I had a great time talking about climate change - and how we can reduce our emissions and build resilience to prevent suffering - at @Climate2020AZ today. Here's what the audience of over 350 students, academics, govt, nonprofit, and community members had to say and ask ...
@Climate2020AZ What does climate change in Arizona look like to you? @Climate2020AZ
@Climate2020AZ Who would you like to have a conversation with about climate change that went well? (watch my TED talk to find out how!) ted.com/talks/katharin…
@Climate2020AZ Lots of really good questions, many of which are answered by our Global Weirding episodes, like...
How do we deal w disinformation?
Is it too late?
@Climate2020AZ More good questions, like ...
Where do I find information on sol'ns? drawdown.org
What books would you recommend? amazon.com/ideas/amzn1.ac…

Infrastructure--buildings, transportation, energy, even communications--is critically vulnerable to climate impacts AND key to climate mitigation too. So this is a great move. @cathmckenna knows climate and understands why it's key to factor it into all our big-budget decisions.
@cathmckenna In the U.S., the American Society of Civil Engineers gave most infrastructure a D+ and estimated it would take $4.5T by 2025 just to bring it up to par ... not even considering the need to increase our resilience in the face of a changing climate. infrastructurereportcard.org
@cathmckenna Globally, @OxfordEconomics estimates $94T is needed by 2040 to provide a "well-functioning, modern infrastructure is central to economic development and to quality of life." oxfordeconomics.com/recent-release…

A favourite line of those who want to continue our dependence on fossil fuels as long as possible is, "those climate models, you just can't trust them." Yet these are the energy models they trust for renewable energy forecasts?! (h/t @aukehoekstra + @GarethSJones1 for figures)
@AukeHoekstra @GarethSJones1 When you look at how well the rudimentary climate models + back-of-the-envelope scenarios of the 1970s and 1980s have performed relative to observations, it's even more stunning. Read: carbonbrief.org/analysis-how-w…
@AukeHoekstra @GarethSJones1 And climate models are constantly having their tires kicked in all kinds of ways, as this Global Weirding episode explains:

THREAD: In a new study in @nature we present a way to avoid the bias that burdens future generations and the risky strategies that current #climate change mitigation pathways suffer from.

A #climatetwitter explainer

#Fridays4Future #ClimateStrike #ParisAgreement

(1/n)
Existing #ClimateChange scenarios focus on reaching a target in 2100

but by doing so weirdly suggest that the best way to achieve a #climate target is to delay action first, miss it over the next decades, and then to try to make up for it later

(2/n)
This puts put a disproportionate burden on future generations, who:
-will suffer higher #climate impacts in their lives
-are burdened with later cleaning up the mess by actively pulling #CO2 out of the air

This strategy is very risky and can be avoided

Amazing footage - apropos this and the Watson River flood of 2012, my colleagues and I were inspired to write a paper looking at the potential for high runoff events in the future in this paper researchgate.net/publication/32…
In our future #climate simulations the region in western #Greenland that includes #Kangerlussuaq from the #icesheet to the shores of the #DavisStrait we show how melt + runoff of early 2000s was outpacing mid-century projections*

*Caveat: only one GCM #ECEARTH shown here
The more extreme the scenario - the more extreme the projected melting, but note the very high interannual variability.

Biggest cheer during @iowademocrats chair @troymprice's opening remarks came after he predicted #Iowa Ds will "send @joniernst into an early retirement." #IASen #HallofFame
Sen @CoryBooker is 1st candidate to speak at #HallofFame event. (19 candidates will each have 5 minutes)
"We are being tested. This is a moral moment in America, and we must meet this test. I'm running for president because we can't take 4 more years of Donald Trump." #iacaucus
But @CoryBooker isn't just running to beat Donald Trump. That's the floor, not the ceiling. We can't just run on what we are against. Democrats need to tell people what we are for. "Every American needs health care, and make no mistake, abortion is health care." #iacaucus

1. Thread:

Riots in France, 2nd rejection of carbon tax in Washington State, and u-turns in Germany and Ireland, all since Oct:

Are carbon taxes are dead, and we should look to plan B on climate?

Short thread.
1. I didn't realize how badly Trump has eviscerated access to federal #climate data, so I went and looked at the USGS site.
2. In December, there were 5,932 climate science items linked there (9 were just pictures). Today there are 416 and 292 are just pictures.
3. In December 2016, 320 of those items were links to #climate data. Today, 0 links to data. 5,271 were web links. Now, 0 web links.
