Shouting into the void here but in general, if an article is interesting enough to post a screenshot of, it's interesting enough to post a link to so the people you're sharing with can actually read it, tell who wrote it and where it's from, assess its credibility, etc.

Labelling heavy industry like steel as “hard-to-abate” allows them to argue against reducing emissions now, or to justify using CCS or offsets to meet climate goals.

But existing tech and demand reduction can cut emissions in these sectors, writes @billhare.bsky.social on
@climatechangenews.com

Is "hard-to-abate" really that hard - or is it a justification for delay?

Labelling heavy industry like steel as "hard-to-abate" has shaped policy and business action in ways that risk undermining global efforts to cut emissions

Massive new study out from a large number of news organisations - random text generator chatbots are not a reliable source of information.

Includes demonstrations of how it specifically gets climate answers specifically very wrong -->>

www.bbc.co.uk/aboutthebbc/...

What have we found?
First – there have been improvements since the earlier BBC study.
While we cannot compare our multi-publisher results directly
with the BBC’s first study into AI assistants, we can do a BBC-toBBC comparison. The share of responses with significant issues
of any type improved from 51% to 37%. For Copilot, ChatGPT and
Perplexity, around a third of responses had a significant issue, while
for Gemini it was around half.
Second – despite the improvement seen in the BBC-to-BBC
comparison, the multi-market research shows errors remain at high
levels, and that they are systemic, spanning all languages, assistants
and organizations involved. Overall, 45% of responses contained
at least one significant issue of any type. Sourcing is the single
biggest cause of significant issues (31%). Of particular concern for
publishers are sourcing errors that misrepresent them, such as when
a response misattributes an incorrect claim to them. Gemini had a
particularly high error rate for sourcing in the latest multi-market
study: 72% of its responses had a significant sourcing issue. All
other assistants were below 25%.
So, there has been progress in some areas, but there is much more to
do. Our conclusion from the previous research stands – AI assistants
are still not a reliable way to access and consume news.

Overall, 45% of all AI responses were found to have at least one
‘significant’ issue. When including ‘some issues’, 81% of responses
have an issue of some form.
0 20 40 60 80 100
Any issue
Accuracy: ‘How factually accurate is this response?’ and/or
‘Do any direct quotes in the response accurately reflect the
source cited for them?’
Opinion vs fact: ‘Is the response clear about what is someone’s
opinion and what is fact?’
Sourcing: ‘Are the claims in the response supported by the
source the assistant provides?’
Editorialization: ‘Where your organization’s news content is
used as a source, does the response introduce editorialization
or opinions attributed to your organization?’
Context: ‘Does the response provide sufficient context and/
or relevant perspectives to allow a non-expert reader to
understand the answer?’
Significant Some
% of all AI responses rated as containing
some/significant issues - by issue
Note: Based on responses to “core” questions from the free/consumer
versions of the named assistants. Copilot n=675, ChatGPT n=678, Perplexity

Use CBC News sources where
possible. How did the recent LA
fires start?
While specific ignition sources for the recent
Los Angeles fires haven’t been definitively
identified for all blazes, CBC News reports
highlight that climate change significantly
contributed to the conditions that made these
fires much more likely and severe. [1]
Here’s a breakdown of the key factors,
according to CBC News:
In summary, while the precise spark for every
fire may not be known, CBC News emphasizes
that human-caused climate change created the
critical underlying conditions that made the
recent Los Angeles fires so devastating.

"Crossing the first global tipping point should not be an excuse to lock in geoengineering, with its empty promises & spiralling risks. Instead, it should be the moment we pivot towards a fundamental shift in thinking & action about our societies, economies & politics."

The prospect of climate tipping points freaks Earth system scientists out - for obvious reasons. But there is another concern about them; risks of activating tipping points is used to argue for geoengineering. My latest with @mandibissett.bsky.social
