I speak about climate futures, mitigation and adaptation in the face of the climate crisis. 🇿🇦

Did you know:

Japan’s has had a long-standing fixation with sakura (cherry blossoms) in fact cherry blossom records date back to 812! This gives us a data set spanning 1211 years.

This has proven to be a treasure trove for scientists because they have been able to use this data to track a heating planet. (Pictured)

As a result cherry tree blossoms in Japan have been included in the “instrument dashboard” tracking our heating world.

Another breathtaking display after a passing storm 💜

Interesting question. Extreme temps (hot & cold) are but one of the causes of climate related deaths, others are wildfires, storms, floods, food shortage, disease etc.

With regard to extreme temp deaths this is latest research on the topic https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(21)00081-4/fulltext#tbl1

High level extreme cold is causing more deaths at the moment but heat related deaths are rising, especially related to the observed increase of humidity over land which is impacting wet bulb temperatures significantly in many places.

But heatwaves create havoc on the entire system. Check out this graphic where researchers mapped out the impact of the 2022 Indian heatwaves.

The question is what happens when the grid collapse under an air-conditioning strain? As was narrowly averted last year:

About 182 weather stations in Japan are reporting heat records for March. What will summer bring to this region?

Some parts of the world are going to experience dangerous wet bulb temperatures (https://en.m.wikipedia.org/wiki/Wet-bulb_temperature) as we continue to heat.

This graphic is an indication where these areas will be. Essentially, at the top end of the heating scale, these places will become uninhabitable as a result of the high temperatures combined with high humidity.

This from the latest IPCC synthesis report. They highlight the difference between the Fifth Assessment Reports (AR5 - 2014) and the Sixth Assessment Reports (AR6 - 2022)

Due to

1) Current impact observations,

2) Improved understanding of the climate system and

2) New knowledge on our collective vulnerability

They make this adjustment in their risk assessments: “Risk levels become high to very high 𝙖𝙩 𝙡𝙤𝙬𝙚𝙧 𝙡𝙚𝙫𝙚𝙡𝙨 𝙤𝙛 𝙜𝙡𝙤𝙗𝙖𝙡 𝙬𝙖𝙧𝙢𝙞𝙣𝙜.”

Simply put this means greater impacts sooner than imagined.

There should be no delay in our collective actions to mitigate against this getting a lot worse (ie being unable to keep warming well below 2°) and adapting to impacts we are already committed to.

Climate literacy is now really a non negotiable.

If you think about it - if you go to dinner with friends the conversation around the table isn’t recorded, bar maybe a picture or two. When dinner is done the conversations live in our memories only.

I think ephemeral social media captures that vibe. Very little has to live on as record of what was actually said in that moment in time.

We are going to go through some things.
