Earth's climate doesn't operate in isolated regional pockets. What builds up as a temperature anomaly in the tropical Pacific eventually shows up in the Indian monsoon, in southern Africa's water table, in Australia's wheat harvest. El Niño makes that global connectivity visible in the most direct way possible — through droughts, floods, and food shortages distributed across six continents simultaneously. El Niño events are estimated to affect crop yields on at least a quarter of global croplands. The one confirmed for 2026 is shaping up to be one of the strongest on record. NOAA's Climate Prediction Center gives a 63% probability of a very strong event between November 2026 and January 2027 that could rank among the largest in the historical record since 1950 . Ocean currents transfer significant amounts of heat from Earth's equatorial areas toward the poles and play an important role in the climate of coastal regions worldwide. The map below shows the global ...
400,000 plant species and we built entire civilizations around two shrubs. Not wheat, not rice , not anything that keeps you alive. Two plants whose main offering is a chemical that delays the feeling of tiredness for a few hours. Cultures that never had contact with each other, separated by oceans and centuries, independently figured out that these particular plants were worth domesticating, trading, and eventually growing on a continental scale. The maps published by VividMaps using SPAM 2020 V2r0 data illustrate the regions where these two species are cultivated. Coffea began in the forests of Ethiopia and eventually reached every continent with a suitable climate, which turns out to be a fairly specific set of places. Camellia sinensis moved outward from Chinese hillsides, first along trade routes and later through deliberate colonial transplantation into India, Sri Lanka, and East Africa. Both plants traveled well because dried leaves and roasted seeds don't spoil easily....
