Yes, Swiss scientist Fritz Zwicky coined the term “dark matter” which is impressive, but he also coined the term “spherical bastard” to describe people who are bastards no matter which way you look at them, and I think that should be celebrated more.

Calcification (i.e., formation of shells by marine organisms) uses bicarbonate and releases CO₂, leading to a net flux of CO₂ into the atmosphere. Conversely, dissolving corals will enhance ocean uptake of atmospheric CO₂.

If you take the time to read the whole Gates memo (which I did), the bulk of the content was mostly solid and encouraging. Really! It was the FRAME that was off--very off, from the first line. And when your framing is off, then how you make decisions and set priorities is off. THAT'S the problem.

My quote from an Axios interview, stating that: People often think of climate change as a separate bucket at the end of a long row of other buckets of problems we're trying to fix that are wrong in the world," Hayhoe told Axios.
This includes poverty, disease and access to clean water.
"Climate change is not a separate bucket," Hayhoe said. "The reason we care about climate change is that it's the hole in every bucket."

NEW: Hundreds of NASA employees have filed a letter of formal dissent. "We are compelled to speak up when our leadership prioritizes political momentum over human safety, scientific advancement, and efficient use of public resources. The consequences for the agency and the country alike are dire."

The Voyager Declaration
Dear Interim Administrator Duffy,

In light of your recent appointment as Interim NASA Administrator, we bring to your attention recent policies that have or threaten to waste public resources, compromise human safety, weaken national security, and undermine the core NASA mission. We, the signatories of this letter, dissent from these policies, and raise these concerns because we believe strongly in the importance of NASA's mission, which we are dedicated to uphold.

Major programmatic shifts at NASA must be implemented strategically so that risks are managed carefully. Instead, the last six months have seen rapid and wasteful changes which have undermined our mission and caused catastrophic impacts on NASA's workforce. We are compelled to speak up when our leadership prioritizes political momentum over human safety, scientific advancement, and efficient use of public resources. These cuts are arbitrary and have been enacted in defiance of congressional appropriations law The consequences for the agency and the country alike are dire.
Our Shared Commitment to Dissentin� Opinions

We share a commitment to dissenting views in accordance with NASA Policy Directive 1000.0C,

NASA supports full and open discussion of issues of any nature (e.g., programmatic, institutional), including alternative and divergent views. Diverse views are to be fostered and respected in an environment of integrity and trust with no suppression or retribution. (NPD 1000.0C, Section 3.5.5)
Employees across the agency have raised concerns about recent actions to NASA leadership, yet we remain pressured to implement harmful measures. We choose to write to you directly because: (I) as Interim Administrator, you are the final step in the chain of Technical Authority, and (2) the issues we raise are agency-wide, rather than project-specific.
As defined in NASA Procedural Requirement 7120 5F, Formal Dissent is "a substantive disagreement with a decision or action that an indiv…

• We dissent to changes to NASA's Technical Authority capacities that are driven by anything other than safety and mission assurance. The culture of organizational silence promoted at NASA over the last six months already represents a dangerous tum away from the lessons learned following the Columbia disaster. Changes to the system of Technical Authority, as suggested would be made in the June 25th NASA Town Hall, should be made only in the interests of improving safety, not in anticipation of future budget cuts.
• We dissent to the closing out of missions for which Congress has appropriated funding because it represents a permanent loss of capability to the United States both in space and on Eatlh. Once operational spacecraft are decommissioned, they cannot be turned back on. Additionally, cancelling missions in development threatens to end the next generation of crucial
observations.
• We dissent to implementing indiscriminate cuts to NASA science and aeronautics research because this will leave the American people without the unique public good that NASA provides. Basic research in space science, aeronautics, and the stewardship of the Earth are inherently governmental functions that cannot and will not be taken up by the private sector. Furthermore, NASA has a nearly threefold return on investment in economic activity, and supports national security by ensuring the United States maintains its lead in science and technology.
• We dissent to NASA's non-strategic staffing reductions because they will jeopardize NASA's core mission. Thousands of NASA civil servant employees have already been terminated, resigned or retired early, taking with them highly specialized, irreplaceable knowledge crucial to carrying out NASA's mission.
• We dissent to canceling NASA participation in international missions because in doing so, NASA is abandoning America's allies. To date, 55 nations have signed on to the Artemis Accords, and withdrawing support from missions with our long-s…

We stand in solidarity with our colleagues at the NIH and EPA who have released similar statements concerning the administration's actions at their respective agencies.

We dedicate this letter to Gus Grissom, Ed White, Roger Chaffee, Dick Scobee, Michael J. Smith, Ronald McNair, Ellison Onizuka, Judith Resnik, Gregory Jarvis, Christa McAuliffe, Rick Husband, Willie McCool, Michael Anderson, Kalpana Chawla, David Brown, Laurel Clark, and Ilan Ramon. Their legacies underpin every conversation about our shared commitment to safety and dissenting opinions at NASA.

If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org.
