Earth trapping much more heat than climate models forecast – and rate has doubled in 20 years
Burning coal, oil gas added more than 2 trillion tonnes of c02 and other greenhouse gases to atmosphere
These trap more and more heat, preventing it from leaving
And this is the result
Scientists say we’re heading for 2-3C by mid century.
Risk assessors & insurers say this means 2-4 BILLION deaths.
Governments & the media say pretty much nothing.
We are not the owners of Mother Earth. We are just her temporary custodians.
And we are failing at our job.
Say NO to deforestation in the Amazon and Congo Basin. #ClimateAction
Update: This "Super El Niño" will be perhaps the strongest in 500 to 1000 years, and could legitimately be the most extreme global weather or climate event experienced by humanity since the invention of the printing press. Only more extreme situation is a volcanic winter.
Just because you lobbied to have the man who issued the war crimes taken down doesn’t mean the war crimes disappear or your guilt is assuaged. You will not outrun justice. You will not lobby history. You are a murderous maniac Benjamin Netanyahu. You will always be remembered as such.
In recent weeks, there has been a remarkable surge in large, intense, fast-moving, and unfortunately in many cases destructive/deadly wildfires in multiple Northern Hemisphere regions spanning a wide range of climates & ecologies, but they all share one key commonality. [Thread]
Live at Noon Pacific Time on Wed, Jul 29: I'll discuss the upcoming prolonged, and potentially intense, SW US heatwave (inc. links to Pacific hurricane), & also recent surge in severe wildfire activity across Northern Hemisphere amid ongoing record heat. https://t.co/BfB7V27G4t
La lA es una tecnología que desde su concepción carece de ética.
En las instituciones y los medios que la han adoptado irresponsablemente, no se habla de todos los impactos negativos que con estudios serios se han comprobado; principalmente el impacto socio-ambiental.
En los últimos años la UNAM ha fomentado el uso de la lA entre docentes y estudiantes con ponencias, pláticas, cursos, diplomados, manifiestos, etcétera; sin haber hecho, ANTES, la chamba de poner en la balanza la cuestión ÉTICA en su uso y aplicación en la academia.
La #UNAM informó que revisará a detalle los resultados de los #exámenes de admisión para licenciatura que este año por primera vez se realizaron en línea, tras las quejas y señalamientos de los aspirantes por presuntas irregularidades durante el proceso.
El rector Leonardo Lomelí instruyó la elaboración de un informe que reúna datos sobre cada etapa del proceso de admisión. Además, se comprometió a conformar una comisión técnica integrada por especialistas universitarios de distintas disciplinas, quienes analizarán la información sobre la aplicación de los exámenes y los resultados del concurso de selección.
Power blackouts are spreading across parts of North Africa as temperatures soar above 40°C. This is why extreme heat is so dangerous. When the grid fails, millions can lose air conditioning, refrigeration and water pumping. Climate change is becoming an infrastructure crisis.
Canada is on fire.
Europe is on fire.
The Amazon is on fire.
Cities are breaking heat records.
Rivers are drying up.
Other countries are drowning in floods.
Storms are getting stronger.
Seasons don’t feel like seasons anymore.
And somehow…
climate change is still a debate.
🚨 Si la presidenta @Claudiashein aprueba el fracking romperá su compromiso con los pueblos indigenas.
Porque esta técnica atravesaría los pueblos Chichimeco, Kikapú, Nahua, Otomí, Pame, Tepehua, Totonaco y Téenek.

"Just put the fires out!"
Ever seen a boreal wildfire? I have. I used to fight them.
When fire behaviour becomes extreme, you're not getting close to them.
The radiant heat from a crown fire is face-melting from hundreds of metres away.
All attempts at direct attack will fail, because dropping water on it becomes akin to trying to spit on a campfire...it evaporates before it even hits the flames.
Additionally, reduced visibility, high winds, and turbulence makes aerial attack hazardous.
As a wildland firefighter, I've been extracted off of wildfires twice as our fires blew up, both times having our gear burned over. We returned to find firehoses and metal melted into the ash.
I've seen fireballs launched hundreds of feet high, and fires intense enough to produce lightning, influencing the weather around them. I've seen wildfires grow to the size of a major city in a short period of time.
So no, we can't just put the fire out.
Not being able to stop such a natural process is a truly humbling feeling.
We have the technology and the policy roadmap to replace fossil fuels with green energy extremely rapidly.
The only thing stopping us is a handful of billionaires getting rich while our world burns.
People in France are literally rescuing fish before they die as rivers disappear completely. After 3 consecutive heatwaves, 16% of French rivers have dried up. Once-living riverbeds are becoming ecological deserts/cemeteries. The birds are disappearing also due to lack of food.
Remember - the wildfires, the droughts, floods, heatwaves happening across the world are within "safe" climate change (1.2°C warming). We are on course to double that.
No time to waste. #ActOnClimate#climate#energy#renewables
