Feeling the Effects of 260,000 Federal Jobs Lost

"Last July, a flash flood in Texas killed more than 100 people. The National Weather Service’s forecast was very good, Spinrad said, but there was no one filling a position responsible for warning local officials and emergency managers at the time."

For example, the climate bank bill was Amendment 2, which has an "action" listed as consol. amdt. C which was adopted by a roll call vote 121-26. But I don't see it in an engrossed bill (H5157) and I'm hearing maybe it wasn't adopted?

Hey #mapoli folks! Can anyone explain to me how "consolidated amendments" in the MA legislature? There were 3 on H5151 that were adopted but I'm hearing that individual amendmts listed in each consolidated amendment may not have made it into the package?

UB moves to decarbonize North Campus UB's Clean Energy Master Plan seeks to recover waste heat from the Empire AI supercomputing center and transform how the campus uses energy.

β€œIn short,” Hubbard says, β€œdecarbonization is an investment strategy, one that when done right is the same cost, or even less expensive, over the long term than the business-as-usual approach.” Kudos to U Buffalo!

Because this is social media, I should clarify that I'm not saying the NYSERDA analysis is industry funded but just that analysis showing price impacts this large from climate policy often have some pretty debatable assumptions.

Climate law mandates could cost New Yorkers $4,000 in higher energy bills, state analysis shows The New York State Energy and Development Authority sent a memo to Gov. Kathy Hochul warning about the costs of complying with the state’s Climate Leadership and Community Protection Act.

Hey #energysky! Has anyone dug into the actual NYSERDA analysis here? I've seen a lot of industry funded analysis of climate policy over the years and the assumptions really matter!
