The photo was taken by photographer Jeremy Gilchrist, describing exactly what happened in Durham, North Carolina (USA) in recent days without the need for editing. And if you're curious about what makes the yellow cover the whole city, the answer is . pollen.

More precisely a lot of pollen. They come from the forests around the city, clinging to the clouds, turning the sky into yellow green.

Gilchrist said that when he saw the sky begin to turn "weird", he used a drone to fly high to capture the whole city.

"What is observed is really unexpected," - he said.

In the afternoon of the same day the pictures were taken, a storm came and made the atmosphere more airy. However, according to the Weather Channel, the level of pollen is still at a record high in the United States.

This is really a very scary phenomenon. For those who do not know, pollen is a powerful allergen, especially affecting people with asthma . If eligible, an allergic reaction can cause a more severe reaction than normal, even a fatal respiratory failure.

Pollen covers the whole city of Durham.

According to Gilchrist, conditions in the city of Durham at this time are also perfect for spreading pollen. The air is dry and cool, causing pollen to spread continuously into the air whenever the wind blows.

The Weather Channel predicts that this pollen disaster will last for many more days. This is a consequence of climate change: a warmer climate makes the growing season of flowers longer, and those who suffer from allergies suffer longer.

"The evidence is unclear, but the reality shows that the growing season of toxic plants is prolonging, causing pollens to attack people with allergies" - quoted Charles W. Schmidt, expert. research on climate change.

" Warm temperatures and high CO ₂ levels will help plants grow stronger, producing more pollen than usual."
