Methane from landfills is detectable from space – and driving the climate crisis
"MethaneSAT joined more than a dozen similar satellites now in orbit, scanning the Earth for pollution and feeding that information back to scientists, policymakers, industry and the public."

Over-polluting and under-reporting: A look inside Russia’s dirty fossil fuel industry.
NordStream leaks... "Although these leaks were comparable to the yearly emissions of around 9 million cars, they were equivalent to only around one to two days of the global fossil fuel industry’s normal methane emissions."

Methane (CH₄) is a potent greenhouse gas. Here are the most recent monthly observations (upper right corner)... 📈

April 2023 - 1922.2 ppb
April 2022 - 1909.4 ppb

ariadne,

@ZLabe is not just a more potent than it is far more potent. Explained well in this article from
"Over 20 years, the methane would trap about 80 times as much heat as the CO2. Over 100 years, that original ton of methane would trap about 28 times as much heat as the ton of CO2.

Trancik says environmental organizations and climate models, including those used for major studies or international accords like the Paris Agreement, consider the warming effects of methane over a hundred years. Why this number, when methane is far more damaging in the short term? In part, Trancik says, it was an “accident of history.” Decades ago, when scientists began to tackle the complicated task of comparing different greenhouse gases, most climate projections were looking out to the year 2100—about 100 years in the future."

I’d like you to watch a short superb animated film about the feedback loops likely to result in catastrophic climate breakdown.

This video first aired in 2008. Keep that date in mind.

At 8:20, the narrator says:

“We need to recognize that there is a huge question mark over whether governments and corporations are capable of responding to this threat in the time we have left. They've had 20 years already, and still have less than nothing to show for it.”

Okay, they were doing badly at the time, but are they doing better now? What have governments and corporations done during the last 15 years, since 2008, to respond to the dire threat we all face?

Back then, CO2 levels in the atmosphere stood at 385 parts per million. Today, we’re at 420 ppm, and climbing. In fact, the annual rate of increase — current year compared to previous year — has ALSO been increasing. [see graph in comment below]

We’re pumping greenhouse gases into the air faster and faster instead of slower and slower like we would if we lived in a sane world.

Plus, as of 2008, the planet had only warmed 0.8° Celsius above the 1850-1900 pre-industrial baseline. But now we’re up to 1.2°C and rising. That’s a global heating gain of 50% in just 15 years!!

No wonder climate scientists are scared of what’s coming.

So, let me ask you — what are governments and corporations doing in response to the threat of climate breakdown?

  1. Almost nothing
  2. Next to nothing
  3. Nothing
  4. Less than nothing

Whichever answer you chose, you’re right!

Diese Woche fand ich das hier besonders spannend: Aus dem All wurde entdeckt, dass in ungenutztes in die Atmosphäre abgeblasen wird. Früher wurde das abgefackelt, was auch nicht schön ist, aber wenigstens das abbaut. Das ist aber sichtbarerer und hier geht's ums Verheimlichen.

Der Fund zeigt, welche unerwarteten Folgen schon eine Ächtung haben kann:

Satelliten finden "irrsinnige" versteckte Methanleaks

Das passiert auch bei verlassenen Bohrlöchern im Ozean. Hier 🇩🇪 https://www.geomar.de/news/article/neue-studie-bestaetigt-umfangreiche-gasleckagen-in-der-nordsee haben Forscher vom in Kiel 2020 publiziert, wieviel in einem 20000km2 Gebiet aus 48 Löchern sprudelt.
Das Methan sieht man nicht vom Satellit aus. Darum wird Shaming nicht gemacht wie in Turkmenistan jetzt.

Nur wenn aus weniger als 200m Tiefe sprudelt, erreicht es die Oberfläche und die Atmosphäre. Die Löcher in der Nordsee liegen wohl tiefer.
Den Ozean mit Methan versauern lassen und dabei Sauerstoff aus dem Tiefenwasser klauen? Egal.

Ne ganz neue Studie hat 14000 alte, unverschlossene Ami-Löcher im Ozean untersucht und Kostenvoranschlag gemacht: 30 Milliarden $ zum Verschließen. 88% der offenen Löcher gehören den fetten BigOil-Firmen...
Von diesen Löchern sind auch welche im flacheren Ozean-Wasser und das erreicht die Atmosphäre.
