Video report: Arctic warming and scientific conservatism

Climate News Links on April 3, 2022

A personal story on Arctic climate change filled with facts together with discussion of how ‘conservative science’ nobbles urgency of action.

What Arctic climate tells us – It’s worse than we are told: Why science communication is conservative.

History: First real evidence for abrupt climate change

Climate News Links on April 3, 2022

1969 Greenland ice cores provide convincingly accurately timed evidence for abrupt major changes in Earth temperatures and global warming.

Wally Broecker divined how the climate could suddenly shift: The shutdown of an ocean conveyor belt could cause abrupt climate change

It was the mid-1980s, at a meeting in Switzerland, when Wally Broecker’s ears perked up. Scientist Hans Oeschger was describing an ice core drilled at a military radar station in southern Greenland. Layer by layer, the 2-kilometer-long core revealed what the climate there was like thousands of years ago. Climate shifts, inferred from the amounts of carbon dioxide and of a form of oxygen in the core, played out surprisingly quickly — within just a few decades. It seemed almost too fast to be true.

Editor’s note: See Broecker’s 1975 paper, Are We on the Brink of a Pronounced Global Warming? in Science, that gave us early warning 47 years ago on what might be happening. How different our future might have been if humanity took that warning seriously.

Expert explains NB4 polar temperature extremes

Climate News Links on March 26, 2022

Yale Climate Connections‘ Bob Hensen discusses and explains the unimaginable heat episodes observed at in north and south polar regions

A research caravan seen from above by a research drone in early 2020 on the East Antarctic Plateau south of Concordia Station. Concordia recorded its highest temperature in more than 15 years of data collection on March 18, 2022 – a date when temperatures are normally closer to their winter lows than summer highs.

How this month produced a mind-boggling warm-up in eastern Antarctica (and the Arctic): Two atmospheric rivers surge toward opposite poles:

The bloodless term “anomaly” doesn’t do justice to the stupendous temperature departures seen across parts of both the Antarctic and Arctic in mid-March 2022. With the initial shock now behind them, scientists are taking stock of exactly what happened and what it might portend.

Extreme Antarctic heat is NB4 for any time of year!

Climate News Links on March 22, 2022

38 °C above normal for any day of any year is a Never Before (NB4) extreme temp for Antarctica. Increasing number of NB4s says worse to come!

State of the Arctic in 2020: bad news for our future

William P. Hall on February 26, 2022

Amer. Meteorological Society’s 2020 State of the Climate reports accelerating Arctic warming (Arctic amplification) that drives world climate

Zach Labe samples that data to show midwinter temperature over the Barents and Kara Seas has risen by more than 2 °C per decade!

Note: over the next few days I will be posting a comprehensive post on the full State of the Arctic article and the warnings we should be taking from it.

Wrapping ice and snow to slow/stop melting

William P. Hall on February 13, 2022

Amazing breakthrough technology: cover ice and snow with ‘green’ radiative cooling foil to slow/stop melting and even help freezing

by Jinlei Li et al. 11/02/2022 in Science Advances
Protecting ice from melting under sunlight via radiative cooling: Here, we demonstrate that a hierarchically designed radiative cooling film based on abundant and eco-friendly cellulose acetate molecules versatilely provides effective and passive protection to various forms/scales of ice under sunlight. This work provides inspiration for developing an effective, scalable, and sustainable route for preserving ice and other critical elements of ecosystems.

VC1 Editor’s comment: The cost-effectiveness of this technology remains to be proven in practice. However, the the science appears to be sound, cooling effects of ultra-white paint have been proven in shopping center-scale commercial application, and the acetate film is made from renewable materials and should be safely biodegradable in application.
