The planet is heating up and fast

Glaciers are melting fast, sea levels are rising, cloud forests are dying, and wildlife is struggling to keep march. It crystal clear that humans have caused most of the past century’s warming by releasing heat trapping gases as we power our modern lives. known as greenhouse gases, their levels are higher now than at any time.

We call it global warming, but it is causing a many series of changes to the Earth’s climate, or long-term weather style, that changes from place to another. While many people think of global warming and climate change as synonyms, scientists use “climate change” when describing the complex transfer now affecting our planet’s weather and climate systems in part because some areas actually get cooler in the short term.

How can greenhouse effect our planet?

The “greenhouse effect” is the heating that happens when specific gases in Earth’s atmosphere trap warmth. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse, that’s why it’s called that.

Sunlight shines onto the Earth’s surface, where the energy is absorbed and then clave back into the atmosphere as heat. In the atmosphere, greenhouse gas molecules trap some of the heat, and the rest escapes into space. The more greenhouse gases focused in the atmosphere; the more heat gets locked up in the molecules.

Scientists have known about the greenhouse effect since 1824.
This natural greenhouse effect is keeping the Earth’s climate endurable. Without it, the Earth’s surface would be an average of about 60 degrees Fahrenheit.

In 1895, the Swedish chemist Svante Arrhenius discovered that humans could increase the greenhouse effect by making carbon dioxide, a greenhouse gas.

Levels of greenhouse gases have gone up and down over the Earth’s history, but they had been fairly constant for the past few thousand years. Global average temperatures had also stayed fairly constant over that time, until the past 150 years.
Through the burning of fossil fuels and other activities that have emitted large amounts of greenhouse gases, especially over the past few decades.
Scientists warn: humans are now boosting the greenhouse effect and warming Earth significantly, and in ways that promise many effects.

Why is it so important?

⦁ The fast rise in greenhouse gases is a problem because it’s changing the climate faster than some living things can adapt to. Also, a new and more unpredictable climate poses unique challenges to all life.

⦁ In the past, Earth’s climate has regularly shifted between temperatures like those we see today and temperatures cold enough to cover much of North America and Europe with ice.
The difference between average global temperatures today and during those ice ages is only about 9 degrees Fahrenheit, and the swings have tended to happen slowly, over hundreds of thousands of years.
But with concentricity of greenhouse gases rising, Earth’s remaining ice sheets such as Greenland and Antarctica are starting to melt too. That extra water could raise sea levels significantly, and quickly.
By 2050, sea levels are predicted to rise between one and 2.3 feet as glaciers melt.

⦁ And by mercury rising, the climate can change in unexpected ways. In addition to sea levels rising, weather can become more extreme.
This means more intense major storms, more rain followed by longer and drier droughts.
Which means a challenge for growing crops, changes in the ranges in which plants and animals can live, and loss of water supplies that have historically come from glaciers.

At last, Global warming is not a joke anymore we have to take it seriously because it’s threatening our planet’s future!
