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.
Here are some contrary opinions.
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.
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.
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.
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.
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.
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.
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.
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.
No, definitely not.
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.
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.
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.
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).
No, that would probably be evidence for global cooling.
If Global Warming and Global Cooling can be balanced correctly then the Earth should be a better place
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.
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.
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.
