If the earth has had periods of warming and cooling for millions of years, why the hypertension on global warm

Question

on global warming today? It seems it's going to occur in any event so why go bust over it?

Answer 1

In Roman's time, the global temperature was coniderably higher than now: in fact, Greenland coasts was colonized and some cultivations realizable!
Of course extra-emission of carbon dioxide increases the natural warming process that we are living today, but it's just a component, not unique guilty.

Answer 2

The thought of global warming, along with the 'shortage of oil' in the world, allows the oil companies to make a 'bomb' from the increased prices that they can bring when they say they're running out. Governments also rake in the cash due to all of this hype and so their country's economy is being improved. The only people that r losing out in this world r the consumers as they r paying for, or the thought of, global warming.
I believe that global warming caused by humans is a bit of a farse and not 100% true, if there is any truth in it. I heard about the earth's magnetic fields change every 700,000 yrs and at this time, the earths seasons f*ck up nd everythin heats up or cools down dependin on the way that they change. I also learned that this hasn't happened for over 700,000 yrs and is likely to happen sometime soon, if this is not already a part of that process.

I'm constantly amazed by the complete level of misinformation given by global warming proponents. "The climate is steadily rising causing glaciers in Antarctica to melt causing sea levels to rise as well as a host of other natural disasters." Just what scientists are saying this. The science says just the opposite. There is no warming in the Antarctic according to the scientists who just released the most recent IPCC report. In fact, NASA satellite temperature measurments shows that Antarctica is getting colder. The ice sheet are getting larger in Antarctica not smaller.

What is so educational about Al Gore's movie? The part where he says that the seas will rise twenty feet by 2100? The IPCC predicts a rise of 18 inches over the next century, so what science did Al Gore use to get to 20 feet?

And where is the evidence that human activity is "accelerating global warming?" The IPCC report show an increase of the earths temperature of 0.6 degrees Celsius over the last century. Historic temperature trends taken from ice core samples show warming rates that a quicker than the current warming at many different times over the past 10,000 years. For example there was a warming period of 2.8 degrees C from 800 to 600 years ago (the medieval warm period) This equates to 1.4 degrees per century. Warming from 2700 to 2600 years ago showed an increase of 2.6 degrees C in just that one century, or the 3 degree C increase in temperature 8600 to 8500 years ago. Thats 3 degrees in one century, as compared to the 0.6 degrees that we saw in the last century.

Going back even longer than the last 10,000 years the earth saw warming of over 8 degrees C at the end of the last ice age (around 18,000 years ago) and 12 degrees C of warming starting 138,000 years ago.

There is nothing extraordinary about the earths current warming trend. Antarctica which contains the majority of the earths ice is actually getting colder. The world is not coming to an end. There's no reason to panic.

Answer 4

If it occurred at its natural rate, we could easily prepare for it. However, the activities of man, primarily in the early years of the industrial revolution, have accelerated it . The current argument is not over global warming but how fast it is accelerating. We can take steps to moderate the effects if we act now. (And this is even in debate) It, hopefully, will only be a pulse on the natural cycle, not an elevation of the level.

Answer 5

Because scientists use charts and graphs to collect and record data and the climate is steadily rising while at the same time causing glaciers in Antactica to melt causing sea levels to rise as well as a host of other natural disasters. A good movie to get is An Inconvient Truth with Al Gore. It is very educational and will answer your question in more depth.

Answer 6

Natural cycles are natural cycles...they reverse on their own and are in homeostasis (changing and variable within limits). The influence of man is not set to reverse (are we suddenly going to stop using fossil fuels and reforest the areas we are deforesting rapidly?) Feedback loops can be set up that intensify reactions.

Answer 7

Mostly media hype. Twenty years ago, they had us going into an ice age. It's been warming at less than one degree a century.

Answer 8

Because our industrial and agricultural society can be damaged enormously by climate change.

This one is unusually fast and unusually powerful. It's definitely not natural.

We can't totally stop it, we can greatly reduce the damage.

Answer 9

Maybe its because if it is being caused by humans it will be the end of the human race.

Answer 10

because as chicken little said "the sky is falling the sky is falling "
