Is the Arctic "dormant" methane or "awakened", and the sixth mass extinction climax is approaching?
Arctic 'dormant' methane may be 'awakened'
Introduction: About 65 million years ago, the dinosaurs, the biological overlords on the earth, were tragically extinct, so there were a lot of vacancies in the ecological chain of the earth. It stands to reason that mammals should quickly rise to become the new overlords of the earth at this time, but That wasn't the case, as dust and carbon dioxide levels in the air surged after the planetary collision that killed the dinosaurs, and temperatures began to mess up.
For most warm-blooded mammals, this environment is also a very difficult situation, so in fact, during this period, the rapid development of cold-blooded animals that can adapt to various extreme weather, the most representative is the giant Titan The python is the largest snake ever recorded on Earth.
However, as the earth's climate continues to rise, even if cold-blooded animals can dissipate heat, they cannot withstand the sudden rise in high temperatures on the ground. Therefore, 55 million years ago, when cold-blooded animals ruled the earth for less than 10 million years, they also suffered from heat. exploded and died. This is the peak of the earth's high temperature, after which the temperature tends to drop.
At this time, mammals, which have been dormant for thousands of years, began to enter the "historical stage", because they have cultivated strong survivability in the harsh environment for thousands of years. But what we wonder is, what is the reason for the hot explosion of cold-blooded animals? With the development of current technology, it is found that the cause of the surge in the temperature of the earth at that time may be the combustible ice hidden under the Arctic ice. And now this force under the ice seems to be "stupidly moving", which is probably a great "hidden danger" for human safety.
The "monster" under the ice - flammable ice
The scientific name of combustible ice is methane hydrate. This substance is actually ice containing natural gas molecules, that is, ice that can be ignited. This kind of combustible ice is generally found under lakes, permafrost and oceans. Of course all combustibles experience one thing and that is spontaneous combustion.
The most critical source of methane in combustible ice comes from submarine volcanoes. In 2014, due to human activities, the carbon dioxide content in the atmosphere increased sharply by 9.8 billion tons, while the methane content under the Arctic continental shelf of East Siberia at that time was suitable for 143 times of carbon dioxide emissions. The resulting greenhouse impact is considerable.
We all know that most of the energy source on the earth comes from the sun, so our planet can stay warm, and in the process, carbon dioxide is like a one-way mirror of the earth, constantly turning the sun The energy of light is refracted and returned to the ground, and the reflection efficiency of methane is much higher than that of carbon dioxide, so once the methane returns to the surface of the earth's atmosphere, the temperature of the earth as a whole will only continue to rise, and eventually ushered in. It would be terrifyingly "extremely hot".
How long are we from extreme heat?
Extremely hot may not be far away from us over time, but the "dividend" brought by social development has made many people think that things cannot develop so quickly, even scientists at that time felt that the underground was flammable. The ice has always been in a stable state, but in recent years, phenomena from the Arctic have begun to interrupt this period of peaceful stabilization, as methane levels in the Arctic air begin to "climb", and once methane emissions peak, the entire Arctic Continents could be melted.
Conclusion:
Therefore, in order to deal with this phenomenon, various countries and organizations have begun to introduce measures, but climate change will not be changed for the sake of some measures of human beings. If the "extremely hot" tragedy will not happen, it needs to start from now on. Minimize the aftermath of human deterioration of the ecological environment.

Why are there no penguins in the Arctic? 69 penguins were stocked in the Arctic in the 19th century. How are they doing now?
Little kids often ask weird questions like do polar bears hurt penguins? I believe that some friends will be puzzled at first hearing this question. In fact, the answer to this question is extremely simple - because penguins only live in Antarctica.

Tiny Lion Cubs Struggle To Keep Up With Mom
In the heart of the African savannah, life is a constant lesson for young animals. Few scenes are as endearing — or as heartwarming — as tiny lion cubs trying to keep pace with their mother. These little bundles of fur face a world full of challenges, from learning to hunt to avoiding dangers, all while depending on the guidance and protection of their experienced mom. Watching cubs wobble and tumble as they attempt to keep up with their mother reminds us that growing up, even in the wild, is a journey full of struggle, determination, and adorable missteps. The Early Days of Lion Cubs Lion cubs are born blind and helpless, usually in litters of two to six. For the first few weeks, they rely entirely on their mother for warmth, food, and safety. Even after opening their eyes and beginning to explore, the cubs are far from independent. The first months are crucial. Cubs learn social cues, hunting basics, and survival skills simply by watching their mother and the pride. But as anyone who has observed them knows, there’s often a huge gap between observation and action. Tiny cubs often struggle to match their mother’s pace, especially when she moves through long stretches of savannah or leads the family on patrols. A Mother’s Role in the Wild For a lioness, raising cubs is a full-time commitment. She hunts, defends her territory, and teaches her young, all while staying alert to predators such as hyenas, leopards, and even rival lions. The cubs, meanwhile, attempt to mimic her every move — often with clumsy yet charming results. A mother lion’s patience is remarkable; she frequently slows down, nudges them along, or stops to ensure no cub is left behind. These moments, while stressful for the tiny cubs, are vital learning opportunities. Struggling to Keep Up: Why It’s So Hard There are several reasons why tiny lion cubs have trouble keeping pace with their mother: Short Legs, Big Steps: Lion cubs’ legs are tiny and their coordination is limited, making it difficult to cover the same distance as an adult lioness. Curiosity: Cubs are naturally curious. A single butterfly or rustling bush can distract them, leaving mom to pause repeatedly. Energy Levels: Young lions tire quickly. Even with frequent naps, the cubs’ stamina is far lower than their mother’s. Learning Through Play: Play is not just fun; it teaches hunting, balance, and social skills. Running off to pounce on a sibling or chase an insect is all part of their education. Despite these challenges, the cubs’ determination to keep up demonstrates their resilience and growing understanding of the wild world. Lessons in Teamwork and Survival Every cub struggling to keep up is also learning crucial survival skills. The journey across the savannah is more than a test of speed — it’s a lesson in: Coordination: Cubs learn how to move efficiently across different terrains. Patience: They begin to understand the rhythms of adult life and the pace required for survival. Social Skills: Staying with the group teaches cubs how to interact with siblings and the pride, which is essential for their future roles. Observation: By following their mother, cubs study hunting techniques, territorial behavior, and predator awareness. Even the moments when cubs stumble or lag behind are essential for their development. These experiences prepare them for independence, which comes sooner than many might expect. The Cutest Moments in the Wild Anyone who has watched tiny lion cubs knows that their struggles are often irresistibly cute. Video clips from wildlife reserves frequently show cubs toddling along, tumbling over each other, or getting distracted mid-step. Observers often comment that these little stumbles reveal personality, determination, and playfulness, making them one of nature’s most heartwarming spectacles. While their mother is serious and focused, the cubs inject a sense of humor and lightness into life on the savannah. Why This Matters The struggles of lion cubs aren’t just adorable — they’re vital for understanding wildlife behavior. Conservationists and animal behaviorists use these moments to study growth patterns, social structures, and survival strategies in lion populations. These observations also highlight the importance of preserving natural habitats. Cubs must learn in a safe environment to survive; habitat loss, poaching, and climate change make these early struggles even more dangerous. Protecting the African savannah ensures that future generations of lions can experience the same lessons and playful tumbles. The Road to Independence Within a year, these tiny cubs will be more agile, faster, and more confident. By the time they reach two to three years old, males may begin to leave the pride, while females often stay and become caretakers themselves. Every misstep, tumble, and lagging moment is part of the journey toward strength, coordination, and independence. Watching them now gives us a glimpse of the challenges they will overcome, and the survival skills they will carry for life. A Celebration of Motherhood Ultimately, these scenes remind us of the incredible bond between mother and cubs. Her patience, vigilance, and teaching are the foundations of their future. The cubs’ struggles highlight the trials of growing up, while their determination showcases the resilience and beauty of wildlife. For those observing, it’s a powerful lesson in care, guidance, and perseverance, not just in lions but in the natural world as a whole. Final Thoughts Watching tiny lion cubs try to keep up with their mother is both entertaining and enlightening. It’s a story of growth, struggle, and resilience — a reminder that even the fiercest creatures start small, learning step by step. These little lions capture hearts while teaching life lessons: patience, determination, teamwork, and the importance of guidance. As they tumble and waddle across the savannah, they show us that growth is a process, one adorable misstep at a time. For wildlife enthusiasts, animal lovers, and anyone enchanted by nature, these tiny cubs are proof that even in the wild, love, care, and persistence are universal truths.
