Some non-climate fun: the Bifröst is open at the moment.

Fueling the Future: Why EVs Are Better for the Environment

Let’s bust some environmental myths about EVs and internal combustion engine (ICE) cars, which include gas and diesel vehicles.

Prescient foreshadowing, "Darkness crept back into the forests of the world. Rumor grew of a shadow in the East, whispers of a nameless fear, and the Ring of Power perceived its time had now come."

I've always been fascinated by the power of visual storytelling, interspersed with topical humor to drive points home. When I was with NASA I explored this in many of my internal educational presentations. The world that was, the world that is now and the world may yet come to pass:

Scientists understand that the global response of land-based ice to global warming takes time, such that the sea level rise response of that land-based ice continues for millennia after the warming that drove it stops. Future SLR scenarios, from the recent IPCC AR6, by the (boring) numbers:

IPCC AR6, WG1, Chapter 9, Table 9.10, P. 1305, shows the ongoing 10,000-year commitment to future sea level rise

Some people (you know the disingenuous type) like to point to the GISP2 temperature record (an ice core retrieved from the summit of Greenland) as evidence that it's not that warm recently. Let's look at the FULL Greenland summit temperature record, from NASA:

Looking at the ice core greenhouse gas data, adding in modern observations, sheds clear light on the relative impacts that humans have had on Earth's atmosphere, from 800,000 years Before Present through 2023. That ain't natural.

From the Did-You-Know files: The warming driven by human activities since 1750 is over 291 times greater than the slight extra warming coming from the Sun itself over that same time interval. It isn't the Sun driving recent observed warming. It's us.

Sometimes it's instructive, to see the context of where we are now vs the conditions that allowed agriculture and civilization to develop.

October 2024 was about 1.49 C above the IPCC's preindustrial 1851-1900 baseline. And no, "cooling" since October 2023 is not statistically significant.
