When did global warming start?
There’s no simple answer, because the causes are complicated, and their relative importance has changed over time. Man’s contribution to the warming trend started to become significant about 1900. From approximately 1940 to 1970, our emissions of pollution roughly cancelled out the warming from greenhouse gases, and temperature was just about constant. Since 1970 greenhouse gases have been the most important factor, and the percentage goes up every year. This graph shows you how things have changed over time.

It was a few “skeptics” with crazy theories and little data, that predicted cooling. They were wrong, just as the few “skeptics” today are wrong.
Even so, we are open to be proven wrong, which is why there are pages on why it is not real. Fair is fair. The truth is we just want people to be aware that human activities (as well as natural causes) have the possibility of creating adverse effects in the US, Antarctica, Greenland, and throughout the world. Global warming can also be detrimental to wildlife such as polar bears, creatures like sea turtles, and sea life like coral reefs,not to mention human health, due to the spread of disease. So is global warming a myth or are there facts to support it as a reality of our times? Is there really such a thing as the greenhouse effect? And if so, what is that? Whether you believe global warming is real or not, we invite you to read what we have uncovered on the many pages of this site… and beyond. Remember, knowledge is power.
