#WashingtonPost 📆 February 12, 2022 A #SolarStorm caused #Earth’s #atmosphere to inflate, or puff out.

Think of Earth’s atmosphere like a bicycle tire. When the first solar storm hit, its #magnetic 🧲 field drove currents that caused Earth’s upper atmosphere and particles to move in one direction. When the second surprise solar storm hit, it was oriented in such a way as to cause the motion of Earth’s upper atmosphere to reverse direction. The friction and energy of the two opposing forces released heat in quantities more than models had anticipated https://www.washingtonpost.com/weather/2022/02/12/spacex-starlink-explainer-storm-sun/

"Imagine if France, Germany, and Spain were completely blanketed in forests — and then all those trees were quickly chopped down. That’s nearly the amount of deforestation that occurred globally between 2001 and 2020, with profound consequences."

TIL about Eunice Foote. A US scientist and women’s rights campaigner born in 1819.

She was one of the first scientists to say that CO2 played a part in atmospheric warming. Several others independently reached the same conclusion, but Foote has been largely written out of history. For reasons we can probably guess.

#Webb Discovers #Methane, Carbon Dioxide in Atmosphere of K2-18 b

"The abundance of methane and #carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water #ocean underneath a hydrogen-rich #atmosphere in K2-18 b. These ... observations also provided a possible detection of a molecule called ... DMS. On #Earth, this is only produced by #life. The bulk of the DMS in Earth’s atmosphere is emitted from phytoplankton in marine environments."

A #fireball streaking across the #sky isn't a #UFO. It's a completely normal and natural phenomenon known as a #bolide—a mass (typically a rock) that burns up and disintegrates as it traverses #Earth's #atmosphere. Trying to associate these events with UFOs is misguided, and ultimately damaging to the legitimate study of unidentified arial phenomena.

Can you help point me to useful, ideally accessibly written / presented, material that looks at the limitations of carbon offsetting and the problem of leaving too much carbon in active systems?

(You can see why I may be struggling to find this stuff! Let me try to rephrase)

My limited understanding is that one of the challenges of #carbonSequestration is that it takes a loooooong time for carbon to be passed out of ecological systems and into geological ones. We’ve dug up and burned huge quantities of previously fossilized carbon in an extremely short period of time. If we really want to get atmospheric and oceanic carbon levels below safe thresholds, we need to re-fossilize carbon, not just store it temporarily.

Is that accurate? Where can I learn more? And what can I share with others to help explain it really simply?

Main motivation: help people understand that as important as carbon farming and forests etc are, we need an urgent and extreme reduction in new emissions, so we need both behaviour change (less demand) and electrification (cleaner supply) now.

Hello climate/weather/physics people - can you recommend a book on atmospheric spectroscopy that works for you? Doesn't need to be recent, but does need to cover the zoo of units used. Separate your absorbance from your absorptivity, like. #climatechange #physics #atmosphere

In cased you missed this chart, it shows the predicted increase of #CO2 and #temperature in the #atmosphere (black lines) compared to current observations (red & blue lines).

The prediction was made back in 1982 by ExxonMobil in private documents.

They knew since 1970s that #FossilFuels would lead to #ClimateChange with "dramatic environmental effects before the year 2050.”

Did they care ? Obviously no !

My @GFZ colleague @ingewiekenkamp is now on Mastodon 🎉

She uses #RemoteSensing to study the exchange of #carbon, #methane, and #water between Earth's surface and the #atmosphere.

From her preface: "It is my genuine belief that the only way we will be able to avoid the worst consequences of this emerging existential crisis is if we create a critical mass of people who demand the changes required. For that to happen, we need to rapidly spread awareness, because the general public still lacks much of the basic knowledge that is necessary to understand the dire situation we are in. My wish is to be part of the effort to change that."

A dense rainforest may be what first comes to mind at the mention of #photosynthesis.

Yet the clouds of #phytoplankton that fill the oceans are the major drivers of that process in nature.

The plantlike single-celled aquatic microbes generate more than 50% of the #oxygen in the #atmosphere, and they absorb nearly half of the carbon dioxide, converting it into the glucose, fats, proteins and other organic molecules that nourish the food web of the #oceans.

"What makes these most recent temperature spikes so alarming is that they’ve occurred before a forecast #ElNiño event in the Pacific, rather than during one."

"Since 1971, about 89 % of the excess heat in Earth’s climate system has been stored in the ocean (with 6 % on land, 1 % in the atmosphere, and about 4 % going towards melting ice on land and sea)."

When the #oceans give up a little heat the #atmosphere heats up a lot.

This is worth repeating: nearly all the heat from #GlobalWarming goes into the oceans, so water temperatures have been rising steadily.

On top of that there is an #ElNiño developing. This is where the Pacific Ocean burps up heat.

But oceans and the #atmosphere are all connected, so what happens in the Pacific doesn't stay in the Pacific. Weather patterns, winds, pressure systems are affected all over the planet.

With the dense #smoke from #Canadian #wildfires blanketing #NYC today, I've seen a bunch of comments from #Americans along the lines of "Wow, how bad must in be in Canada?"

This is counter-intuitive, but I'm in the Canadian #prairies. There are wildfires across northern #Saskatchewan, #Alberta, and #BC. And we haven't had any smoke here for weeks.

The smoke can go up into the #atmosphere, drift a long way, and then be pressed down to the ground again by a high-pressure system.

The Upper Atmosphere Is Cooling, Prompting New #Climate Concerns

A new study reaffirming that #ClimateChange is human-made also found the upper #atmosphere is cooling dramatically because of rising #CO2 levels.
...But the new discoveries about the scale of cooling aloft are leaving atmospheric physicists with new worries — about the safety of orbiting #satellites, the fate of the #OzoneLayer, the unanticipated turmoil on our #weather below.

Earth's atmospheric layers. NOAA / Yale Environment 360

The Earth’s atmosphere has a number of layers. The region we know best, because it is where our weather happens, is the troposphere. This dense blanket of air five to nine miles thick contains 80 percent of the mass of the atmosphere but only a small fraction of its volume. Above it are wide open spaces of progressively less dense air. The stratosphere, which ends around 30 miles up, is followed by the mesosphere, which extends to 50 miles, and then the thermosphere, which reaches more than 400 miles up.

Golden Gate in the Fog II

By the time I got close to the bridge the fog had at times completely hidden it. nearly swallowed it.

This image was captured on the waterfront of the San Francisco Bay looking westward along the shoreline towards the Golden Gate Bridge. 
In the foreground are some pilings and right behind that is a pier that sits out in the water of the bay. There is a small workshop, storage building on the pier that has white walls and red tile roof. 
Behind the pier is a fog bank that runs up to a little over midway in the image. This fog bank obscures the bottom portion of the Golden Gate Bridge only leaving the upper portion of the south tower visible along with some of the support cables.
