First, we have to understand the weather is not climate, the weather is the consequence of the climate. To understand what is happening with our planet, we have to follow the history of the Earth’s climate. The climate of the Earth has a cycle, rate now we are in an ice age. This ice age is not Earth’s first time to see this stage, but over 800,000 years has happened nine times; the only difference was the period the globe was in an ice age.
The position of the planet in our solar system plays a big part in the Earth’s climate. When the globe is tilted closer to the sun, we will receive more heat. The planets circle the sun, so the further away we are, the colder the global temperatures will be. We usually orbit the sun in a circle, every so often the rotation changes and we circle the sun in an oval shape, cooling the globe down. Roughly every 36,000 – 41,000 years, the global climate changes drastically. Every 100,000 years, the Earth breaks away from this cycle. It all has to deal with the perfect position of our planet, allowing the seawater to freeze, covering a lot of the northern and southern poles, this then cools down everything. With scientist data, we know that we are at the end of our global ice age.
Why is the Earth heating up? The sun is stronger than it was 800,000 years ago, yet it only has an impact of .07%. Volcanic eruptions, massive forest fires burning hectares of land play a factor in the warming. The most significant factor to the planetary heating is the greenhouse gases that we humans have produced.
The last warming cycle happened roughly 200,000 years ago. The planet had temperatures that we have not seen in our lifetime. There were no ice caps, and sea levels were higher. The land was covered in lush green plant life, ideal for the animals to survive off. This gave life to many mammals, though it was devastating to many other species that could not adapt to global climate change.
With this data and understanding, there is nothing wrong with the planet. The future of the Earth is following its cycle. What this means for us, though, is uncertain!
