shooting was stopped by a citizen with a gun, right? Had that citizen not had a gun, probably a lot more people would have died. If some of the people in that church had been carrying, it possibly would have ended much sooner. It's not the gun, it's the person using (or misusing) a gun that can be the problem.
