Fascinating detail in this story: the Korubo, an Amazonian group who first made contact with the outside world in 1996, farm bananas (from Papua New Guinea) and melon (an Old World fruit):
Story by @domphillips, a wonderful journalist currently missing in this part of the Amazon.
Of course it's possible they only started farming them since 1996. But I wouldn't be surprised if they were already doing it. Even "uncontacted tribes" are embedded in trading networks that span the globe.
India's heatwave is terrifying, pushing up ever closer to tipping points where even healthy humans can die after just hours of exposure outdoors. My column with @rpollard:
@rpollard A term that hitherto is mostly known to meteorologists and climatologists is likely to become grimly familiar over the coming years: wet-bulb temperature, the combination of heat and humidity that determines our ability to cool our bodies down via sweating.
@rpollard When people say "it's hot, but it's OK because it's a dry heat" they're describing a real physiological process.
Human bodies cool down by sweating, but to do that the air needs to be able to absorb the moisture on our skin. When humidity rises, that gets harder.
Indonesia, the biggest producer of palm oil, this week put an embargo on exports of palm oil.
The idea is to calm domestic cooking-oil prices ahead of the Eid al-Fitr holiday -- but putting the blame and burden on exports is misdiagnosing the problem.
Although food accounts for about 70% of palm oil used globally, the real swing factor in the market is transport fuel.
In the 2010s, production boomed and then collapsed as the EU blended palm into biodiesel, and then imposed anti-dumping tariffs. Another boom is now underway.
