As 2025 approaches, people can't help but wonder: Will the winter of 2025 be unusually cold?

The impact of seasonal changes is more like a grand concerto. With the arrival of spring, daylight hours increase, temperatures rise, buds gradually break through the soil, flowers bloom, and insects become increasingly active. Bird migration patterns are adjusted by seasonal cues, and the arrival of the breeding season is often accompanied by a bustle of courtship, nesting, and chick-rearing. Summer's high temperatures and long days provide plants with abundant energy, intensifying competition among surface plants and increasing the physical demands of herbivores.

Winter, this season of snow, not only brings cold temperatures and beautiful snowy scenery, but also hides a wealth of fascinating scientific phenomena and knowledge.

Recently, scientists discovered that Earth's North and South Poles are about to reverse. This news has caused concern for many, as the Earth's North and South Poles are crucial to our lives.

Not long ago, news reports about the discovery of an "underground city" beneath the Egyptian pyramids garnered widespread attention in the archaeological community.

2.6 million years ago, at least three ancient hominin species likely roamed the African grasslands simultaneously, one of which may have been a previously undiscovered distant relative of "Lucy." They likely drank from the same river and foraged in the nearby grasslands. The only evidence of their existence is a few teeth buried in the soil.

Throughout human history, many civilizations flourished for a time, then vanished into the mists of time, leaving behind mysteries that can never be fully unraveled. The rise and fall of these civilizations are not only traces of history but also a part of human culture. Despite the tireless efforts of archaeologists and historians, many ancient ruins remain undeciphered. Lost cities, ancient empires, and mysterious ruins, shrouded in unanswered questions, captivate countless explorers.

Volcanic eruptions are natural phenomena characterized by short duration, high intensity, and destructive power.

When discussing hurricanes and typhoons, many people might think they're just different names for the same weather phenomenon. However, while both are types of tropical cyclones, there are some distinct differences between them.

The Sahara Desert wasn't always the arid, desolate landscape we know today. Between 14,500 and 5,000 years ago, the region was unrecognizable. During an unusually wet period known as the African Humid Period, it transformed into a lush tropical savanna. People roamed this green land for thousands of years before it was once again submerged by sand.

Tsunamis are massive waves triggered by submarine or coastal earthquakes or volcanic eruptions.

Throughout Earth's history, there have been several ice ages and global climate shifts, the most notable of which are ice ages.

Natural disasters occur frequently in our lives. Take earthquakes, for example.

Earth's climate has always been in a state of flux. Ever since our ancestors split from the primate evolutionary tree millions of years ago, the planet has faced dramatic swings between wet and dry periods, as well as long periods of freezing and melting glaciers. Clearly, early humans were able to survive these changes, and our very existence attests to their success. But a growing number of scientists believe that major climate changes may have also shaped some of humanity's defining characteristics.

Have you ever wondered? Earth originally had no humans, but where did we come from? When did the first man and woman emerge?

In another remarkable year for science, astronomers unveiled new discoveries about the universe, biologists painted a clearer picture of life on our planet, and paleontologists painted a richer picture of the dinosaurs that roamed Earth millions of years ago.
