In der Klimawissenschaft ist ein Kipppunkt definiert als "eine kritische Schwelle, jenseits derer sich ein System neu organisiert, oft abrupt und/oder irreversibel" (Lenton et al., 2008). Hier sind 10 #Kipppunkte, die für uns zunehmend an Bedeutung gewonnen haben.
"Einige der im #IPCC-Bericht erörterten abrupten Klimaänderungen und Kipppunkte könnten schwerwiegende lokale Klimareaktionen nach sich ziehen, wie extreme Temperaturen, Dürren, Waldbrände, Verlust der Eisschilde und Zusammenbruch der thermohalinen Zirkulation.
Es gibt Hinweise auf abrupte Veränderungen in der Erdgeschichte, und einige dieser Ereignisse wurden als Kipppunkte interpretiert (Dakos et al., 2008). Einige davon sind mit bedeutenden Veränderungen des globalen Klimas verbunden, wie z. B. die Interglaziale im Quartär (vor 2,5 Millionen Jahren) und die rasche Erwärmung während des thermischen Maximums im Paläozän und Eozän (vor etwa 55,5 Millionen Jahren; Bowen et al., 2015; Hollis et al., 2019).
Solche Ereignisse veränderten das planetare Klima für zehn- bis hunderttausende von Jahren, aber mit einer Geschwindigkeit, die tatsächlich viel langsamer ist als der projizierte anthropogene Klimawandel in diesem Jahrhundert, selbst wenn es keine Kipppunkte gibt" (IPCC, 2021).
One of the first storms of #monsoon passed close last night and created a #sunset that looked like fire in the air! I wasn't able to post it last night, so I'll use it to wish a good night to all. May the monsoon come quickly and drench the whole state of #Arizona
Human degradation of the #Amazon – by land clearance, fire, logging and mining – is pushing that system towards a tipping point, after which drier conditions would be expected to cause an abrupt “regime shift” in the rainforest, which would be unable to sustain itself and transport moisture."
🌧️ To balance all my whining about no rain, I must be sure to acknowledge 10 whole minutes of moderate shower this evening. Enough to dampen the ground and create a few puddles. Proverbial drop in the bucket, but since #Arizona had basically no #monsoon at all this year, every one of those drops counts. 💧 😍
"Urban #flooding has become a recurring and alarming issue in Indian cities every #Monsoon.
Implementing comprehensive #StormwaterManagement plans to tackle flood risk and promoting sustainable #water management in urban areas, especially during the Monsoon season, is crucial."
⛈️ Ahhh...the dark clouds and thunder & lightning came SO CLOSE in the last hour. But dissipated right before reaching us. 😭 Maybe tomorrow! At least the breeze from it cooled things a little.
Maybe a first in Phoenix but 2 different weather apps a bit ago warned “Severe thunderstorm in 22 minutes. 100% chance of rain.
It does look pretty intense outside with a LOT of lightning and thunder. This may actually pan out! I’m too indisposed right now to do my planned rain dance. But if anyone else is so-inclined, I’d appreciate it. @grumpywitch @Manny #Phoenix#Monsoon#Arizona
"n K-P, the consequences of #GlobalWarming and #ClimateChange are evident in the changing of the #monsoon season, which now falls at a time when the #strawberry cash crop, a speciality of Charsadda, is to be cultivated."
".. unusual rains .. destroyed approximately 80 per cent of the fruit’s crop, leaving farmers in a deplorable state... "
I got quite excited about this photo, developed it to my liking, and then wondered how I missed it back then — only to find out that I had already picked a horizontal orientation version for my portfolio. 🤪
#Rain!!! 2x in a week, and lasting more than half an hour now. It's cause for huge celebration. 🎉😃🎈 Could it be an actual piece of #Arizona#monsoon?? 🤞
⛈️All these small, fast-moving storms going by us on every side. So near and yet so far!!
😬🤦♀️ 🤷♀️ I'm happy for whomever is getting the rain, but hope it's our turn soon.
Kerala headed for a drought-like situation after 4 continuous years of heavy rain, landslides, floods (thesouthfirst.com)
The lack of rain and increasing heat has severely affected power generation and agricultural activities in the state.
