Incredible shot of the eye of Cat 5 Hurricane Melissa just moments before landfall in Jamaica yesterday taken by ESA's Sentinel 2 satellite. The amount of detail is breathtaking!

Hurricanes feed off of warm water. Watch how quickly the eye of #Melissa collapsed as it moved onto land and over the mountainous terrain of Jamaica, and how quickly it is reforming now that it has moved back over water! I will be adding this radar loop to my earth science lectures.

It appears that technosolutionism is very selective in the problems it offers to fix and quite transparently pro fossil fuels

Rolling back clean energy policies to “save” European industry will backfire. It may seem attractive in the short term, but it’s poor industrial policy in the long run.

Standing still on climate policy undermines competitiveness. Industry needs stability and long-term direction, not uncertainty.

To quote my friend @drkatemarvel.bsky.social, climate change won't make humanity extinct but we can do better than "not extinct". Raise your standards people!

Melissa is extremely dangerous, the strongest Atlantic hurricane to occur this late in the season.

Melissa reaches Category 5 — fueled by climate change-driven ocean heat | Climate Central Hurricane Melissa reached Category 4 strength, with winds of 140 mph, between Oct. 25 and 26 after undergoing extreme rapid intensification. The storm further strengthened into a Category 5 hurricane ...

This storm is a testament to what can happen if a hurricane doesn't blow out its eyewall too quickly. Melissa didn't seem to develop the unstable pinhole eye true of many cat 5 storms.

And of course a testament to the power of weather prediction that we can forecast these things days in advance.

#HurricaneMelissa is a buzzsaw of a storm this morning. Pressure still dropping. 901mb. Only six Atlantic hurricanes have reached barometric pressure in the 800s. The record for lowest pressure is Wilma (2005) - 882mb. Landfall expected in #Jamaica later today. #wx

As the Atlantic Ocean warms, climate change is fueling Hurricane Melissa's ferocity Hurricane Melissa has rapidly intensified into a Category 5 storm due to warming oceans linked to climate change.

“Climate change is fundamentally changing our weather. It does not mean that every single tropical cyclone is going to go through rapid or super-rapid intensification. However, in our warmer world, it will continue to increase the likelihood they do"

We study how Elon Musk's polarizing and partisan actions have impacted Tesla vehicle sales in the United States. Using county-level, monthly data on new vehicle registrations, we leverage how changes in vehicle sales over time diverge across counties with differing shares of Democratic and Republican voters. Without the Musk partisan effect, Tesla sales between October 2022 and April 2025 would have been 67-83% higher, equivalent to 1-1.26 million more vehicles. Musk’s partisan activities also increased the sales of other automakers' electric and hybrid vehicles 17-22% because of substitution, and undermined California’s progress in meeting its zero-emissions vehicle target

Melissa becomes third Category 5 hurricane of the extraordinary 2025 season Updates and summaries on tropical Atlantic activity... including easterly waves, tropical storms, subtropical storms, and hurricanes.

For only the second time in recorded history, an Atlantic season has produced three Category 5 hurricanes... the previous year was 2005. This puts 2025 in an elite class of hurricane seasons. It also means that nearly 7% of all known Category 5 hurricanes have occurred just in this year.

Finland has a goal to be net zero GHG emissions by 2035.

Emissions were declining, the LULUCF removals were strong, the plan was looking good, but then LULUCF collapsed.

Net GHG emissions have actually risen over the last decade!

Trojan gold: New US “standard” is another veiled attack on science Transparency, reproducibility, and acknowledging uncertainty are meritorious attributes of science that differentiate it from other human endeavors, such as politics. But they can also be subverted. In the United States, an executive order from the Trump administration called Restoring Gold Standard Science illustrates how this can be achieved despite it being cloaked in language that most of the scientific community would enthusiastically support. The order seeks to “to ensure that federally funded research is transparent, rigorous, and impactful, and that Federal decisions are informed by the most credible, reliable, and impartial scientific evidence available,” and it has already informed the Environmental Protection Agency’s (EPA) revised procedures for conducting risk evaluations for chemicals already in commerce.

If #Melissa finds its way south-southwest of Jamaica in several days, this environment has the highest ceiling for any Atlantic tropical cyclone I can remember.

Big, strong, slow-moving hurricanes like what #Melissa may become are when things like Oceanic Heat Content will start to matter a lot.

Plug-in hybrids perform much worse in the real world than their ‘official’ testing suggests.

This means more fuel burned, higher costs and more CO2.

The EU cannot weaken its car CO2 rules to allow space for these expensive, polluting cars.
