Global Warming Interesting FACTS ?

Question

What are some interesting facts about global warming? Person with the most facts (and they have to be real)gets BEST ANSWER!!!

Answer 1

People still denying global warming? I hope you guys are joking and if you’re not maybe you should try picking up a book and actually reading it - or here’s an idea - open your eyes?

1. Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.

2. The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.

3. The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.

4. Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss.

5. Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later.

6. Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise.

7. An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts.

Answer 2

One interesting FACT is that the earth has gone through many global warming periods, just like it has gone through many ice ages....

1. "Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies."

Even according to Nasa, the increase in temperature ranges from 0.4 to 0.6 Celsius.

2. "The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850."

Umm, the rate of warming is decreasing.  In fact, January 2007-January 2008 the temperature drop was close to 0.3 Celsius.

"3. The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004."

They studied 4-5 measly years.  Let's look at the long term temperature graphs, dating back about 1,000 years.  Temperatures are still cooler than the MWP.

"4. Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss."

It is believed that the Arctic was ice free during the MWP.  Nothing the planet hasn't seen before.

"5. Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later."

Glacial retreat is a very common thing when the planet warms up.  It has happened hundreds of times before and will happen hundreds of times more (conservative guess, will probably happen thousands of times more).

"6. Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise."

They rebounded with ease after the warming period in the early 30's-40's.  They will rebound again.

"7. An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts."

The extreme weather events scenario should never be considered,  They didn't develop a system to categorize hurricanes until 1971 (Saffir-Simpson Hurricane Scale).  They can look back for a few decades before that and try to categorize the strength of a hurricane, but it is like trying to hit a dart board from 50 yards away.  Wildfires have been a part of the world long before humans came into existence.  We observe more of them, hence we think they are more.  Heat waves?  We've had more cold spells in summer during the past 3 years than heat waves.  

Global warming is based on perception.  You hear that it is warmer, so you will "notice" (think) that it is warmer.  The charts are foolish because they are showing a warming trend after an ice age (The Little Ice Age).  That is completely normal.  They can only guess what the temperatures were before they started keeping the temperature charts in the 1860's.  Even then, they would check their mercury thermometers at 3 points of time throughout the day.  Sunrise, 2 pm (generally accepted as the hottest point of the day), and midnight, for example.  Anyone who pays attention to the temperatures knows that this is ineffective.  It could be hotter at 5 pm than at 2pm and it may cool off before the next temperature check.  So they never accurately recorded that high temperature.  Look at the highs and lows in your area on a weather site.  The record highs and lows don't go beyond the 1960's.  That is when temperature monitoring became more accurate, but we were in the middle of a cooling period.  So it makes perfect sense that we will warm up after cooling.  If we don't warm up, we are heading into an ice age.

Answer 6

i've got too many facts that even i forgot. i believe everyone exept the people who dont believe in them.

Answer 7

There is currently no evidence that man has made any significant contribution to climate change.

Some interesting facts.

1. During most of the past 2,000 years, the temp has been about the same or higher. Currently, we are barely over the average for the last 2,000 years.

2. During the medieval warm period (820 – 1040 AD), Greenland supported farming. Those areas previously farmed are now covered in glaciers. Obviously the melting and reformation of glaciers is a cyclical occurrence.

3. The earth experienced a little ice age which ended around the late 1860's or so. This is about the time man started recording temperatures. This would be like measuring a lake depth after a severe drought, then worrying about it flooding as it rose to normal levels.

4. The earth has been warming for the last 18,000 years, since the last major glacier time period. During this time frame, the glaciers have been melting at a fairly consistent rate. Also, for most of the last 1 billion years, the earth had NO glaciers or ice coverage.

5. The AGW theory states that CO2 is the primary driver of temperature. They arrived at this idea because they did not know of anything else which could cause it. But during the 70's and during the current decade, temperatures dropped while CO2 continued to rise. This means that natural occurrences are driving temp, not CO2.

6. The Pacific Decadal Oscillation and sun spots provides a much better correlation to earths' temperature than CO2 levels ever have.

7. Polar Bears are experiencing a population boom. Coke sales in the arctics are through the roof. Polar Bears have been around for thousands of years, and remember, we are only at the average for the last 2,000 years. They lived through all the previously warmer climates. The original picture of 2 bears on a floating ice block was a complete scam. The photographer explained that the bears were in no danger and close to shore. The picture was lifted from a public PC by another passenger and sent around the world.

8. Many glaciers are expanding. Even Antarctica is growing on 98% of is land mass. Only 2% is melting.

9. There is no consensus on AGW. This was a lie that has been propagated by the media.

10. Yes we emit CO2 into the atmosphere and it is a greenhouse gas, but, we only contribute about .28% of all the greenhouse effect. Water vapor makes up about 95% of the greenhouse effect. CO2 and other trace gases round out the greenhouse gases at about 5% for all of them. Of that 5%, only 3% is CO2, and most of that is natural. Again, our contribution to the greenhouse effect is a paltry .28%

11. The spread of disease is not attributed mainly to temperature. If this were the case, Florida would be a giant festering disease ridden cesspool. Economic standing is the primary determining factor in the spread of disease. Poor cultures can not fight the disease or eradicate the pests like more successful nations.

12. Natural climate disasters (hurricanes, cyclones, etc) have never been scientifically linked to global warming (whether natural or man made).

Answer 8

To add to MikeB's comments:

"4. Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss."

The current ice levels are higher than last year, and the current melting of the ice in the arctic is attributed to unusually warm ocean currents, not air temperature. The reason for the warm current is not fully known and yes the ice has retreated many times before naturally. Plus this is occuring during a cooling phase.

"5. Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later."

During the Holence Optimum people lived above 2000m in the alps where there are now galciers, so this is not unusual and is a natural process, also retreat of glaciers is more linked to changes in predominant wind direction and precipitation and the response to reduced snow fall can takes years to be noticed given the slow response. also many glaciers such as the Fox and Franz Josphef glaciers are growing (whilst the nearby shrinking Tasman glaceir is often referred to as an example of global warming, its only 30km from 2 that are growing which are often not mentioned)

"6. Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise."

Studies of coral have shown they actually survived fine during previous warm periods and infact grew faster based on calcification rates, it is believed this is caused by increased metabolism of coral and increased photosynthesis of their symbiant algae which strengthens the coral to effects like reduced ph of sea water.

"7. An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts."

No study has yet shown emperical data that proves the warming of the last 50 years has increased extreme weather, some studies show the opposite which is inline with meteological principles such as reduced temperature gradient.

Answer 9

The one that most people don't know. and that is the fact that CO2 is not the only gas that causes it and is by far not the worst. Methane CFC and FC gas are magnitudes worse than CO2. And here is some good news for a change:

Answer 10

one fact is that global warming is fake

another is that it is as real as Santa Claus and if you want to get down to it the warming of the earth is natural like the ice age melting

also the hottest years recorded were the 1930 when global cooling was going around. And recently the temperature of the earth is going down ever so slightly but not enough for people to blab about global cooling.

Answer 11

Re Grovesmuk's answer to Redshifts answer on point 6.

"6. Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise."

"Studies of coral have shown they actually survived fine during previous warm periods and infact grew faster based on calcification rates, it is believed this is caused by increased metabolism of coral and increased photosynthesis of their symbiant algae which strengthens the coral to effects like reduced ph of sea water."

What studies, anyone who is an expert in coral reefs would know they are short lived (in geologic terms) they die off regularly the Great Barrier Reef for instance is only 6-8 thousand years old, Reefs are very sensitive to climate change in either direction. And if talking about calcification it should be made clear that warming causes increased acidification in the oceans as they absorb more co2, this is being observed at the moment, and it leads to life forms that use calcification  to be unable to produce hard shells, in past natural warming events such creatures have become extinct or shrunk to tiny numbers.
