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

Very sobering from Prof. Bob Watson as the impacts mount at +1.28°C of warming.

The #Mediterranean is on fire at the moment.

⚠️ Early Warning

“The ongoing scorching heatwave across Europe and Turkey’s S and SE parts will finish with a deep upper wave emerging from the west, producing a major severe weather event across the Alpine region, northern Mediterranean, and central Balkan countries.”

Tourism on a heating planet.

The economic impact of where we are headed is coming into focus and this at 1.28°C of warming.

Heatwaves, fires & drought do not go hand in hand with having a relaxing summer holiday.

The truth is we are completely and utterly unprepared for a world at +1.5°C

We can hardly cope with the current +1.28°C

As heat domes sit over Asia, Europe and the US, this is a critical piece of #ClimateLiteracy regarding #Heatwaves

“Overnight minimum temperatures are expected to reach new highs. This is concerning because repeated high night-time temperatures are particularly dangerous for human health because the body is unable to recover from hot days, leading to increased cases of heart attacks and death. Whilst most of the attention focuses on daytime maximum temperatures, it is the overnight temperatures which have the biggest health risks, especially for vulnerable populations.

“We need the world to broaden its attention beyond the maximum temperature alone. In many locations where the maximum is reaching into the high 40°Cs and higher, the temperature may still be near 40°C at midnight. In these circumstances, the minimum temperature is more important for health and failing critical infrastructure during extreme heatwaves.”—John Nairn WMO extreme heat advisor.

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.

Which will it be?

#ClimateLiteracy #ClimateCrisis #Leadership

We are at +1.27°C of warming. And CO2 atmospheric concentrations at at 424.68 ppm (June)

The resulting extreme weather events are now so common they hardly make the news anymore.

This is #Zaragoza, #Spain, on Thursday July 6th after an extreme precipitation event caused a flash flood trapping people in their cars as roads turned into raging rivers.

We are in a climate emergency.

Summary of my thoughts regarding Threads UX:

1. Easy to get started ONLY if you have instagram. I don’t think there’s any other option to sign up. This feels weirdly gated and unpleasant.

2. An option to easily import info from instagram seems smart and convenient

3. The overall layout is clean, minimal and easy to familiarize with. I like that there are not too many options to overwhelm the sense.

4. The UI seems to encourage mindless engagement. As Mike Brock stated, it feels very much like TikTok - and endless stream of consumption, encouraging you to doom scroll forever. The feed seems to prioritize media content (especially video). I did not see many photos. Of course, this is mixed in with other short and shallow commentary.

5. I saw very little engagement in terms of replies. Most engagement is likes. This confirms my belief that Threads is a zombie doom scroller’s app. It seeks to extract your time, preferences and information and cares little about actual conversations. You have to have a big account with many followers to see much in terms of replies. Nostr is significantly better at meaningful interactions, but this could be in part because we’re so small.

6. The reload animation is very delightful. I like the micro interactions on the like button and the reload. Hope all nostr clients consider micro interactions.

7. The threading of replies is simple and intuitive. Obviously biased, but feels almost identical to Snort reply system I designed a while back, but faster / smoother (I think this is super important and what sets Threads apart).

8. The video in the feed does not feel as immersive as Damus, but works well.

9. I like how Threads handles multiple images in an easy to swipe gallery that spans the entire screen. Feels very clean and smooth.

10. The consistency between the web version and the app version is great and I think it’s important in onboarding people. Right now we have Damus and Amethyst ( I believe) both linking out to Snort and this could be a very confusing experience for users. Maybe we could make a more generic client that can be used for linking without any branding or particular styling?

11. Threads offers plenty of sharing options. The share button is within the reactions menu which is great as this minimizes any additional clicks. Many nostr clients hide the share button (primarily because we have an extra one for zaps which already makes everything look busy). We should think about how to make sharing more prominent.

12. Threads has an invite friends feature which I also like. I hope we can think about ways to make inviting more user friendly and more obvious (maybe even gamified a bit). There’s no reason a client could not give out a badge for people who invite x number of people for example.

13. One strange thing is that there are no hashtags on Threads. It is a person search and follow app. You literally cannot search for topics. This just further reinforces my belief that this app is made for maximum consumption and doesn’t really care if it’s good for humanity. Maybe it’s a planned feature for later? Who knows.. I suspect not.

14. The app over is very fast and snappy. This makes for a pleasant browsing experience and encourages to keep scrolling. There’s very little noticeable lag of any kind. I think performance is a key thing here and we can all take away from that. How do we make nostr apps smoother?

Overall I felt that the app UX and UIs are excellent. You can tell a team of professional designers poured their hearts and talent into this app.

However, the app design choices seem to push the content into the mindless doom scrolling generic category where engagement is not really encouraged or valued. To me this feels like a net negative to society.

I honestly don’t know how Zuck can sleep at night knowing this is what he is enabling, but appreciate the work by done Meta designers (however negative the consequences, you have to give them credit for creating a very smooth, simple and intuitive experience). nostr:note198vhslkxp2f6xyuyshzh777u7gtyawqr4mle2kvxs9gp6x0hajzsvw688s

About 13

Image Context.

2016 & 2020 were tied the hottest years on record.

On Aug 14, 2016 a daily global average 2m air temperature record was set at 16.92°C

On July 11, 2020 the highest average was 16.82°C

On Mon July 3, 2023 we broke the 2016 record with a new high of 17.01°C

Yesterday, Tuesday July 4, 2023👇🏻

🧪

Yesterday we broke a record.

We recorded an average global temperature of +17.01ºC for the first time since instrumental records began.

With another month or so of heating to go before it turns down again 2023 may become the warmest year on record, beating out 2016.

The impacts of the #climatecrisis are being felt in #China there is no doubt about that:

"China will face multiple natural disasters in July, including floods, severe convection weather, typhoons and high temperatures, authorities warned."

So basically the same as Twitter

With your re acidification — and here is where we stand on that front:

“Prior to the Industrial Revolution, average ocean pH was about 8.2. Today, average ocean pH is about 8.1. This might not seem like much of a difference, but the relationship between pH and acidity is not direct. Each decrease of one pH unit is a ten-fold increase in acidity. This means that the acidity of the ocean today, on average, is about 25% greater than it was during preindustrial times.” (https://www.epa.gov/ocean-acidification/understanding-science-ocean-and-coastal-acidification#:~:text=Solutions%20with%20low%20pH%20are,ocean%20pH%20is%20about%208.1.)
