Experts: The key ‘unknowns’ of overshooting the 1.5C global-warming limit - Carbon Brief

On the sidelines of a conference, Carbon Brief asked a range of experts what they consider to be the key “unknowns” around overshoot.

Last week, @ceciliakeating.carbonbrief.org and I attended the first-ever conference on climate "overshoot" in Vienna.

Here's our summary of the wide-ranging discussions. (Bearing in mind we were two journalists covering 8 conference themes...!)

FACTCHECK: Claire Coutinho claims UK gas power only costs £55/MWh…

…but she is ignoring a few small details:

🤫 Gas prices always rise in winter
🤫 Gas plants cost money to build
🤫 CO2 causes economic damages

Yet more embarrassment for the Times, which has printed a ludicrous – and almost certainly false – line about windfarms being “dismantled” near Trump’s Scottish golf course

But why pick up the phone, as I did, when you can print nudge-nudge rumours instead?

Hi, just to confirm: there was no “deal”. We were just informed by Springer (back in 2016!) that we – along with about 200 other outlets – had been added to their “SharedIt” whitelist.

Really interesting guest post from @markengland.bsky.social unpacking why Arctic sea ice loss has slowed and how "climate models clearly show that such periods are expected parts of climate variability" ⬇️

Guest post: Why the recent slowdown in Arctic sea ice loss is only temporary - Carbon Brief

Observations reveal that Arctic sea ice extent at the end of summer has halved, since satellite records began in the late 1970s.

Yesterday's newspaper reported a major shift: "The OBR now thinks…net-zero will have a far more damaging impact on borrowing…"

In fact, the OBR had said the opposite!

Thanks. It did come up frequently throughout the conference, but there weren’t sessions dedicated to it (as far as I recall). We do touch on it a bit in the final section, but there was a lot to cover!

NASA scientists will apparently no longer be able to read @nature.com at their jobs, as the Trump administration has canceled all subscriptions to Springer Nature journals, per the agency. (1/3) 🧵

Max Kozlov @maxkozlov.bsky.social · Jun 30

Received one more - this time from NASA

“NASA sent a notification to Springer Nature stating the agency was cancelling its subscriptions. Our engineers and scientists will still have access to NASA mission data shared with their journals, as well as have access to many other scientific journals.”

And then @thetimes.com, revealing its credulity, has followed with its own piece that does exactly the same thing (just 2 hours later):

Wine prices up 9p a bottle thanks to net-zero ‘glass tax’

Under the ‘extended producer responsibility’, retailers and manufacturers have to pay fees for disposal of packaging they use

Here's more on the “Packaging extended producer responsibility” scheme: commonslibrary.parliament.uk/research-bri...

I suspect the Telegraph knows that the connection to net-zero is bogus as it only mentions the phrase in its headline & opening line.

Net zero tax to push up price of wine

Standard bottle will cost 9p more and 330ml beer bottle will rise by 4p under levy meant to encourage environmentally friendly packaging

More net-zero misinformation in the Daily Telegraph.

It claims that a proposed scheme to put the cost of recycling onto packaging producers, rather than local councils, is a “net-zero glass tax”.

It is about waste management, not net-zero.

Somehow, this made it onto the frontpage 🤦

New guest post on how 60% of the CO2 being released from the world's river rivers is coming from "ancient" sources, which were long thought to be stable.

It is a "warning sign that human activities, especially climate change, could intensify the release of carbon to the atmosphere via rivers".
