Now that the Actuaries have woken up to the reality bearing down on us like a freight train, will the rest of us too?
The consequences of going to a permanent +1.5°C of warming by 2030 and then +2°C by 2050 are going to push many countries to the brink of collapse.

Wet Bulb Temperature risks 2023-2050:
“Even heat-adapted people cannot carry out normal outdoor activities past a wet-bulb temperature of 32°C (90°F), equivalent to a heat index of 55;°C (131°F). A reading of 35°C (95°F) – equivalent to a heat index of 71°C (160°F) – is considered the theoretical human survivability limit for up to six hours of exposure.”

Take a look at these two images.
The first is from NASA and when sharing it they state “July 2023 was the hottest month globally since modern recordkeeping began in 1880, measuring at 1.18°C (2.12°F) above NASA - National Aeronautics and Space Administration’s 1951-1980 baseline average.“
we
The second image is from ECMWF and in its release they state “The month (July) is estimated to have been around 1.5°C warmer than the average for 1850-1900.”
Who’s right is it +1.18°C of warming or +1.5°C
We
They are both right. The difference is NASA is using 1950-1980 as the baseline and ECMWF is using 1850-1900 as their baseline.
In the work we do (see my cover image) we use the ECMWF baseline of 1850-1900.
Using that baseline, 2023 so far, has warmed +1.28°C
We are expected to cross the +1.5°C of warming by about 2030 and +2°C by 2050, the impacts of which are now coming clearer into view. https://cdn.nostr.build/i/bcb44bc5941730dbf4d2a05366b9b9c014106cf9f21b191334027311cdd45356.jpg https://cdn.nostr.build/i/deef50e70ce8a62bba808972c59681d4fe333e9155fdd4c41a9e8eff85db2458.jpg

#EarlyWarning
In the next 27 years, on our current trajectory, everyone and everything alive on earth will first experience a world at an average global temperature of 15.3°C (+1.5°C above preindustrial average of 13.8°C) and then a world at 15.8°C (+2°C above preindustrial)
Both these states will unlock climate chaos only seen in movies.
Forget about 2100.
The clear and present danger is NOW for billions of people, animals and plants.
What we do TODAY about turning off the emissions tap that is pouring GHG’s into the atmosphere is going to determine if we can buy sufficient time to adapt or not.

Whether you use the HadCRUT5 or ERA5 data sets one thing is crystal clear we are very close to making 15.3°C (that is +1.5°C above the preindustrial average of 13.8°C) the new global average temperature.
There are horrors that await this shift.
Speaking of impacts at the current 15.03°C (+1.28°C above preindustrial) Prof Bob Watson said, referring to impacts at the poles: “I am very concerned. None of the observed changes so far (with a 1.2C temperature rise) are surprising. But they are more severe than we predicted 20 years ago, and more severe than the predictions of five years ago. We probably underestimated the consequences.”
With each incremental increase we move more and more of life on earth beyond adaptation limits.
We are in an emergency.

There is absolutely no way to “negotiate” with the physics of our dumping 39 Gt CO2 into the atmosphere per year.
This behaviour results in accelerating climate change as can be witnessed by the rise in the global average temperature to +1.27°C above pre industrial averages.
If we continue to treat earths atmosphere as a CO2 sewer we will all but ensure catastrophic climate change within the next 70 years.
We understand the physics. As a result we also understand what we need to do to avert catastrophe.
Here it is: We need to go from emitting 39 Gt CO2 per year to 19 Gt CO2 by 2030.
This means we need to look at EVERY emission source and avoid it or shift to non-carbon emitting energy sources.
If your business burns fossil fuels to generate revenue it would be prudent for the long term survival of your business to decouple revenue generation from the need to burn fossil fuels as a matter of urgency.
If you don’t do this voluntarily be assured that you will be forced to do so in the near future.
Voluntary transition is WAY less painful than forced transition as Air France-KLM just discovered.

The heating ocean and melting ice, a hallmark of the evolving climate crisis, are causing seas to rise. (Global average sea level has risen 21–24 centimeters since 1880. In 2021, global sea level set a new record high—97 mm (3.8 inches) above 1993 levels.)
There are many places where retreat is the becoming the only option, one of these places is Khun Samut Chin, just outside of Bangkok.

How do we know that the #ElNino phase has arrived?
We use our instruments:
“Satellite- and ocean-based measurements of sea surface temperature are one way to detect the arrival of El Niño. Its signature also shows up in satellite measurements of sea surface height, which rises as ocean temperatures warm up. That’s because warmer water expands to fill more volume, while cooler water contracts.
The [image] depicts sea surface height anomalies across the central and eastern Pacific Ocean as observed from June 1–10, 2023. Shades of blue indicate sea levels that were lower than average; normal sea level conditions appear white; and reds indicate areas where the ocean stood higher than normal.”

Today the Beijing Meteorological Bureau upgraded the city to a level red warning, the highest heatwave warning, as temperatures soared to just above 41°C
Beijing is home to 22 million people, who were urged to take emergency measures to prevent heatstroke. Stop outdoor work in the open air. Take protective measures for the elderly, the weak, the sick and the young and pay special attention to fire prevention.

⚠️ Early Warning — Dangerous Wet Bulb Temperatures forecast for parts of Texas on Friday.
Reminder: The actual max wet-bulb temp is lower than 35°C — about 31°C wet-bulb or 87°F at 100% humidity — even for young, healthy individuals. For older populations, who are more vulnerable to heat, it’s likely even lower. (See https://journals.physiology.org/doi/full/10.1152/japplphysiol.00738.2021)

For every °C that Earth’s atmospheric temperature rises, the amount of water vapor in the atmosphere can increase by about 7%. The more water vapor that air contains, the more energy it holds, fuelling intense storms, particularly over land resulting in more extreme weather events.

2) Along coastlines
3) Near ice or seasonal rivers

We are in brand new territory:
“When you have an El Niño occurring on top of the long-term warming trend, it’s like a double whammy.”—Katharine Hayhoe, chief scientist at The Nature Conservancy.
Any business that does not, as a matter of urgency, become climate literate, is going to experience considerable pain.
“Dartmouth scientists estimated that the 1997-1998 El Niño led to $5.7 trillion in lost gross domestic product the following five years. Their modeling estimates that by the end of this century, El Niños will have blocked some $84 trillion in GDP.”
Climate disruption is real and is coming at us at break neck speed.

This is correct.
We have just come out of a longer than normal cooler La Niña period.
We are now moving into the warmer El Niño phase. The last El Niño event we had was in 2015/16 which was described as a “super El Niño” as a result of the heat it created.

2023-06-11 04:42:21 UTC

Climate Literacy:
During an El Niño event, the trade winds that normally blow from east to west across the tropical Pacific weaken or even reverse direction³⁵.
This causes the warm surface waters that are usually found in the western Pacific along the coasts of Ecuador/Peru/Chile to spread eastward along the equator¹³⁵. As a result, the ocean heat that is normally stored in the western Pacific is released to the atmosphere in the central and eastern Pacific²⁴. This affects the global weather patterns and climate¹²³⁵.

#ClimateLiteracy: The 1.5° limit applies to the average temperature over a year, and passing it would mean that the average will have been sustained for several years.
That said, we have crossed the 1.5°C anomaly on hundreds of individual days, after which it has fallen back below 1.5°
Most of these days occurred in 2016 & 2020.
Now as the heat begins to load up as a result of the maturing El Niño we will see many individual days again cross 1.5°
For example look at this. In 2023 we breached 1.5° on March 6-11 and again yesterday (June 9th) https://nostr.build/i/d7c43f760059d1c6f1f08af053c66757400bad01bba349f4db7203b569967fca.jpg

Cryosphere Early Warning
- Reference glaciers (for which we have long-term observations) experienced an average thickness change of over −1.3 metres between October 2021 and October 2022. This loss is much larger than the average of the last decade. The cumulative thickness loss since 1970 amounts to almost 30 m.
- The European Alps smashed records for glacier melt due to a combination of little winter snow. In Switzerland, 6% of the glacier ice volume was lost between 2021 and 2022 – and one third between 2001 and 2022.
- The Greenland Ice Sheet ended with a negative total mass balance for the 26th year in a row.
- Sea ice in Antarctica dropped to 1.92 million km2 on February 25, 2022, the lowest level on record and almost 1 million km2 below the long-term (1991-2020) mean.
- Arctic sea ice in September at the end of the summer melt tied for the 11th lowest monthly minimum ice extent in the satellite record.
- Global mean sea level reaching a new record high for the satellite altimeter record (1993-2022). The rate of global mean sea level rise has doubled between the first decade of the satellite record.

We *have* to talk about adaptation as a result of the warming we are *already* committed to.
But we need to understand that we are already brushing up against the limits of adaptation. (See pic)
Which is why we also *have* to talk about mitigation because if we don't slam the brakes on emissions our ability to adapt at all will fade into the rearview mirror.

I think part of answering what Nostr’s pull could be is finding a way to decouple its strong perceived connection to Bitcoin.
There many many people that will avoid it a all costs because of that.
Both BlueSky and Mastodon are way more diverse which makes it more appealing for people to join.
Here seems very niche. You can see this when looking at the Nostr firehose vs the BlueSky firehose for example.
I am not sure if changing this perception is even possible.
