I joined @katydaigle and @iron_emu on @Reuters yesterday to talk all things climate. We received so many questions we weren't able to get through them all so I wanted to answer a few more here. Here we go! pscp.tv/w/1gqxvagqNBjJB
First, if you'd prefer to watch our chat on YouTube, here is the link: and while you're there, don't forget to subscribe to Global Weirding too! globalweirdingseries.com
Q. What's the most serious thing standing in the way of genuinely effective action on climate?
A. Our “threat-meter” is upside-down. We see sol'ns as posing an imminent risk but impacts as distant/far off. There are many ways to help flip this. Here's one: ted.com/talks/katharin…
Q. Which sovereign governments are performing best and worst regarding the Paris Agreement?
A. This is what @climateactiontr tracks, and here’s where we currently stand. Note the US and Russia: both gray, while China is red. For more, see: climateactiontracker.org/countries/ ImageImage
Q. Is voting more impt right now than a single person's individual reductions?
A. Action at all levels is key - and talking about what we are doing, equally so! But if you live in the US I'd agree voting is the single most impactful climate action you can take this fall.
Q. What do you think of the report of recycling being taken to the dump?
A. Where I live, they already did that yrs ago so I know how it feels: frustrating + discouraging! This shows why system-wide change is SO impt. We can do our best but w/o it, the deck's stacked against us.
Q. How well, or how poorly, is the media handling these problems?
A. According to @YaleClimateComm, people don’t hear much about climate in the media, but they want to! I'd add though: we need stories on local impacts + viable sol'ns, not more doomsday clickbait headlines. ImageImage
Q. Which demographics are most and least interested in climate change?
A. The main predictor of US climate opinions is POLITICS. The more conservative, the more likely to reject. By demographic, tho, Hispanic/Latino are most concerned + conservative white are least concerned. ImageImage
Q. In your experience is it a good idea to connect Covid to climate change, or is that a bridge too far?
A. Climate change is the great threat multiplier, exposing the weaknesses in our society and amplifying them. So no, I don’t think it’s too far. Watch:
Q. If we magically stop emissions today, how long would it take for the climate to stabilise?
A. Atmospheric CO2 levels will stabilise when humans are taking up as much CO2 as they produce (when the bathtub drain=the tap), but it will take climate thousands of years to rebalance. Image
I've also gotten a lot of questions lately about how long CO2 lasts in the atmosphere. Here is an explainer from a Nat'l Academy report I co-authored a few years ago called "Climate Stabilization Targets" (good reading if you want to learn more!) nap.edu/catalog/12877/… Image
Finally, a thread I wrote earlier that explains the Paris targets
And to end, the thread (or my chat with @neiltyson if you prefer video!) that explains how our coronavirus response affected carbon emissions and climate and why that is both discouraging AND hopeful.
I answered many other questions in the video but if you'd rather read a synopsis, @lauriegoering has it covered! news.trust.org/item/202009251…

The science carnage of the Trump administration continues, unchecked by the recent election.

It amazes and saddens me how many people are willing to let some of the richest multinationals in the world off the hook when it comes to carbon emissions and blame themselves + other individuals instead. "We're the consumers" say the drug addicts, "so it must be our fault." Image
Guilt can be a powerful motivator of societal change, yes ... when those who feel that guilt have the power to effect change at the scale that would mitigate that guilt. When it comes to carbon emissions, tho, the fact is that we as individuals DON'T.
That is why, as @MichaelEMann explains so clearly and lucidly here, we need system-wide change. time.com/5669071/lifest…

Royal Dutch Shell is #6 on the list of 90 companies responsible for 2/3 of greenhouse gas emissions since the dawn of the industrial era. Their cumulative emissions equal those of the country of 🇨🇦. sciencemag.org/news/2016/08/j…
Yes, everyone must do their part - starting with the biggest emitters. That means you, @Shell.
Despite what the CEO of Shell claimed in 2019, eating food that's in season, avoiding fast fashion and recycling ISN'T GOING TO CUT IT when it comes to stabilizing climate change. Those actions will make no more than the tiniest of dents. vice.com/en/article/a3x…

Press release from the White House Office of Science and Technology Policy claims science + tech highlights of Trump's first term include "ending the covid-19 pandemic" and "taking action to understand and protect the environment." politico.com/news/2020/10/2…
The truth? The Trump administration has or is in the process of rolling back over 100 pieces of legislation that protect the "clean air, clean water, and resilient environment" the press release claims to have protected. Source: statista.com/chart/18268/en…
The Trump administration also deliberately misrepresented the findings of the National Climate Assessment and just this fall hired new appointees who explicitly reject the science to "consult" on the NCA process in the future.

US DOE has blocked reports for more than 40 clean energy studies. “There are dozens of reports that can’t be published,” said Stephen Capanna, former director of strategic analysis who quit in frustration in April 2019. h/t @dan_kammen cc @SolomonG_R invw.org/2020/10/26/tru…
.. while claiming that energy efficiency - a powerhouse win-win solution which could reduce US carbon emissions a whopping 50% and save $700B - is all about making people's windows tiny (?!) aceee.org/sites/default/…
... and that wind energy, which supplies 20% of Texas' electricity, is a bird killer. Well sure...but compared to fossil fuels, windows, and cats? It's quite literally microscopic; plus there's lots of cool new tech to reduce wind bird deaths further. sciencedirect.com/science/articl…

Mrs. Eunice Newton Foote (1819-1888) was a women's rights advocate & pioneering scientist. In 2020, @EarthSci_Info + @Roland_Jackson reanalyzed the data from her groundbreaking 1856 study to show you could estimate a climate sensitivity of 2-3C from it! royalsocietypublishing.org/doi/10.1098/rs…
Climate sensitivity is the equilibrium change in global mean temperature resulting from a doubling of CO2 relative to pre-industrial levels. It's usually represented as a probability distribution with a mean value around 2.4-4.7. Here is a recent review: agupubs.onlinelibrary.wiley.com/doi/pdfdirect/…
Why don't we know the value for sure? Because we've never seen this much carbon going into the atmosphere this fast with these precise initial conditions. We are conducting a truly unprecedented experiment with our planet. iopscience.iop.org/article/10.108…
