Have there been climate changes in the past?

Answer 1

Yes,loads,when you consider the age of the earth!

Answer 2

Yes there have been enormous climate changes on planet Earth over many billions of years. As an example of this, the last ice-age melted away from the British Isles as recently as 12,000 years ago. During that last ice-age, the ice sheet covering Britain is estimated to have been two miles thick.

There has been a very long series of climate changes. In 13th - 14th century London, they used to have Frost Fairs in the middle of the River Thames, which in the winter months froze solid with about a foot of ice - enough to walk on safely and ride horses on etc.

We may be about to go through a mini-climate change soon, certainly over the next fifty or so years and beyond.

Go back far enough in time and most of what we now call the North Sea was probably a tropical rain forest - hard to believe but possibly true, that's why there's oil beneath it under the present day seabed.

During the Roman period of occupation of the Island of Britain, the water table was 200 feet higher than it is today. Most of the coast line of UK is quite different to how it was then. If you visit the Roman fort of Anderida at Pevensey in Sussex, you'll find the remains of a Roman harbour not far from the fort which is now about one or two miles inland from the seashore. In Roman times the sea would have come right up to the fort.

Answer 3

Yes, and they happened a lot more frequently than we first thought.
If you take the examples of inland bodies of saltwater, and the now calcuable releases of carbon into the atmosphere throughout history its very possible to see.

Not only that weather records show massive differences in contries climate change over a much shorter space of time.

David Belamy has recently been struck off a worldwide organisation for pointing this out and somewhat dissmissing the theories associated with global warming.

Religious txts such as the Hindu Vaiders have numerous tales of environmental change, an so to many cultures demise has been accredited with climate change, such as the Myans.

Answer 4

Yes, the earth has gone through periods when it is warmer than it is now and it has also gone through ice ages. As well as gases in the atmosphere climate is determined by a number of variables including the tilt of the earth, sun activity, the amount of cloud cover, the amount of ice at the poles, how much ocean/land there is etc.

Global warming is the first time someone has been responsible for climate change.

Answer 5

Plenty of them. Some believe that there is a climate change going on right now. If you looked at the current weather, you would notice that the deserts have been literally freezing, the opposite of normal, while places that are usually covered with snow by now are only suffering mild cold. These things happen over time. The earth is constantly changing.

Answer 6

I believe so. In the medieval ages, Britain was alot warmer than it is now, and vineyards could grow in southern counties quite naturally. They don't now, but I have noticed an increasing number of palm trees in and around the Home Counties over the past few years, so maybe we are developing a warmer climate where such vegetation can be sustained.

Winters aren't nearly as cold as they were. In Victorian England, 'frost fairs' were held on the Thames in London when it iced over. In Noughties Britain now, the shades of autumn colours are much more vibrant than they ever were before, and summer plants are 'surviving' a lot later into the year.

Answer 7

Yes, there have been several ice ages, and also periods when temperatures were high. The thing that makes the present climate changes worrying is that they are happening rapidly and they haves been induced buy mans industrial activity.

Answer 8

"The climate (from ancient Greek: κλίμα, "clime") is commonly considered to be the weather averaged over a long period of time, typically 30 years. Somewhat more precisely, the concept of "climate" also includes the statistics of the weather — such as the degree of day-to-day or year-to-year variation expected."

Hope this helps!

Answer 9

Hye, person, the climate always changes - that's why it is so hard to figure out past history events as the ice age

Answer 10

Ermmm.....I'm sure there was an ice age once upon a time-Climate change is cyclical throughout history-don't believe all this bollox about global warming from greenhouse gases-if it makes driving to work in blackest December a bit warmer then bring it on!!

Answer 11

yes..Manny thing can and have changed the climate of the earth and it can happen almost "over night" if you take in to ac cont the affects of volcano's or meteors or even massive sol or flairs..
