Watch my interview on @SkyNews yesterday, talking about @ExtinctionR and #ClimateCatastrophe!

Just got home after 3 days protesting in London (PhD work awaits unfortunately). Spent most of that time with placard full of graphs explaining to public why I thought I must be there.
I carefully stood to side of the road so as not to be arrested, but over 300 protesters have been, and hundreds more waiting. Must say that from what I saw police were very agreeable and not overly forceful in removing protesters, let's hope it stays that way.
Although disruption to people's daily lives is not ideal, it's necessary to get this issue attention it deserves. One of the arrested was a Lawyer who negotiated 2015 Paris Climate Agreement (which has been largely ignored since) - shows this is the kind of action we now need.

We published a new paper in Energy Policy:

“Re-examining the role of nuclear fusion in a renewables-based energy mix”

We attempt to clarify what a realistic fusion reactor could, and could not, likely offer the world.

1/n
sciencedirect.com/science/articl…
We wrote this paper for:

a) Policy people / the public, who want to know what fusion is and isn’t,

b) The fusion community, as we together need to better understand the context and likely competitive landscape our work will face.

2/
Despite a recent surge in activity, the timeline for fusion development is slow. And even once demonstrated, the tech doesn't lend itself well to a rapid rollout.

Fusion can likely only be significant after the world is already renewables-dominated.

People are still tweeting about the NYT's piece on the SPARC nuclear #fusionenergy release, so as a fusion PhD student I'm going to explain what it is and isn't...

🧵

nytimes.com/2020/09/29/cli…
Commonwealth Fusion Systems is a spin-out from MIT Plasma Science and Fusion Centre. A few years ago they described an innovative design for a power plant called ARC, which proposed using recent advances in high-temperature superconducting (HTS) magnets to shrink the machine.
This works because the fusion plasma is held by the strong magnetic field, as each charged particle corkscrews tightly around the field lines.

The higher the field (denoted B), the tighter the corkscrew, effectively shrinking the whole plasma.

Regardless of your opinion on Carbon Offsets, companies will want to use them.

So activists pressuring companies need to understand the different types of offsets!

My friend @EliMLarson was part of a team that created a set of Offsetting Principles to help you understand.
As he (and the other academics at Oxford who worked on this) argues then only offsets with certain, very stringent conditions can be relied upon to reduce future warming.

Very few currently available offsets are geologically-permanent, for example.

But offsets which do meet those standards are plausible, and some companies will definitely try to buy lots of them.

(see @BCG 's recent net-zero pledge - a company rich enough to buy the real deal assuming they will buy A LOT of offsets)

My friend Leo Buizza (who is too smart to be on twitter) took a closer look at @BCG 's new net-zero emissions pledge.

Is it #greenwashing? Let's find out... 🧵

leosthreeminuteblog.home.blog/2020/09/04/so-…
For starters, credit to @BCG for making the pledge at all – it’s already more than @McKinsey and @BainAlerts have done (two of their main competitors), from what I can tell.
@BCG are talking about net-zero by 2030. That's not bad - well before the IPCC's 2050 date, and therefore in line with keeping to 1.5C of global warming.

But what about the fine print...

Proud to be in London today marching with @ScientistsX, alongside @XRlawyers.

#ActNow Image
The Climate and Ecological Emergency Bill is a piece of work to be proud of, whose championing shows that @XRebellionUK can continue making a difference.

It's also encouraging to see climate experts involved from the start in the creation of the bill.

We are in a climate crisis, but must not give in to doomism.

@GalenHall4, @ColleenBSchmid1 and I explain why environmental doomism is never the right philosophy.

opendemocracy.net/en/oureconomy/…

1/🧵
In particular we look at the most pernicious example of doomism within a movement @GalenHall4 and I are members of: the damaging effect of Jem Bendell’s @deepadaptation agenda on @ExtinctionR .

2/
The original Deep Adaptation paper has been downloaded 100’s of thousands of times, and Bendell contributed a chapter to the Extinction Rebellion handbook, and has spoken for the movement many other times.
