Ich kann nicht verstehen, warum @rahmstorf so etwas schreibt: hätten wir diese Menge an Energie zur Verfügung, wäre die Klimakrise gelöst. . Eine kurze Analyse 1/n
Was könnten wir tun, hätten wir 170 TW an konstanter Leistung zur Verfügung? Wir könnten zb. 10 Milliarden Menschen auf den Primärenergiekonsum der USA anheben. Da wären wir bei 84 TW. 2/n
Dann hätten wir noch 86 TW zur Verfügung. Das entspricht 753 TWh im Jahr. Mit dieser Energiemenge könnten wir in 7,5 Jahren die kumulativen Emissionen der Menschheit bis zum Jahr 2022, aus der Luft holen und damit die Temperatur um über 1° C senken. iea.org/data-and-stati… 3/n
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?
Pakistan floods are terrible. Question for those on #Climatetwitter #energytwitter, has reporting you have read discussed Pakistan's dollar debt crisis and IMF loans?

Climate crisis & Debt crisis are two sides of the same coin. Many developing countries face a lost decade just as Climate crisis worsens. They can't invest in green if they are broke & paying high interest rates. Thread prospect.org/world/developi…
IMF board met today & acc to Pakistani officials, revived stalled loan program approved in July 2019 to disburse $1.17 billion to reduce burdens of the economic-ecological crisis. Will IMF impose conditions of removing subsidies?hrw.org/news/2022/08/2…

Quiet climate policy lives.
The supposition is that the IRA is the Green New Deal by another name and that it is this sweeping, transformative legislation but look away from #ClimateTwitter for a second and you'll be compelled to agree how quiet it is.
To be clear, this is a feature, not a bug, of a quiet, investment- and technology-focused approach to climate policy.
Look how much can get done by, ahem, saying the quiet part out loud!

Heat pumps are an essential climate solution. But there's very little data on how much they actually cost.
To fill some of the gap, we surveyed homeowners and analyzed publicly available data.
Here's what we learned:

First, I should start with the problem that motivated this research:
Most data on the cost of heat pumps is widely inaccurate.
If you look up how much a heat pump costs on Google, you'll probably land on a page from This Old House, Angi, or HomeAdvisor.

They begin by delaying a decision on HCAP, the $9000MWh price cap until they've decided on ORDC (Operating Reserve Demand Curve) as the two are related. Their analysis of ORDC change impacts is not ready so they will hold off on any decisions on either.
I’m writing a #CartoonClimate 2nd ed, and the draft has our best guess for BAU as SSP3-7.0. Here’s my case, but I invite #ClimateTwitter and #EnergyTwitter to disagree! @hausfath @ramez @DrKateMarvel @AdrianRaftery1 @RogerPielkeJr @KHayhoe @JosephMajkut @RobertStavins [Thread]
2/ Context: The draft mentions the possibility of a low-emissions future (“electrify everything”) and a high-emissions future (fossil-fueled catch-up) and specifies key issues—economic growth, technology, policy—before laying out our best guess for a no-more-policy BAU.
3/ A good part of my case comes from this chart from EIA’s IEO 1994, modified to include 2010 actuals. One modification was to move the legend because China 2010 was almost off the chart! (Note that this shows C; multiply by 3.67 to get CO2.) Take-off growth is unpredictable.
#ClimateTwitter Direct Air Capture (DAC)
In 2011, Rob Socolow estimated that 1MtCO₂/yr DAC would require a contact structure with height 10m & length of 5km.
Is that still the case?

If I look at these pictures of Climeworks Orca via @EdgarHertwich
The height is ~3m, the length ~10m, & 4 units
Area: 120m² for 4000tCO₂/yr
Or: 30,000m² for 1MtCO₂/yr (120/4*1000)
If 10m high (Socolow), then contact structure ~3km long.

This is rather crude, but is quite similar to the original Socolow estimate. If true, this is fascinating…
If contact structure is 10m high, then 1MtCO₂/yr requires 3-5km structure
1GtCO₂/yr requires 3-5000km
5GtCO₂/yr requires 15-25,000km

In sum:
1) Significant climate change impacts on food systems are already happening, & the risk of multi-breadbasket failures is increasing,
2) We will need to adapt, but
3) There are limits to adaptation - we urgently, urgently need to cut GHG emissions & draw down CO2.

This influence emerges in many ways.
Broadcast network execs are, I believe, insinuating to their production and reporting teams that it's "political" or "biased" to cover the #ClimateCrisis precisely becuz they don't want to alienate their oil and gas advertisers.

#ClimateTwitter we need to talk about percentages and denominators.
Depending on what you divide it by, any measure bringing about carbon emission reductions can be made to look ridiculously small, or huge.

For illustrative purposes, let's take this measure I've been tweeting about lately: introducing a generalised 130km/h motorway speed limit in Germany (where there isn't any) would cut annual emissions by 1.9MTCO2e.
Is it much? Is it little?
Is it much? Is it little?
So I get people in my mentions dividing that by the *total amount of global emissions in any sector, in any country*

As US convenes a Climate Summit, are developing regions a distraction from where the real action should be: emissions from HI emitters?
LDCs should focus on 1) electrification, regardless of fuel 2) slowing C growth & peaking lower 3) avoiding lock-ins.

The real problem isn’t rising emissions from the poor, it’s lack of reductions from high-emitters (mostly the rich).
It’s worse than the graph shows. The High Emitters’ *share* is falling, but absolute emissions are still rising (0.79% annually till '19).

Developed countries: “Why should we do anything when developing regions will emit more than us?”
This is FALSE.
Increase from HI emitters over last 15 yrs > increase from LO emitters.
Conveniently also ignores per capita or past emissions.

Of 21 indicators assessed for #ParisAgreement:
