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.

What is the reverse change of global warming global Cooling or Global Freezing?

The reverse change of global warming is global cooling, which refers to a decrease in average temperatures worldwide. Global freezing is not a recognized scientific term but can be used colloquially to emphasize extreme cold conditions.


How would glaciers be affected by changes in climate such as global warming and global cooling?

In global warming, the glaciers would melt, then they would flow into the ocean, then they could affect ocean currents, changing the climate, in some areas. And with global cooling, there would be more glaciers, depleting the ocean waters.


Why did scientists think the world was experiencing global cooling between the 1940's and 1970's?

During the mid-20th century, scientists observed that global temperatures were decreasing, which led to concerns about global cooling. This cooling trend was likely influenced by natural climate variability, such as increased aerosol emissions from industrial activities and volcanic eruptions, which can block sunlight and have a cooling effect on the climate. However, as our understanding of climate science improved and more comprehensive data became available, it became clear that the long-term trend is global warming due to human activities.


Which event followed a massive volcanic eruptionand led to the cooling of global temperatures?

The event that followed a massive volcanic eruption and led to the cooling of global temperatures was known as a volcanic winter. The eruption can inject large amounts of ash and sulfur dioxide into the stratosphere, blocking sunlight and causing a temporary cooling effect on Earth's climate.


How many scientists agree that global warming is real?

The overwhelming majority of scientists agree that global warming is real. Multiple studies have shown that around 97 of climate scientists support the consensus that human activities are causing global warming.

What is the opposite of global warming?

The opposite of global warming is global cooling, which refers to a decrease in the Earth's average temperature over an extended period of time.


Is global cooling really happening?

No, definitely not.


What does global cooling do to the earth?

It cools it somewhat. Global cooling occurs after a volcanic eruption when clouds of dust remain in the sky for several days reflecting the sun's rays. This results in a cooling of the atmosphere.


What is worst global warming or global cooling and why?

If global cooling means the gradual cooling into an Ice Age, then that has happened in the past and it has taken thousands of years to happen. The present global warming has all happened far faster, in less than 200 years, and is threatening all life on the planet if we can't stop it. Global warming is by far the more dangerous situation.


What is the possible result of global cooling?

There was a time in the 1970s when scientists though the earth might be approaching a global cooling period. This was quickly proved incorrect. But a possible result of global cooling would be more ice caps, larger glaciers, colder winters, cooler summers etc.


In what century did global cooling end?

Global cooling ended at the end of the 19th century. According to warmists, this is because of the rise of industry which began to emit pollution (carbon dioxide).


Would polar bears in Mexico be evidence for global warming?

No, that would probably be evidence for global cooling.


How will Earth be in 2020?

If Global Warming and Global Cooling can be balanced correctly then the Earth should be a better place

What is the difference between global warming and global cooling?

Global warming is when the global average annual temperature is generally trending upward. Global cooling is when it is trending downward.A:Global warming is happening now. Global warming is not beyond the control of mankind. It is being caused by our dependence on fossil fuels (coal, oil and natural gas) which we are burning to produce electricity.


What are the conditions that can cause global cooling?

Global cooling can be caused by phenomena such as volcanic eruptions, which release large amounts of ash and sulfur dioxide into the atmosphere blocking sunlight. Changes in the Earth's orbit and tilt can also lead to global cooling by reducing the amount of solar radiation reaching the planet. Additionally, a decrease in solar activity, known as a solar minimum, can result in cooler temperatures on Earth.
