“The earth has reached its first catastrophic tipping point linked to greenhouse gas emissions, with warm water coral reefs now facing a long-term decline and risking the livelihoods of hundreds of millions of people, according to a new report.” www.theguardian.com/environment/...
Planet’s first catastrophic climate tipping point reached, report says, with coral reefs facing ‘widespread dieback’
Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns

A global analysis of crop yields suggests that each degree Celsius of warming by 2100 will reduce the food available per person by about 121 kilocalories per day.
Under a 3°C warming scenario “that works out to giving up breakfast for everyone”, says Andrew Hultgren. 🧪

World's farmers won't be able to keep up with climate change
Even if farmers change their agricultural practices in response to higher temperatures, five out of six staple crops will still suffer severe losses due to climate change

this seems to be very, very frightening
Preliminary data suggests that the global average increase in atmospheric CO2 concentration in 2024 will be a record.
Not just a little record, but 25% higher than the previous record.
(This is the global average, as opposed to Moana Loa)

Remember: the televised punishment & humiliation meted out to Zelensky just now could be done to any NATO ally facing similar aggression. The sense of sneering hostility & contempt by Trump & Vance isn’t specific to Ukraine.
