2019 atmospheric methane increase greatest in five years: preliminary data:
The National Oceanic and Atmospheric Administration (NOAA) found that the average level of methane in the atmosphere increased by 11.54 parts per billion (ppb) in 2019 over the level of methane in the atmosphere in 2018.
This is the largest increase since 2014, when the average level of atmospheric methane increased by 12.72 ppb.
Drew Shindell, an earth science professor at Duke University, called the 2019 increase “alarmingly high.”
Great Barrier Reef Is Bleaching Again. It’s Getting More Widespread.:
Temperatures in February, during the Southern Hemisphere summer, were far above that. It was the warmest month on record for water temperatures near the reef, with readings in some places peaking at more than 5 degrees Fahrenheit above average for the time of year.
Sea Levels Rising Faster than Expected | The Weather Channel:
More than double the average ice loss per year.
I know we have the global coronavirus pandemic to contend with; this is a reminder: climate change marches on, a tiny bit abated by the massive and immediate reduction in the world’s carbon footprint. That’s a little bit of good news.
The World’s Best Natural Defense Against Climate Change May Soon Make Things Worse:
Saunders and her colleagues are finding clues that over the past 12,000 years of Earth’s history, higher wind speeds and greater concentrations of carbon dioxide in the atmosphere have gone together. If this link between wind and CO₂ holds true today, it will lead to higher levels of the greenhouse gas in the atmosphere, which will speed up climate change, which could further intensify the westerlies.
There’s growing evidence that, at least in the winter months when the westerlies are at their most violent, some parts of the Southern Ocean are giving off more of the gas than was previously estimated. It has all the makings of a vicious cycle.
