How does this heat the planet, and what does this mean for climate change? – Technology News, Prisons Post – Ohio News Time

You may recall that an elementary school science teacher explained that power cannot be produced or destroyed. That is the basic nature of the universe.

But power can change. When the sun’s rays reach the earth, they are transformed into molecules that feel warm. At the same time, the Earth and its atmosphere return to space. The balance between incoming and outgoing energy is known as the “energy balance” of the earth.

Our climate depends on these energy flows. The planet warms up when its energy consumption exceeds energy consumption.

This can happen in many ways, for example, when the sea ice, which normally reflects the sun’s rays, disappears and instead the dark sea retains its power. It also occurs when greenhouse gases accumulate in the atmosphere and trap other energy.

A scientist like me has measured the earth’s energy balance. This is an important part of the new UN climate assessment. The Panel on Climate Change was released on August 9, 2021.

It tells us how this energy flows and how the energy balance warms the earth.

Balance solar energy

Almost all the energy of the earth’s climate comes from the sun. Only a small part of it rises from the earth.

On average, the planet receives 340.4 watts of light per square meter. All sunlight falls on the side of the day, and at noon the local numbers are very large.

Then 340.4 watts / square meter

• 99.9 watts reflected in the clouds, dust, snow and earth.
• The remaining 240.5 watts are about a quarter of the atmosphere, and the rest are absorbed by the planet. This radiation is converted into thermal energy in the earth’s system.

Almost all of the baptized power is related to the power released into the universe. However, the residue is now accumulating as the temperature rises. The rest increased by less than 0.6 watts per square meter from 2006 to 0.79 at the end of the last century. It may seem like a few, but the knees are bent.

The atmosphere emits a lot of energy and releases it into the moon into space, returning it to the surface of the planet. In fact, the surface of the earth receives about twice as much radiation as the atmosphere. This is mainly because the sun only warms up during the day and the warm weather is open 24 hours a day, 7 days a week.

Together, solar and atmospheric energy reaches 504 watts per square meter. The earth’s surface generates 79 percent. The remaining surface energy evaporates water and heats the air, sea and land.

The remaining greenhouse gas between the incoming sunlight and the infrared expense is like carbon dioxide in the air. These gases transmit sunlight, but infrared rays are vague – they emit a lot of infrared light.

Ground temperature should rise accordingly until the balance between incoming and outgoing radiation is restored.

What does this mean for global warming?

Increase the amount of carbon dioxide by 3.7 watts per square meter. Imagine an old unauthorized night light sitting every 3 feet around the world every year and shining forever.

With current emissions, greenhouse gas levels will double from pre-industrial levels to the middle of the century.

Climate scientists estimate that this will increase global warming, which will warm the earth’s temperature to about 5 degrees Fahrenheit[3 ° C]. To prevent this, it is important to replace fossil fuels, which are the main source of greenhouse gases. Emissions, along with other forms of energy.

Earth’s energy balance is at the heart of the new IPCC climate assessment. Written by hundreds of scientists reviewing recent research. As we all know, change can help everyone to make better choices in weather.
