Carbon dioxide removal is not a current climate solution — we need to change the narrative
Drastically reduce emissions first, or carbon dioxide removal will be next to useless.
www.nature.com
In recognition of us doing fuck all to reduce emissions, let me remind y'all that carbon dioxide removal (CDR) is useless unless we decarbonize drastically.

On January 1, many new laws come into effect worldwide. What new environmental law are you excited about?
In Hawaii, I'm excited about the new Green Fee on tourists to fund environmental projects.
As a bonus, there's a new law that prohibits parking within 20 feet of crosswalks and intersections.

Thirteen new Hawaii laws taking effect Jan. 1 will raise costs for tourists and uninsured drivers while expanding protections for families and consumers.

The measure, to be implemented by 2030, would also apply to crustaceans and cephalopod mollusks, including octopuses, all of which are recognized as sentient beings under British law.

@zhonggg.bsky.social is currently on a South Korean icebreaker in Antarctica because the US is no longer a serious country. The Trump regime got rid of our Antarctic icebreaker, Nathaniel B. Palmer, so for the first time in six decades we are without a dedicated Antarctic research vessel.

New law requires macadamia nut grown in and out of Hawaiʻi to be labeled accordingly.
I once brought mac nuts for my colleague in Australia. He looked at me awkwardly, and I thought he had an allergy. Then he told me that mac nuts were native to his region of Australia and gave me some in return.
