Okay sharing one more loop, this one from @cyclonicwx.bsky.social zoomed in visible 1-min meso over Category 5 #Hurricane #Erin.

Thanks to the 500 meter resolution of GOES-19 channel 2, you can still see features like the stadium effect & mesovortices rotating around the tiny eye. 🌀 🤯

Yep, re: "won't catch up".

The planet Earth as seen from GOES-19’s first full day as GOES-East.

To be clear: this would mean the *increment* of the increase in 2024 is itself the largest on record (in addition the value being the highest on record, which unfortunately happens essentially every year in our rapid warming era). That's...not great (as Glen discusses downthread).

*sigh*

Thinking of the many hard-working and skilled federal employees fired today from the NWS. Your contributions over the years have helped the NWS and its ability to fulfill its mission of protecting life & property. This is a loss for the NWS and for the nation.

Zack is a top-tier climate scientist and data visualization wizard. This did not need to happen.

I’m so sorry, please let me know if we can do anything. It was your Twitter account that I came across almost 10 years ago that inspired me to go back to school and study climate science.

I can’t wait until these Santa Ana winds are over. Let’s get to the weekend and get some rain in SoCal.

Do you have 70mph + <10% relative humidity + no rain in 8 months at your house?

Oh come ON now. This new JWST image is just ASTOUNDING.

I feel like I’m falling looking into it, and that I would fall forever, and that I would enjoy it.

Close up view showing fraction of metals. Fun stuff.

Just had a sample of the Eaton Fire ash that is in my driveway run on the department XRF. Is there titanium (new house paint)? Yup. Lead (old house paint)? You betcha. Heavy metals? Check. Treat that ash like it's toxic folks (because it is)

UGH. "Our weather pattern for next week features a deep trough of low pressure covering most of the nation`s interior with high pressure over the Pacific. That puts SoCal in northerly offshore flow seemingly forever." forecast.weather.gov/product.php?...

It’s so dry here.

physics of climate impacts 101:
- Stuff gets hot (worse heatwaves)
- Hot air holds more water vapor (heavier rainfall)
- Hot air is thirstier air (higher drought risk)
- Warm water is hurricane food (stronger storms)
- Hot water expands and hot ice melts (sea level rise)

five time series of global mean surface temperature changes starting low and noisy in the 1850s - rising clearly since the 1960s - and showing 2024 was clearly the warmest.

All surface temperature products for 2024 are now live.

All show 2024 is the warmest year (very clearly).

The estimates of the change since the pre-industrial (1850-1900) are more uncertain but range from 1.46 to 1.62ºC.

It is therefore *likely* this was the first year that exceeded 1.5ºC.

Although first responders were successful in keeping the fire from JPL, over 150 JPLers have lost their homes. Here’s link to the Caltech/JPL disaster relief fund if you’re so inclined: caltech.imodules.com/controls/ema...

Thanks for your support of our JPL family.

Here's a schematic I published in this 2021 piece to illustrate how even a modest delay in onset of rainy season in Southern California can dramatically amplify wildfire risk by lengthening seasonal overlap between dry vegetation and strong offshore winds during Oct-Jan. #CAfire

Today is the date where the Contiguous U.S. has reached the midpoint of winter. Of course this is an average and varies quite a bit from west to east. 🥳

Every state in the contiguous U.S. is touched by drought now. Some entire states are in some degree of drought, including Florida.

Beautiful

Line graph time series showing global land surface temperatures (90°S to 90°N) in a red line and global mean surface temperatures (90°S to 90°N) in a blue line. Temperatures are averaged annually from 1900 through 2023. Line trends are also shown from 1990 to 2023. The land is warming faster than the global mean.

As a reminder, land areas (where we live) are warming around twice as fast as the oceans. Subsequently, most of us are 'experiencing' temperatures rising faster than the global mean record.

That’s a good combo to study, best of luck on your studies!

Landed in Salt Lake City for work - holy AQI.

This is from February of this year. And from what I’ve read it’s gotten worse since then. We’re in the purple. Sources below.

Really important to stress the non-linearity of the climate system.

However many times this was on your feed today, it wasn’t enough. Absolute perfection.

Gorgeous!
