With Latest Rollback, the U.S. Essentially Has No Clean-Car Rules

Like to breathe?
Yea, me too.
Like a climate that sustains life?
Yea, me too.
Like to make less impact on Earth?
Yea, me too.
…then there is the U.S.A.

Trump orders Pentagon to buy power from coal plants Trump declared coal essential to U.S. national and economic security last April.

Another giant step backwards for the health of the planet.
Another giant step forward for those who need even more money.
Both oil and coal are too valuable, as substrates, to be burning.
Shame to the greed.

Another awful day in American history.
Another life lost in the name of…what?
None of this should be happening.
Where are the adults; politicians with brains; policy makers?
As for this adult, I am ashamed to be American. β€˜Nuff said.

Trump’s post on Rob Reiner sparks outrage from lawmakers and celebrities President’s statement blaming acclaimed director’s death on his dislike of him described as β€˜disgusting’ and β€˜vile’

A major loss of an outstanding creator.
An amazing gain of a true meathead.
Don’t ever treat any human in such fashion.

Here's what the remediation for environmental issues may look like at Burnham Yard The historic railyard likely contains subsurface contamination from decades of industrial use that will need to be addressed before the planned stadium.

Thanks @spencersoicher.bsky.social @nexton9news.bsky.social for a story on the importance of environmental contamination, site clean-up and of course, microbes!🦠 🦠

CBS Canceling β€˜Late Show With Stephen Colbert’ After Next Season

I once had a joyful evening in the Ed Sullivan Theater watching magic happen in front of me. An educated, civil, democratic society values the jestersβ€”Stephen Colbert is a master teacher we all learn from.

Apparently CBS Paramount does not, enhancing our decline.

Hydrothermal Hazards on Display in Yellowstone National Park - Eos Tourists and officials were startled by a hydrothermal explosion at Black Diamond Pool in July 2024. Geoscientists are working out how and why it occurred to better understand these hazardous events.
