The TLDR is that The Trump administration is deleting federal climate data and reports to make it harder to track, regulate, or respond to climate change as part of a broader effort to boost fossil fuel interests because the morons in the Heritage Foundation told him to. Trump sold another part of the US. Shocking.

As long as we're stuck in the type of secrecy Einstein so objected to, nudging ecosystems back to within sustainable margins using geoengineering will be way too risky anyway. However, should a situation arise where such a worldwide orchestrated attempt becomes plausible, we'll need as much data as possible if projections are to match the actual outcome of our meddling... If too much data has gone missing (or has become unreliable as a result of being tampered with), this approach will no longer be an option at all.
