Is global cooling real

Answer 1

The evidence for recent Global Warming is abundant and is generally accepted almost everywhere in the world outside the USA. How much of the recent Global Warming is caused by human action is slightly less certain, but most people (and in particular most scientists) accept that the major contribution is from overuse of carbon fuels.

• The facts speak for themselves. The average global temperature is rising and has been doing so since the Industrial Revolution. The years 1998, 2005 and 2010 are regarded as the equal warmest years on record. The past decade was the warmest since instrumental measurements began in 1850, and the ten warmest years since 1850 have now all occurred since 1998.

• Global warming (or more accurately global climate change) is occurring and presents a danger to the Earth. Science confirms it, observations of temperature, ice cap melting, wind patterns of ocean currents, the changing distribution of fish and wildlife, climatic anomalies all are consistent with climate model predictions. Almost every climate scientist agrees with the models, the math and the evidence, as do the majority of scientists overall regardless of their discipline.

• No known natural cycle accounts for the continued measured increase in global temperature.

• No known solar cycles map to earth climate cycles. The tiny measured variations in solar output have no correlation to measured rapid changes in earth's climate.

• All earth's volcanoes and natural sources emit about 300 million tons of CO2 per year. The earth appears able to absorb this level of CO2 (a heat trapping gas) without significant environmental consequence, as carbon dioxide levels have not changed substantially in the 800,000 years preceding our industrial revolution. Humans, however, now pump 100 times this much CO2 into the atmosphere each year--now more than 30 billion tons. Careful and critical scientific inquiry has lead us to reject the claim this excess carbon has no environmental impact.

Here are some contrary opinions.

• The climate has changed in past years, but it has been both hotter than this and colder. A few people insist that Global Warming is a hoax. The earth can't really be affected by people although it a good thing to stop pollution and clean the earth.

• Cold and warm weather is determined by solar activity, not people.

• Global warming stopped when the Earth started cooling off years ago. In school they always show about how its melting our ice when yet the ice has been melting since before man had machines that pollute the Earth.

• Global warming is a natural phenomenon.

• There's no proof, but keep 'saving the planet' because the CO2 emissions are rising and global warming could exist in the near future.

• The greenhouse effect is a vital part of nature. Without some trapping the planet would be a very cold dead place. What we ask is if man has any part in the current warming that is occurring. A political answer is that no one knows, but it is not likely that we play much, if any role. The warmest year on record occurred in 2010. If man's ever increasing production of CO2 were causing warming, we might expect to see a consistent trend towards warmer temps. The concept of global warming being a man made event is a fear issue. Some people feel the need to create fear to cause people to change their life styles.

What you are asking is, if man has any part in the current global warming and climate change. The answer is unequivocally YES. The warmest year on record occurred in 2010. At present global warming, NASA reports 40% of polar caps have disappeared. This is causing torrential rains, snowstorm, droughts, forest fires, soil erosion, sea level rise. Permafrost is thawing, releasing methane, a greenhouse gas 20 times more potent than CO2. Any measures mankind has to stop CO2 emissions to reverse this catastrophe may be too late.

Answer 2

Imagine this: The sun's rays enter the earth's atmosphere, warm us up, and bounce back out leaving a little residual heat so we don't begin another ice age. Our atmosphere is primarily nitrogen, oxygen, and a little bit of carbon dioxide. When all our cars and planes buzz around they emit greenhouse gases (from burning fossil fuels). The greenhouse gases trap heat. The sun's rays come in, heat us up, but can't bounce back out as easily as before because the greenhouse gas molecules envelope the earth like a heavy blanket and the heat can't radiate as well. This results in a build up of excess heat. There's global warming for you.

Answer 3

Global warming has been measured. It is difficult to argue with a thermometer, though some folks insist the thermometer record is distorted by the "urban island" heat effect. Cities, with all their concrete, asphalt, higher concentrations of CO2, automobiles, etc. tend to be warmer than the surrounding countryside. Satellite measurements and records omitting urban areas both show a general rapid increase in temperature.

So the warming is both real and obvious. The next question would be, is the warming largely the result of human activity? Humans pump 30 billion tons of CO2 into the atmosphere each year. This is about 100 times what all earth's volcanoes combined emit (per the USGS).

Numerous scientific organizations around the world, tasked with understanding climate change, have created models which clearly implicate human activity as the primary cause for current climate change. These include the Geophysical Fluid Dynamics Laboratory model run by NOAA (the US National Oceanic and Atmospheric Administration), the UK's Hadley Centre Coupled Model, and the Educational Global Climate Model developed by the Goddard Institute for Space Studies as a joint project between Columbia University and NASA.

Answer 4

well if global warming is a hoax then i guess global cooling is too.

both global warming and cooling are just natural cycles of the Earth which people have turned into something more than they actually are.

i have never heard of it but i know global warming is real so if there's global warming there isn't global cooling because they are 2 different things

The recent and sustained global warming period is now known to have been caused by the positive Pacific Decadal Oscillation (PDO), where the Pacific waters warm up for around 25-30 years. We are now in a negative PDO, so there is expected to be a sustained cooling trend for the next 25 years or so.

Simultaeneously, the sunspots have decreased and may cease around 2015 leading the earth into what is called a solar "minimum" similar to the Maunder or Dalton minimum. If this happens, then another cooling trend may become active. Historically, this has accounted for a 0.5 degree F drop per year in the earth's temperature for each year of delayed sunspot activitly. We will have to wait and see how much it really drops (Cycle 24 was delayed aboput three years).

A drop in sunspots is associated with an increase in solar gamma rays hitting the upper atmosphere and an increase in cloud formation, yet another cooling trend. It is uncertain at this time whether this can even be measured.

We are also now in the proper planetary orbital orientation which favors a cooling if not an actual return of an ice age.

Please understand that the global warming effects of CO2 in the prescence of such large amounts of water vapor, diminishes to a small fraction of a degree, once pass

100 ppm.

So, the next several years will tell which trends, warming or cooling, will prevail.

Answer 5

Global warming is certainly real. The year 2010 had the warmest global average temperature on record, fractionally warmer than 2005 and 1998, but as the difference is slight, the three years are regarded as the equal hottest. The past decade was the warmest since instrumental measurement began in 1850, and the ten warmest years since 1850 have now all occurred since 1998.

It is also known that the temperature rise that the world has experienced is consistent with the rise in atmospheric carbon dioxide levels, from the normal range of 260-280 parts per million (ppm) to 380 ppm. Scientists say that because carbon dioxide is a greenhouse gas, it is this increase that has caused average global temperatures to rise. So the question is whether this increase in atmospheric carbon dioxide and the resultant temperature rise are caused by human activity, and are therefore anthropogenic.

Scientists have been able to use isotope comparisons for C12, C13 and C14 ratios, to prove that the increase from 260-280 ppm to the present 380 ppm of atmospheric carbon dioxide is entirely due to human activities. This joins the dots and tells us that anthropogenic global warming is real.

Answer 6

Yes, global warming is real. NASA and NOAA both have research programs that demonstrate the earth is warming faster than for which any natural phenomenon can account.

Climate models by these and other agencies effectively demonstrate the reason for the current rapid rise in earth's temperature is due primarily to the increase of carbon dioxide gas, from the chemical oxidation/reduction of fossil fuel (coal and oil). Human beings currently release more than 30 billion tons of this gas into the atmosphere each year.

Answer 7

Many global scientists who are cognizant with the facts believe it is real, many others do not.

Answer:

In a poll taken by Doran and Kendall Zimmerman in 2009, of scientists in different fields, 97% of those who published at least half of their peer-reviewed research in the climate field agreed that human activity was significant in changing global temperature.

Anderegg et al. similarly found in 2010 polling that 97% of actively publishing climate scientists went along with the international panels' consensus on global warming.

So there is no doubt that an overwhelming consensus of those scientists cognizant with the facts believe that global warming is real and is caused primarily by human activity.

As to the extent of global warming, the year 2010 had the warmest global average temperature on record, fractionally warmer than 2005 and 1998, but as the difference is slight, the three years are regarded as the equal hottest. The past decade was the warmest since instrumental measurement began in 1850, and the ten warmest years since 1850 have now all occurred since 1998.

Answer 8

Global cooling is not currently happening. Overall, the Earth's climate has been warming due to increased levels of greenhouse gases in the atmosphere. While there are natural climate fluctuations, the long-term trend is one of warming, not cooling.
