There should be a #ClimateTwitter #EnergyTwitter FAQ.
1. Where does the concept of "carbon footprint" come from?
2. Is it true that if we remove 2 GtCO₂ from the atmosphere, the ocean and land will outgas and equilibrate with the new atmosphere so that we will only achieve a reduction of 1 GtCO₂?
3. Is individual climate action important?
4. If the difference between 180 and 280 ppm CO₂ was the difference between an ice age and a temperate climate, why does an increase of another 150 ppm CO₂ lead to "only" ~3°C of warming?
5. What should we call the purposeful addition of alkalinity to the ocean for atmospheric CO₂ removal?
6. What does the latest IPCC report say about atmospheric CO₂ removal (CDR)?
7. Which ebike should I get?
8. How should we think about the nexus between electric vehicles, car dependency, and better cities?
9. Why should we contemplate atmospheric CO₂ removal (CDR) when we can just decrease the amount of solar radiation reaching the Earth's surface (solar radiation management; SRM)?
10. How can we reduce cars in cities?
11. How much global warming is caused by CH₄ vs. after it has oxidized to CO₂?
12. How can I learn about climate change and colonialism?
13. Where can I find a list of known atmospheric CO₂ removal (CDR) purchases?
14. Does having more rainy days and more extreme daily rainfall events harm the economy?
15. How do life cycle greenhouse gas emissions from a battery electric vehicle compared to that of an internal combustion engine vehicle?
16. Why does food waste have such a large climate impact?
17. Should I use the term “climate emergency,” “climate crisis,” or “climate change”?
18. What percent of fossil fuel CO₂ emissions have occurred in my lifetime?
19. How confident are we about future global warming projections?
20. Is precipitating calcium carbonate in seawater a good climate solution?
21. Are climate disinformation and greenwashing the same things?
22. Where can I find information about current US legislation relevant to technologies and practices that remove and store carbon?
23. What's so great about heat pumps as a climate solution?
24. How long would it take for nature to remove all fossil fuel CO₂ from the atmosphere?
25. Why does direct air capture (DAC) to removal atmospheric CO₂ take so much energy?
26. How were the land and ocean CO₂ sinks different before we started burning fossil fuels?
27. How has atmospheric CO₂ changed in the last 800,000 years?
28. What is wet bulb temperature?
29. How much more global warming will we have once we reach net zero CO₂ emissions?
30. Is RCP8.5 dead?
31. If we double atmospheric CO₂ from 280 ppm, how much are we likely to warm the planet?
32. What's more important for climate, food miles or choice of diet?
33. How do I tweet CO₂, CH₄, N₂O, etc.?
34. Do changes in the ocean and Amazon forest affect how much oxygen there is available for us to breath?
35. What's this I hear about human rights abuses associated with polysilicon production for solar panels?
36. What's new with solar energy?
37. What are some good films about climate change? Disclaimer: A few questionable choices here.

Fantastic thread. I'm sending everybody here in the future. Other unintuitive topics that could be covered perhaps: Tree planting & CO2 drawdown isn't as straight forward as it sounds. Also albedo effects of planting trees in northern latitudes may more than undo the neg CO2 iirc
