El Niño could return in 2026 with an 82% chance, warming the Pacific and reshaping Brazil’s climate, increasing the risk of heat, drought, and extreme rainfall for agriculture, energy, and cities on national alert.

Finland hides entire cities underground with gyms, playgrounds, and sports fields 25 meters deep, and now the whole world is lining up to learn how to build bomb shelters like the Finns.

Could artificial intelligence be heating entire neighborhoods? Study indicates that AI data centers release enough heat to raise nearby temperatures by up to 2.2 ºC and raise an alert about the new thermal pollution in cities.

Interesting facts

Few people know, but in Brazil there are cities with curious names like Feliz Natal, Não-me-Toque, and Varre-Sai, which may seem like random names, but originated from real events, local habits, and natural characteristics.

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

Almost 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland. Houses form a continuous row, and behind them, narrow agricultural strips emerge, creating one of the most unusual rural patterns in Europe.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

They planted a sea of eucalyptus to produce cellulose, but the monoculture turned into a green desert, dried up springs and rivers, and pushed families out of regions in Minas Gerais and Bahia.

Júlia Pimentel, an 11-year-old from Minas Gerais, independently invented a new formula to calculate the square root using simple addition and multiplication, and her method was published in one of the most important mathematical scientific journals in Brazil.

Described by astronauts as one of the most unlikely natural phenomena on Earth, the Okavango Delta spreads over up to 15,000 square kilometers in the middle of the desert and transforms Botswana into a living labyrinth of channels, islands, and flooded areas.
