In absolute terms, both Mastodon and Instagram punch above their weight. Twitter and LI are just below. And FB is, no surprise, extremely low.

@Humpleupagus sure, here it is. You can see that Mastodon and IG are punching above their weight, Twitter and LI are proportional, and FB is very low.

On Monday, I wrote an essay about climate and biodiversity for Scientific American. I tracked proportional engagement, calculated as (likes + shares + comments)/followers, over six social media platforms.

The winner? MASTODON, by a landslide.

Second place? INSTAGRAM. It's harder to share posts on IG, but lot of people like things there!

The loser? FACEBOOK, also by a landslide.*

* On Facebook, I've been shadow-banned since August 2018 when they listed clean energy and climate as "socially sensitive topics" so my page there stopped growing 6 years ago and now only about 1% of my followers there ever see my posts. It's actually too bad, because that's the platform where I reach the most conservative audiences through their connections to friends and family. So even though it's dead last, I still persist.

Within my own lifetime, the last 50 years, nearly 80% of the CO2 emissions from burning fossil fuels, and close to 60 percent of all GHG emissions have been released.

There's been a near 70% decline in populations of existing wildlife species; and across the 8 million animal and plant species on earth, the human-induced extinction rate is now estimated at tens to hundreds of times greater than natural rates.

#BiodiversityDay reminds us that the profound crises we confront are just different sides of the same coin, and that our future is truly in our hands. The planet doesn't need us: we are the ones who rely on it for all the air we breathe, the water we drink, the resources we need. That's why our choices matter more today than ever: the path to a better future lies through these crises.

We've known for a long time that climate change is increasing the area burned by wildfires across western North American. Now, a new study by @ucsusa shows that emissions from the world’s 88 largest fossil fuel companies and cement makers are responsible for 37% of the forest area burned in the western U.S. and Canada since 1986. https://e360.yale.edu/digest/fossil-fuel-companies-western-forest-fires

The IPCC AR6 Synthesis Report released today. Here are the key takeaways and figures.

First, climate change has already caused widespread and substantial losses to almost every aspect of human life on this planet, and the impacts on future generations depend on the choices we make NOW.

We are wrapping an extra blanket of heat-trapping gases around our planet, the only home we have. And just like you would if someone snuck into your room and put an unneeded blanket on you, the earth is heating up. #GlobalWarming explained in 75 seconds. https://vimeo.com/151923918

In 2022, the US experienced 18 billion-plus dollar weather and climate events. Over the last ten years there's been one event on average every 3 weeks: compared to the 1980s when there was one every 4 months. https://www.ncei.noaa.gov/access/billions/

Yes, these calculations account for inflation over time. Yes, there is more valuable infrastructure now than in the 1980s. And yes, climate change IS making these events worse. See: https://twitter.com/KHayhoe/status/1167851841041981440

This is one reason why the transition to clean energy is estimated to save (not cost, but save) trillions of dollars. https://www.ox.ac.uk/news/2022-09-14-decarbonising-energy-system-2050-could-save-trillions-oxford-study

Economics and traditional national security concerns now point in the same direction as environmental protection – there is no excuse for delaying further. The door is closing fast, but there is still a way out.

In the words of Ferris, tweets like this are so choice ?

RT @KHayhoe@twitter.com

When we see climate changing, we don't automatically jump on the human bandwagon, case closed. No, we rigorously examine and test all other reasons why climate could be changing: the sun, volcanoes, natural cycles, even something we don't know yet: could they be responsible? ..

How is science questioned? Through meticulous review to determine if there are any errors or missing factors that are not accounted for.

That is exactly what climate scientists have done for over a century, and that is why we KNOW climate change is real, human-caused & serious.

Here’s an example of how it is done. Not by casting ad hominems on Twitter that take two seconds to type, but through painstaking and detailed analyses that take months to complete and are then peer reviewed. https://twitter.com/khayhoe/status/1149134713648484352

Overnight, the world agreed to a "Paris Agreement" for biodiversity! It's the Kunming-Montreal Global Biodiversity Framework and its goals aren't expressed in degrees of warming but rather in land and water protected: 30% by 2030 globally.

Climate change is real, it’s human-caused, its impacts are serious … and there are solutions if we act now.

I am also experiencing the same.

I've never blocked so many climate denier bots (all no photo, first-name-plus-bunch-of-numbers accounts) as past 24 hours. There is an orchestrated effort underway right now to hijack the online climate discourse.

Stunning visuals show how wildlife is disappearing around the world, in the oceans and on land. Humans are taking over too much of the planet and climate change make survival harder.
