7、planet,or new plans to battle its effects like the one announced by the former US President Barack Obama the other day.But the concept itself isnt new at all in fact,scientists have been exploring questions about climate change for almost 200 years.The idea of “greenhouse gases” goes back to 1824,wh

8、en Joseph Fourier wondered what was regulating the earths temperature.Fourier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a glass lid:As light shines through the glass,the inside gets warmer as the lid traps the heat.

9、As Fouriers ideas spread,it came to be called “ the greenhouse effect”.Scientists continued to study the greenhouse effect.Until a Swedish chemist named Svante Arrhenius came along,scientists understood how global warming actually works.After years of work,Arrhenius determined that the level of carb

10、on dioxide in the atmosphere did in fact have a direct effect on global temperatures.Arrhenius found that CO2,and other gases trap radiation,which warms the atmosphere.Arrhenius was the first to suspect that burning coal could contribute to the greenhouse effect.But Arrhenius welcomed the warming ef

11、fect on the planet.At a lecture later that year,Arrhenius noted that creatures of a warmer earth “might live under a milder sky and in less barren surroundings”.While Arrhenius findings won him the 1903 Nobel Prize in Chemistry,scientists kept debating whether the greenhouse effect was increasing un

12、til 1950,when researchers finally began to find strong data to support it.By the end of the 1950s,American scientists had been sounding the alarm on the long-term consequences of climate change.Climate change research has come a long way since Fourier first described the greenhouse effect.Maybe Arrh

21、s native mosses,these are now under increased threat from three major sources:visiting scientists,increasing number of tourists and global warming.However,it is global warming that is the main driver of the greening of Antarctica.In 2015,more than 38,000 tourists visited the Antarctica.“These touris
