20 Amazing Hurricane Facts

Hurricanes are very powerful tropical storms (also known as tropical cyclones). When a tropical storm’s maximum sustained winds reach 74 mph (119 km/h), it is called a hurricane.

Hurricane is actually the name of a tropical cyclone that occurs in the Atlantic Ocean and the northeastern Pacific Ocean. In the northwestern Pacific Ocean; in the south Pacific or the Indian Ocean, for example, hurricanes are usually known as typhoons.

Hurricanes are classified by their sustained wind speed. The Saffir-Simpson hurricane wind scale (SSHWS) is a 1 to 5 rating based on a hurricane’s sustained wind speed. This scale estimates potential property damage.

Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. Category 1 and 2 storms are still dangerous, however, and require preventative measures.

Here are 20 amazing hurricane facts.

Amazing footage shows a boat speeding away as the Stromboli volcano erupts

On August 28, Stromboli volcano in Italy woke up a second time this summer. Tourists decided to ride a boat near the erupting volcano – but the journey turned out to be “fun”: they had to escape from the wave of pyroclastic flow. The eruption did not lead to casualties and destruction, but the tourists got really scared.

In fact, it was a really dangerous act. The pyroclastic flow is what makes composite volcanoes like Stromboli so deadly.

If we lose the Amazon rainforest, the consequences would be disastrous

There are big wildfires in the Amazon, the world’s largest tropical rainforest. Rainforests are the oldest living ecosystems and without a shadow of a doubt, the most vital habitats on Earth (the Amazon rainforest has been in existence for at least 55 million years). The Amazon represents over half of the planet’s remaining rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species.

Is Anthropocene a joke? A good read

According to some scientists, the world entered a completely new geological era called “Anthropocene“. And the reason is humans because we changed the world so much.

Now, a very good and detailed article written by the American science writer Peter Brannen and published on The Atlantic argues that the so-called Anthropocene is not a new era, it’s just an “event” in the Earth’s history. It’s a long but good read.

20 Amazing Elephant Facts

Elephants! Even though these largest existing land animals are loved, revered, and respected by people and cultures worldwide, they are actually close to the edge of extinction. The escalation of poaching, habitat loss, human-elephant conflict, and mistreatment in captivity are just some of the threats to both African and Asian elephants. So, we urgently need to take action to protect these amazing (and cute!) animals. Here are 20 amazing elephant facts.
