🚗⚡ The future is electric! ⚡🚗 EVs = cleaner air, fewer emissions, and no more gas station stops! 🌱💚 Ready to plug into a greener future? Read our guest post by @holly111888.bsky.social, my former amazing colleague from NASA's Climate website!

eco-nana.comFueling the Future: Why EVs Are Better for the EnvironmentLet’s bust some environmental myths about EVs and internal combustion engine (ICE) cars, which include gas and diesel vehicles.

Thus, current events in the US can similarly be interpreted as a campaign of subjugation and power meant to do away with sovereignty/free will and to create one centralized power that rules/dominates over everything and everyone.

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:

Humans are causing all of the recent observed warming and offsetting the ongoing natural cooling of Earth’s surface at the same time. This recent observed warming is unprecedented over at least the past 100,000 years.

Nature can cause climate change but so do humans; right now, the human causes are happening much faster and are far stronger than natural causes. Humans have effectively wrapped a thin, silver space blanket around the planet and it warms accordingly.

The modern warming is about the same as that which warmed Earth's surface out of the last ice age into our warm Holocene interglacial, except that what took 10,000 years to happen naturally is now happening in less than 200 years.

Channeling Galadriel again, the end began with very slow, minute changes in Earth’s orbit. More sunlight reached the Southern Ocean surrounding Antarctica, warming it, releasing CO2, which further warmed the Earth and melted land-based ice in the Northern Hemisphere, driving yet more warming.

This natural feedback continued slowly over a 10,000-year period, with sea levels rising over 400 feet. Eventually, the orbitally-driven warming leveled off and as the newly exposed land in the Northern Hemisphere reforested, CO2 levels and temperature rises slowed and plateaued.

Other areas across the globe also saw much land exposed. Given the generally warmer nature of lowlands nearer the ocean than their higher ground neighbors, these lowlands would have been prime areas for flora and fauna to thrive.

Vast areas of land were exposed, due to global sea levels being some 400' lower than they are at present. Land bridges connected many disparate areas, allowing many species including humans to better disperse across the globe. For example, near present-day Australia:

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:

So where is that land-based ice responsible for those present and future contributions to sea level changes coming from? Ice, ice baby, from the IPCC's Land Ice - SLR Equivalents - AR5 WG1 - Chapter 4 - Table 4.1:

To illustrate that in a more fun way, commitments to future sea level rise are carbon pathway dependent, so estimates of such have some play in them. That same 10,000 year commitment to future SLR, in vertical units of the Rock (actor Dwayne Johnson):
