Renewable energy is as big a threat to biodiversity as oil and gas activities.

Is Climate Change the Biggest Threat to Biodiversity?

As we can see from the chart above, climate change, as a whole, was down in 7th place in the list of biodiversity threats. The chart is from 2016 but there is no reason to believe that climate chan…

What does "Net emissions" mean? Are these consumption-based emissions and do they include LULCF emissions, air transport and sea freight emissions?

Yes, civilisation is what most people want to save, including self-styled environmentalists. mikerobertsblog.wordpress.com/2025/06/26/p...

Sustainable ... growth?!! Can you hear yourself?

Mike Roberts @nzmike.bsky.social · 3d

All governments are in climate denial. They all prioritise economic growth over climate, or the environment.

Sounds like you need a Zoom meeting to figure out when you should have a Zoom meeting.

Not needed if you stay away from sugar. Flouride is not totally safe as it can destroy good mouth bacteria.

Mike Roberts @nzmike.bsky.social · 8d

Another safe way is to not imbibe sugary drinks or eat food with added sugar.

if that's our best weapon, there really is no hope.

Would we notice any difference?

Mike Roberts @nzmike.bsky.social · 15d

Well, the modernity experiment has a finite future anyway.

Mike Roberts @nzmike.bsky.social · 17d

That's good but note that EVs are not clean.

You don't need to wait.

She kind of implies that humans have a distinct nature compared with other species. That is human exceptionalism. But at least she realises that there is no way out.

The only clean energy is foraged food. I doubt that's what you're referring to.

The 1.5°C target is dead. There is no way to achieve that, without collapsing society.

Mike Roberts @nzmike.bsky.social · 25d

But what exactly is the accumulated number each year? Is each month's anomaly just added to the next month's number? If so, what is it telling us?

Mike Roberts @nzmike.bsky.social · 26d

What does this mean?

Mike Roberts @nzmike.bsky.social · 27d

I'll take the under also. Extent is not the best measure of sea ice health. Even area doesn't tell us the whole story, and that was the 4th lowest area, this year (10th lowest in extent). Volume would be the best measure but we don't measure that directly. But August was the 3rd lowest PIOMAS volume

Of course it's not. If the path is two centuries long, it gives us time to adapt. I'm not saying we will but a very long path is different from a very short one.

Mike Roberts @nzmike.bsky.social · 29d

What is ridiculous about it? The future hasn't happened yet. That's a simple, though true, statement and we MAY know the most likely outcomes, but definitely not the path to those outcomes.

Mike Roberts @nzmike.bsky.social · 29d

Now is the present. No-one knows the future.

It's amazing how many people think renewable energy harvesting infrastructure is clean. It's as though they think that all our environmental problems will disappear if the transition can be completed.

Yet more evidence from @ember-energy.org that the global roll out of 'electrotech' is accelerating fast and will push fossil fuel demand into structural decline very soon. www.businessgreen.com/news/4519025...

Study: 'Electrotech' growth to push fossil fuel demand into terminal decline by 2030

Impact of clean energy and transport technologies on fossil fuel demand set to be far higher than initially predicted, think tank claims

Seems like it but no-one can see the future, in detail.

Facts don't form beliefs, the make up of one's brain does. Hausfather can do nothing about the way his brain works, because "he" is his brain.

I thought that was already in progress.
