New study published in the journal AGU Advances, shows that firestorms will block the Sun and trigger a “Little Ice Age” that will last for thousands of years. This will lead to crop failure and famine in the ocean.
“In the first month after the explosion, the average global temperature will drop by about 13 degrees Fahrenheit (7 degrees Celsius – UNIAN). This is more than during the most recent ice age, which lasted more than 100,000 years, when mammoths became extinct,” the study says. .
Lead author Dr Cheryl Harrison of Louisiana State University said: “Once smoke enters the upper atmosphere, it spreads around the world and affects everyone.”
However, Russia’s invasion of Ukraine has brought to the fore the threat of nuclear war, and this study provides for the first time a stark picture of the environmental impact if Putin had reached for the nuclear button.

Analysis shows that ocean temperatures will drop rapidly and will not return to pre-war levels even after the smoke clears.
As the planet cools, the sea ice will expand and block major ports, including Beijing, Copenhagen and St. Petersburg.
The ice will then spread to normally temperate coastal regions and hamper navigation across the Northern Hemisphere, while making it difficult to get food and supplies to some cities like Shanghai.
A sudden drop in light and sea temperature will kill algae, the backbone of the marine food web.
The researchers said fisheries and aquaculture would be shut down due to “virtual ocean famine”.
One model simulates the use by the US and Russia of 4,400 100-kiloton nuclear warheads to bomb cities and industrial areas.
In this case, the fires will release more than 150 billion tons of smoke and black carbon into the upper atmosphere, absorbing sunlight.
Recall that during a recent meeting with Lukashenka, Putin said that within the next few months he would transfer to Minsk the Iskander-M complexes, which can be used, including nuclear weapons.
