The Seventh Carbon Budget
The Climate Change Committee (CCC) has published its Seventh Carbon Budget (CB7), a set of recommendations to UK Government on GHG emissions for the years 2038-2042. The target is to achieve an 87% reduction in emissions by 2040, setting the budget for 2038-2042 at 535 MtCO2e. CB7 is a big document, but the Climate Evidence Unit (CEU) of the University of Leeds has provided a useful review. 2040 is of course 15 years away (or to put it in terms that politicians understand, three general elections away). You can download the CEU's review as a 19-page PDF. In this format it would I think prove useful source material for a group discussion.
There is a summary of the review in The Conversation.

Less
I had a good discussion with my Environmental Sustainability group last week around the book ‘Less’ by Patrick Grant of The Great British Sewing Bee fame. I read the book first, came prepared with some highlights and interesting facts and others chipped with thoughts and examples of items that have lasted years, things that fell apart quickly, where we can get clothing repairs locally, repairing techniques and overcoming mental barriers to shopping secondhand. The book is well worth a read and the theme of buying less, buying better and buying local seemed to chime.

Rewiring Britain
I like Justin Rowlatt's climate reporting for the BBC, so I recommend his 'Rewiring Britain' piece for Panorama. It's 29 mins and I think it would be a great discussion topic for a climate group. If objectors to solar farms and transmission lines get their way then decarbonisation of the UK electricity system isn't going to happen. Do we own the view from our bedroom window?

Alongside Rowlatt's report your group could look at the Clean Power 2030 (CP30) plan from NESO: "advice [to government] on achieving clean power for Great Britain by 2030". You can find more on this in Second Nature 026. CP30 requires that GB must contract as much offshore wind capacity in the coming one to two years as on the previous six years combined, and that we build new transmission lines on time - twice as much in the next five years as was built in total over the last decade. This requires 1,000 km of network onshore and over 4,500 km of offshore.
Solar or food production?
Here's a balanced article on the 'Land for Solar or Food' controversy. Very useful for a group discussion. Take a vote before and then after!

Nuclear Power
See Second Nature 013 for a braindump on this. There is follow-up comment in SN014 and SN015, or google for press coverage of Sizewell C.
Carbon Capture and Storage
CCS features in the UK's plans for net zero. George Monbiot argues against government policy, saying that it will increase UK emissions rather than reducing them. Prof Myles Allen has a different view. Read both of them and decide if you are for or against.
Energy from Waste
See Second Nature 014 for a briefing on this. Are you for or against?
Zero Carbon Britain
Zero Carbon Britain is a description of what the country might look like if we achieve zero emissions (zero rather than net zero I think: there is no CCS in here). The document is available online and is summarised in Second Nature 017. It implies significant changes to the lifestyle of the average Brit. Would we vote for something like this?
Being hated worked for Just Stop Oil
So argues George Ferns in The Conversation. "Disruptive protests may be unpopular, but they are effective at attracting media attention and public awareness". A great topic for groups to discuss I think.
Don't Talk About Climate
In The Guardian Sarah Stein Lubrano argues that our understanding of how political persuasion (and, by extension, climate persuasion) works is wrong: debating and providing information has little effect on people's beliefs. It is our friends that have the power to change our beliefs and behaviour - not by arguing with us, but by being around and showing us new ways of living. People are most likely to engage in climate-
friendly action if their friends do - far more likely than if they are given cash incentives. That has obvious implications for what we do.
