Annual mean temperature anomaly from 1940 to present with three milestone crossings annotated. A dashed projection line suggests 2.0C could be reached around 2038 if the current pace continues.

Annual mean temperature anomaly from 1940 to present with three milestone crossings annotated. A dashed projection line suggests 2.0C could be reached around 2038 if the current pace continues.

9/ A sanity check, forget the lag model entirely.
The annual mean took 30 years to go from 0.5Β°C to 1.0Β°C, and 14 years to go from 1.0Β°C to 1.5Β°C.

If the next 0.5Β°C takes the same 14 years, we reach 2.0Β°C around 2038.

Not 2050.

Are we prepared for that?

Efficiency, optimization, productivity: celebrated as universal goods.

These ideas are especially influential in economics, engineering, and computer science.

But what if they reshape our systems and lives in ways we rarely notice? 🧡

Nobel Peace Prize 1986 The Nobel Peace Prize 1986 was awarded to Elie Wiesel "for being a messenger to mankind: his message is one of peace, atonement and dignity"

"We must always take sides. Neutrality helps the oppressor, never the victim. Silence encourages the tormentor, never the tormented. Sometimes we must interfere."

March 11 marks the 15th anniversary of the 3rd-largest seismic event ever recorded, the magnitude 9.1 Tōhoku earthquake and tsunami. Recovery from this devastating event is still ongoing. Research into ways to make our society more resilient to nature's unpredictability continues.

Grief, anger and lack of trust expressed in community meetings on Nature Restoration Plan Plan must have clear and enforceable targets, says advisory committee

The vast majority of the Irish public feel distress, sadness, anger, grief, fear, despair, guilt, frustration, and worry at nature loss and environmental decline.

Why is this never reflected in actual government policy???

What I always find most fun about energy commentary is the sneering at those poor misguided do-gooders who think that maybe burning ever more fossil fuels in the midst of a worsening global climate crisis is a bad idea.

The warming trend is unmistakable, and it's accelerating.

The rolling average has gone from 0.25 in 1940 to 1.5Β°C.

"In the USA, discourse and politics are undermining civil rights and dismantling science. Scientists can no longer afford neutrality. It is time for us to take collective political action to defend academic freedom and the communities that science is meant to serve."

For the first time ever, the world's daily average temperature was 2.0Β°C above pre-industrial levels

Here's what the data says about when that becomes the annual norm, & whether it's coming sooner than anyone expects🧡

I am stuck on this: so many people in this world are not living a decent life, go hungry, feel unsafe, and are at risk in other ways. Instead of doing everything possible to help them, why do those with the most power instead do everything they can to harm them? It (still) makes no sense.
