finding out about… the greenhouse effect
Heat from the sun shines onto the Earth. It passes through a blanket of gases in our atmosphere.
Some of the heat energy is reflected back into space. Some of the heat energy gets absorbed by the blanket of gases.
The ‘greenhouse’ gases are essential to life on Earth. Without them heat energy would escape back into space. Earth would be a very chilly place with an average temperature of -18°C !
The greenhouse gases help to keep the temperature of the earth in balance. This process is called the GREENHOUSE EFFECT. The gases work a bit like glass in a greenhouse to trap in warmth. But the earth is getting warmer and warmer. WHY?
As we burn more fossil fuels, for example, the blanket of greenhouse gases becomes thicker. Human activities are creating more greenhouse gases including carbon dioxide, CO2.
More greenhouse gases in the atmosphere mean that more heat energy is absorbed. We call this increase in the temperature of the earth‘global warming’.
Think about ways that you could reduce your carbon footprint and be part of the climate-change solution! Eleven of the last twelve years have been the hottest since records started in 1858.
