« Mitigating climate change requires ending the burning of fossil fuels. Offsets distract from this crucial task. »
There is a reason "offsetting" does not exist in the vast majority of cases of avoidable harm to human safety: it would be laughed off as physically absurd and outright fraudulent.
Somehow, in the single most catastrophic physical threat facing our species, it became accepted as normal

Carbon credits are failing to help with climate change — here’s why
The idea that emissions can be offset through projects that claim to avoid releases or to remove carbon dioxide from the atmosphere is fatally flawed.

Cool viewpoint on the impact of extreme temperatures on cell death. Perhaps some ecophysiology is required to articulate whole-plant observations and cellular mechanisms 🌿
Temperatures that switch on plant programmed cell death are now reality.
In our new viewpoint article @newphyt.bsky.social, we propose that studying the heat induced mortality at cellular level can contribute to strategies for heat stress mitigation.
