Can you hear me?
We can see you!
thanks for hosting !!
Calling in from Seattle. Microphone inoperative for me.
Other: I always try to attend on Tuesdays when I can
Cool, I am in DC too, well, Arlington, VA
Thank you all for joining us tonight! Feel free to share your own questions for Steven and Dana here in the chat.
And if you have additional links recommendations to any of the other questions covered feel free to post here as well :)
Is there any history of reduced emissions rebounding even HIGHER once we hit a dip? I am wondering if we can at least feel good about this, or if it won't end up helping at all?
Good piece from NY Times on Covid-19 and carbon emissions: https://www.nytimes.com/2020/02/26/climate/nyt-climate-newsletter-coronavirus.html

thanks Brett. I asked that question in order to get some details for an op ed I have in mind. Steve’s bits were helpful, thanks.
Wonderful - thanks so much for asking it on Twitter and joining us Chris - share your op-ed when you have it written!
ha, will do if it amounts to anything!
With this one -could you both clarify Fat Tails and assessing the likelihood of any of these tipping points actually happening?
What about Palm Trees?
We need to plant trees with white leaves!
If you'd like to see Dana and Steve on full screen, you can use the speaker view button in the upper right corner of your screen
Then you can toggle back to Gallery View if /when you'd like.
A reverse of the aerosol and cooling question: Are there any short term emissions that increase heat that can be targeted?
We have about 100 M Acres of dead White Spruce in South Central Alaska. I’m burning some of them in our wood stove right now. What is the balance between harvesting recently killed trees then burning them for heat vs letting the trees fall & release CO2 as they rot?
Are there better sources to burn then than trees?
After Tamara’s question we’re all caught up in the chat - feel free to pose any remaining questions you have here and we’ll go to the phones.
I've read that the replacement for Freon that damaged the ozone layer has turned out to be a green house gas that is perhaps a hundreds of times worse than CO2. Now they are phasing those "f gases" out, what is the good alternative? Air conditioning is an important part of society in a hotter world, especially for the elderly.
On Wood Stoves: https://phys.org/news/2018-04-wood-stove-affects-climate.html
When we want to stop using gas furnaces for heating in winter an alternative is heat pumps which run on electricity and the use of refrigerants. I wonder if the hydroflourocarbons which are used are worse as they can escape.
There was a big hold up on Murkowski’s energy bill in the Senate on trying to force a phase out of f-gasses. Though the amendment had bipartisan support, it may have stopped that bill in the Senate.
Tom- this is a helpful and I believe a reputable way of visualizing this information: https://www.informationisbeautiful.net/visualizations/how-many-gigatons-of-co2/

thank you soo much
Thank you everyone!
I second that, thanks a lot
Thanks a lot!
