Yes. An incredibly bad own goal.

Many thanks! Please do add me as I'd like to contribute to the conversation.

Glad to help. It’s the rate of change of growth that is down. That is slowing growth, which will lead to decreased fossil fuel use and decreased emissions. Notice that other oil uses were in decline and oil use for fossil fuels in land transportation is no longer growing.

Global emissions are still increasing. However, reducing the rate of demand growth will eventually lead to reductions in fossil fuel consumption & falling emissions. This is the 1st step. And emissions in China, the biggest emitter, fell for first time. www.carbonbrief.org/analysis-cle...

Yes. It’s the first step and we are making progress globally.

Yes, decline is coming. If you look carefully at the plot, you’ll see that there is no demand growth in transportation left in the plot. The only two sectors that showed demand growth in 2024 were aviation and feed stocks, ie plastic, petrochemicals.

You can take that perspective. But that the exponential growth in renewables is slowing demand significantly over nearly half a decade and across global sectors is an important development. You can’t encourage folks with pessimism. 🧪🔌💡☀️💨🔋

Decrease growth in demand for nearly have a decade is good new.

We built up fossil fuel infrastructure since the Industrial Revolution. This is multiple years of data -nearly half a decade- showing a decline in growth. If the trend continues in this direction, you will in fact decline fossil fuel use.

Key IEA figure shows demand growth for oil has declined from ~5.25 mb/d in 2021 to ~0.8 mb/d in 2024. 🧪💡🔌☀️💨🔋 #FossilFuelsAreStrandedAssets

The company makes two versions of this craft. One is VTOL. I suspect they used common body types to save on design and build costs.

And: “With sadness, I am informing you that Landsat 7 has performed its last maneuver and depleted all of its useable fuel. For all planning purposes, Landsat 7 has now become a non-maneuverable satellite,” said Joe Blahovec, USGS Chief of the Satellite & Ground Systems Operations Branch at EROS. 🧪

U.S. satellites are descoped in such a way that they generally come down somewhere over the Deep South Pacific, far from land at a location know as Piont Nemo. It is considered the furthest place from land on earth. 🧪 en.wikipedia.org/wiki/Spacecr...

Unshielded electronics are susceptible to EMPs. This is true of internal combustion aircraft too. However, they can be hardened against EMPs using a faraday cage. Technology dating back to 1836. en.wikipedia.org/wiki/Faraday....

Here's a map of the existing ALIA EV charging network. Their website identifies 150 airfields with chargers across the midwest, SE, Mid-Atlantic and New England states. That a goods start for regional air transport. 🧪🔌💡.

You think we can't build out eletrical infrastructure? How many EV chargers were there 5 years ago? 🧪🔌💡https://afdc.energy.gov/fuels/electricity-locations#/find/nearest?fuel=ELEC

This is necessary they explained, due to the deep staff & funding cut that the National Academies has experienced due to changes in administration priorities. 🧪

Fortunately, Landsat 8 and 9 continue the mission with the most advanced Landsat sensors to date. 🧪🛰️ landsat.gsfc.nasa.gov/satellites/l...

It completed its work dutifully as the second longest Landsat mission, surpassed only by Landsat 5's 29 year long operational mission. 🧪🛰️ www.usgs.gov/landsat-miss....

This is great! I think you should add the storage scale factor to the plots and routinely show the change in scale factor. It provides a useful metric of progress! 🧪🔌💡

Sadly. And the FEMA Director just admitted that they did not know that the US had a hurricane season. 🧪 www.reuters.com/world/us/fem...

As more renewables are brought onto the grid, the scaling factors are decreasing, particularly for rooftop PV. The difference between wind, rooftop PV and utility PV reflects the trends in deployment of those technologies. PV is building out much faster than wind.

But if we don't fund climate science we will be less prepared to understand why those changes are happening or what we can do to mitigate and adapt to them. The demolition of US science is not in our best national or the global interest. 🧪
comment in response to

A large part of the reason that we know that the climate change we are now experiencing is anthropogenic or human caused is due to work conducted by the prior paleoclimate program (NSF-P2C2) & (NSF-P4CLIMATE).
Devastating climate impacts will continue whether we fund valid science or not. 🧪
comment in response to
post
It’s always amazing to see how these results continue to improve with decreasing scaling factors. What is the scaling factor for the storage? Can you plot the change in scaling factor again to show the trend?

I'd like to get an auxiliary cold climate heat pump that can supplement my three season heat pump for the 1-2 weeks per year when temps can get to -15°F.
comment in response to

This seems like a good solution if you have a hydronic or radiant heat system. Many systems in the US are forced air with either ducted or ductless HVAC.

Bummer. I should have read the fine print.
