I had an engagement with blogger, failed California gubernatorial candidate, and self-identified reporter Michael Shellenberger this past week, which started out being about this new paper being heralded by climate skeptics as disproving global sea-level acceleration. (LONG 🧵)

Klimaatraad: Nederland moet groots dromen over meeveranderen met klimaat

Bij het bouwen van huizen, fabrieken of infrastructuur moet Nederland kijken of het ook geschikt is voor het klimaat van de komende honderd jaar.

📢 New paper in Nature! New geological data gives more insight into rate and magnitude of global sea level rise following the last ice age. This is of great importance to understand the impact global warming has had on the ice caps and sea level rise.

Strong statement from @agu.org

WHAT YOU DIDN'T HEAR LAST NIGHT BUT NEED TO KNOW
Last night, President Trump addressed a joint session of Congress. Titled "The Renewal of the American Dream," there was heavy emphasis on the economy, border security, and foreign relations, but what you didn't hear was the realities of a hollowing out of the federal workforce that has weakened critical scientific expertise, abdicated climate leadership, shrunk important research, and frozen global cooperation. Not a dream but a nightmare of loss and uncertainty for the United States and the world.
Declaring that "America is back" and "at the dawn of a golden age," the president highlighted more than $1.7 trillion in investments made since he took the oath of office, including increases in energy production.
But missing from last night is the reality that fast and furious halts to science funding along with sweeping terminations of federal workers at key agencies is ushering in a dark age of retreat on climate research, leadership, and international engagement.
The United States is becoming increasingly isolated, from our withdrawal from the World Health Organization and the Paris Agreement to a pull back from the Intergovernmental Panel on Climate Change, blocking future participation of federal scientists and diplomats.
The nation's vital science is cut off from the world.
The president spoke of "a comeback" - one of economic vigor and committed deregulation, but it is chaos that is reigning with widespread and indiscriminate cuts to federal research funding.

You also did not hear about how proposed funding cuts are causing significant distress among research institutions.
Universities are implementing hiring freezes and reducing Ph.D. admissions. The uncertainty is prompting concerns about a potential brain drain, with researchers considering opportunities abroad if domestic funding continues to dwindle.
If cuts to agency workforces and funding freezes were not enough, just before the president's speech the Administration informed two pivotal centers for weather forecasting that their leases would be canceled.
These are not simply buildings, but nerve centers for lifesaving meteorological information. The NOAA Center for Weather and Climate Prediction in College Park, Maryland, ensures data is correctly processed for accurate forecasting. The Radar Operations Center in Norman, Oklahoma, works to improve and repair the nation's aging fleet of Doppler weather radars.
The president praised farmers in his address, declaring a new day for their productivity and success, but without reliable weather data how can they bank on that bright future?
In his closing, the president vowed to "conquer the vast frontiers of science." But with scores of scientists being fired or muzzled and with funding frozen, one must ask:
How do we do that?
Sadly, at the moment, the state of our science is not strong, but the resolve of our community in Earth and space sciences to restore and renew it is.

All websites that depend on NOAA data should display something like this.

earth.nullschool.net

Weather and climate data shown on this website and countless others are at risk.

The National Oceanic and Atmospheric Administration (NOAA) is the U.S. agency responsible for global weather forecasting, hurricane prediction, ocean observation, and many other services vital to public safety. Its satellites, supercomputers, and research teams provide essential data that help us understand our planet and protect lives.

On February 27, the new U.S. administration initiated mass firings at NOAA. These actions are unethical and deeply disruptive to the talented scientists and engineers who dedicate themselves to the public good. The firings, along with expected budget cuts, have serious implications for the availability and quality of weather forecasts produced by the United States. They must be reversed immediately.

Much of the data on this website is downloaded directly from NOAA's servers. In this environment of uncertainty, access could be disrupted at any time. While I'll strive to keep all features on this website functional and switch to alternative data sources if necessary, some datasets have no substitute if they go offline.

If this concerns you, speak up. Share on social media. And if you're in the U.S., contact your representatives.

Out now: we studied expert perspectives on living-with-water strategies (as opposed to more physical flood infrastructure) and found that although there are different perspectives to what role living with water will play in the future, experts agree at least some making room for water is needed.
