Four new international Working Groups launched by the Past Global Changes (PAGES) bring together global expertise in paleoclimate science. 🌍

Read an article about these working groups and where some of the leaders come from.

β€’ Squandering time and embedding permanent climate damages
β€’ Squandering opportunity to reshape to a clean energy economy, magnifying economic damages
β€’ Without even the arguable selfish benefit of sovereign wealth - exporting profits.
β€’ How is it justifiable by any measure of national interest?

And, to catch an all too familiar issue, a gendering error at the end.
β€˜Professor Davies said future changes in Antarctica would have significant repercussions elsewhere.

"Though Antarctica is far away, changes here will impact the rest of the…" he said.’

A fantastic season for the Million Year Ice Core Project - moving beyond setup and pilot drilling to commissioning the new deep drill and working in a fluid-filled hole. This drill site offers an exciting opportunity to drill the longest continuous ice core record.

You can't... repeal... a scientific finding. At that point it's just called lying about it.

If only we had some sort of report - a risk assessment if you will - that told government if this is all going to get better or worse...

The fate of the planet’s coastlines depends on how fast Antarctica’s ice sheets melt. We don’t know what’s coming Some regions of the continent have enough ice to push up sea levels by 15 metres if they all melt, but researchers don’t yet fully understand the consequences

An excellent article with many insightful observations. In an era where Trump’s wild excesses are often downplayed/softened in mainstream media, it’s encouraging that Australians seem clear-eyed.

I’m uneasy about the Age headline. The 2005 briefing by Geoff Love was pretty blunt about the risks.
Why isn’t the headline β€˜Howard government ignored scientists warnings’??
Headline implies the climate science was wrong - it wasn’t.

This quote and a novel, poignant image is worthy of attention as another year begins. Human conceits rage around us and kindness is too scarce.

Nice encapsulation. The only consolation in a local sense is if it keeps money in the community rather than e-commerce.
