It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”
You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible (看不見的) blanket.
Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.
Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.

Cancun is a seaside town in Mexico, where most tourists come here to enjoy the beach, water sports and night life. In fact, it is so modern and Americanized that you might think you were in southern California or Florida.
But just a short two-hour hike from the town lie the ruins of the city of Chichen-Itza, one of the capitals of the lost Maya（瑪雅）civilization. The center of the ruins of this city is the pyramid of El Castillo. The ancient Mayan religious people climbed this pyramid during festival to honor the Sun god. Tourists today climb it to view the architectural achievements of Chichen-Itza and to prove their fearlessness of heights and steep （陡峭的）climbs. There is a sign in Spanish, admonishing visitors “It’s dangerous to go up.” I gladly ignored it and started my climb.
The climbing was tough. The steps were higher than one might normally take., but the climb was not fearful at all. From the top of the pyramid, I had a wonderful view of the ruins of this Mayan city. What was most striking to me was that just beyond the ruins of splendid structures, gardens, temples and what looks like a modern sports stadium, you could only see forests for miles and miles. It was almost as if some race had mysteriously come out of nowhere, built it up and then suddenly disappeared from the planet, leaving only stones in its space.
The only remains on the top of the pyramid were the Temple of Kukulcan. During the festivals to worship the Sun god, only the high ranks would have the right to enter this temple.
After shooting a few pictures, I realized it was time to go down. Only then did I discover that what people fear about the climb is not the trip going up, but the way going down. I saw a few brave souls who were walking down as if they were in their own house. Looking down at the steepness of the pyramid, I desperately feared this great height. My first desire was to joke with a few people, “Where is the elevator（電梯）?” I figured that a civilization that was this advanced would have had the foresight(預見) to construct an elevator. Lacking such modern equipment, I had to use the chain provided by the Mexican tourist authorities and climb down on all fours.
My climb was complete eventually. I quickly got on the bus back to my comfortable hotel. Leaving the ruined city, I was still wondering what possibly happened long ago. But a few hours later, I was back in the modern world drinking cocktails on the beach, bathing in the sunshine before boarding the plane and waiting for my trip back home to the US, where all the modern things such as elevators are available!
