There has been a lot of discussion about negative emissions technologies (NETs) lately. While we need to be skeptical of assumed planetary-scale engineering and wary of moral hazard, we also need much greater RD&D funding to keep our options open. A quick thread: 1/10
Energy system models love NETs, particularly for very rapid mitigation scenarios like 1.5C (where the alternative is zero global emissions by 2040)! More problematically, they also like tons of NETs in 2C scenarios where NETs are less essential. https://t.co/M3ACyD4cv7 2/10
In model world the math is simple: very rapid mitigation is expensive today, particularly once you get outside the power sector, and technological advancement may make later NETs cheaper than near-term mitigation after a point. 3/10
This is, of course, problematic if the aim is to ensure that particular targets (such as well-below 2C) are met; betting that a "backstop" technology that does not exist today at any meaningful scale will save the day is a hell of a moral hazard. 4/10
Many models go completely overboard with CCS, seeing a future resurgence of coal and a large part of global primary energy occurring with carbon capture. For example, here is what the MESSAGE SSP2-1.9 scenario shows: 5/10

There is a lot of confusion about carbon budgets and how quickly emissions need to fall to zero to meet various warming targets. To cut through some of this morass, we can use some very simple emission pathways to explore what various targets would entail. 1/11 pic.twitter.com/Kriedtf0Ec

One of the best decisions I made during a very turbulent 2020 was to leave conventional coding behind and embrace the #nocode movement. @bubble made this a reality. Although my own journey thus far is premature, I’ve learned a lot so here’s a power thread on....
‘How I created @buildcamp sales funnel landing page in under 2hours’.

Power thread here 👇
1. Started with a vanilla bubble app ensuring that all styles and UI elements were removed. Created a new page called funnel and set the page size to 960px as this allows the page to render proportionately on both web and mobile when hitting responsive breakpoints.
2. Began dropping elements onto the page to ‘find the style’. These had to be closely aligned to our @buildcamp branding so included text, buttons and groups - nothing too heavy. Played around with a few fonts, colors and gradients and thus pinned down the following style guide.
3. Started to map out sections using groups as my ‘containers’ to hold the relevant information and imagery needed to pad out the sales pitch. At this point, they were merely blocks of color #ff6600 with reduced opacity set to 5% to ease page flair.
