The planet is heating up. Storms, droughts, and wildfires are getting worse.

What if we could "hack" the climate to cool things down?

Geoengineering is the idea of using science and technology to control Earth’s weather and fight climate change. But could this "weather control" go wrong?

How Geoengineering Works

Scientists are exploring two big ways to control the climate:

1. Blocking the Sun to Cool the Planet

Spraying tiny particles into the sky to reflect sunlight
Mimicking volcanic eruptions (volcanoes naturally cool the Earth after big eruptions)
Launching mirrors into space to deflect heat

2. Sucking CO₂ Out of the Air - Direct Air Capture

Giant "air filters" that remove pollution
Adding nutrients to the ocean to grow CO₂-absorbing algae
Planting “super trees” that absorb extra carbon

Example: Iceland is already using "air-sucking" machines to remove CO₂ from the atmosphere and turn it into stone underground!

The Risks—Could It Backfire?

Geoengineering sounds like a superhero fix—but what if it causes NEW problems?

What if blocking the Sun changes rainfall patterns and causes droughts?
What if some countries benefit while others suffer?
What if people stop cutting emissions and rely only on technology?

Example: Scientists warn that if we suddenly stop using geoengineering, the Earth could heat up even faster than before.

Fun Fact

In 1815, a giant volcano erupted in Indonesia, blasting so much ash into the sky that it blocked the Sun and cooled the entire planet for a whole year!

The result? "The Year Without a Summer."

Snow fell in June—even in places that usually never see snow!
Crops failed, leading to massive food shortages worldwide.
The sky was so hazy that people thought the world was ending.

Now, scientists are considering doing something similar on purpose to stop global warming. But could blocking the Sun bring unintended chaos?
