Have you noticed that over the past few centuries, the environment has changed quite a bit? Some people argue that it hasn’t changed at all but what about the lakes that are now all dried up? What about the increase in temperature in general? People often confuse climate change for global warming but while they are similar in some sense, they are also very different. Global warming is only when the earth is getting warmer and climate change is when the earth is getting warmer or colder at surprising rates. Last year, it was the hottest on record for the third year in a row. Certain places in the Arctic have risen up to approximately 51 degrees fahrenheit. The Arctic region is known for its cold temperatures and if it has risen up that much in just a few centuries, then what is going to happen to the rest of the world? …show more content…

The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to
