Brasil Pode Ficar Inabitável em 50 Anos Devido ao Calor Extremo

Midwest, Northeast, North, and Southeast Are Among the Most Vulnerable Regions; Understand the Criteria and Health Risks.

A NASA study revealed that parts of Brazil may become uninhabitable by 2073 due to extreme heat. Combining temperature and humidity, regions such as Midwest and Northeast will face risks of thermal collapse. Learn which areas are threatened and how heat can affect human health.

The NASA research points out that areas in the Midwest, Northeast, North, and Southeast of Brazil are vulnerable to uninhabitable conditions in the next 50 years. The criterion used goes beyond temperature: it considers the combination of heat and humidity, called wet-bulb temperature, which amplifies the effects on the human body.

Understand the Wet-Bulb Temperature Criterion

The wet-bulb temperature is measured with a thermometer covered by a wet cloth. Values above 35°C make survival practically impossible. In Brazil, regions with high humidity and heat above 37°C (with 70% humidity) may reach this threshold, posing a risk of death even in the shade.

Diseases and Risk of Organ Failure

Extreme heat is linked to 27 lethal disorders, including:

Organ failure (when body temperature exceeds 42°C);
Worsening of cardiovascular and respiratory diseases;
Brain damage.
Between 2000 and 2019, heat caused 489,000 deaths/year worldwide, according to WHO and WMO – an underreported number.

Beyond Brazil

The study highlights that South Asia, the Persian Gulf, parts of China, and Southeast Asia may also become uninhabitable. The wet-bulb temperature criterion was applied globally, using satellite images and climate projections.

How to Mitigate the Effects? Urgent Measures Highlighted by the NASA Study

To avoid this scenario, NASA recommends:

Reducing greenhouse gas emissions;
Combating deforestation and wildfires;
Implementing early warning systems for heatwaves;
Promoting sustainable consumption of natural resources.

The NASA study is a warning for immediate actions. Extreme heat is not just an environmental crisis but a public health threat. Without global measures, entire regions of Brazil and the world may become inhospitable in decades.

How to Mitigate the Effects? Urgent Measures Highlighted by the NASA Study

A village with 115 inhabitants wants new residents: it offers a house, a job, up to 44 thousand euros in benefits, almost free rent, an annual grant of 8 thousand euros for 3 years, and a 20 thousand euro incentive for businesses in the mountains of Italy.

NASA is offering US$ 750,000 to people from anywhere in the world who solve a problem that could decide survival on Mars: creating food for astronauts without relying on resupply from Earth.

While countries spend billions to draw water from the sea, a Nobel-winning scientist creates a container-sized machine that extracts up to 1,000 liters per day from dry air and uses ultrasound to release water in minutes, even in the middle of the desert.

Belgium will sink 23 giant concrete caissons, each weighing 22,000 tons, in the North Sea to build the world’s first artificial energy island 45 km off the coast, forming offshore electrical walls.

New microwave that can replace three appliances hits the market: Sharp launches 3-in-1 model that combines air fryer, convection oven, and heating in 0.9 cubic feet for small kitchens

While Brazil has been discussing bullet trains for 16 years, China delivers 5 new high-speed lines in 2026, surpasses 50,000 km of HSR, and moves 1 billion passengers in a single year.

With an 88-meter wingspan, a capacity of 250 tons, six engines, and 32 wheels, the Ukrainian giant became the greatest symbol of extreme air transport and one of the most impressive machines in aviation history.

While traditional masonry can take months, a Brazilian company sells houses that arrive ready-made on a truck, install in up to 8 hours, and already come with electrical, plumbing, bathrooms, and finishes.

With R$ 189 million and 10 Brazilian companies, Brazil is developing a 12-meter national rocket to launch satellites of up to 30 kg from Alcântara and try to conquer the “key to space” without depending on powers like the USA, Russia, China, and India.

Cheap used cars can turn into a headache: 7 models up to R$ 50,000 that seem like a good deal, but can wipe out your savings at the mechanic’s

Mangroves hide a billion-dollar water cleanup, remove 960 thousand tons of nitrogen per year, and reveal an environmental power that many people hadn’t even imagined existed.

The delivery of a 15 m² container studio apartment, furnished with a bed, nightstand, wardrobe, slatted panel headboard, custom-designed kitchen, and a corner shower enclosure in the bathroom. The client will use the house on weekends.
