What is greenhouse effect and its importance?
The greenhouse effect refers to the ability of the atmosphere to trap the sun’s heat, increasing the temperature of the planet. When the sun’s energy reaches Earth, the atmosphere absorbs some of it on the way down, and then absorbs more when that energy reflects back off the surface during the day.
What did Svante Arrhenius discover climate change?
In it, Arrhenius concluded that a reduction in the atmospheric CO2 levels to half the then existing ones would result in a drop in the temperature of the planet of between 4 and 5°C, which could lead to a massive cooling like the one that takes place during glaciations.
Why is the greenhouse effect a good thing for life on earth?
Greenhouse gases keep our planet livable by holding onto some of Earth’s heat energy so that it doesn’t all escape into space. This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm.
How is the greenhouse effect essential to life on earth?
What are the positive effects of the greenhouse effect?
The greenhouse effect is a good thing. It warms the planet to its comfortable average of 59 degrees Fahrenheit (15 degrees Celsius) and keeps life on earth, well, livable. Without it the world would be a frozen, uninhabitable place, more like Mars.
What is Svante Arrhenius famous for?
Svante Arrhenius, in full Svante August Arrhenius, (born February 19, 1859, Vik, Sweden—died October 2, 1927, Stockholm), Swedish physicist and physical chemist known for his theory of electrolytic dissociation and his model of the greenhouse effect. In 1903 he was awarded the Nobel Prize for Chemistry.
Did Svante Arrhenius discover the greenhouse effect?
Svante Arrhenius (1859-1927) was a Swedish scientist that was the first to claim in 1896 that fossil fuel combustion may eventually result in enhanced global warming.
