The basic evidence for global warming, that it is really happening, is that worldwide instrument measurements show that the world is warming and is continuing to warm. In fact, the last ten years were the warmest decade since instrumental records began in 1850, and the year 2010 was the warmest on record, slightly aboive the record set in 1998 and again in 2005, although because the temperature was only marginally higher, climate scientists regard the as the three equal hottest years globally.
It is difficult to find evidence to refute the instrument measurements. The one serious doubt was based on the urban effect, in which instruments located in originally rural areas gradually become surrounded by urban development, resulting in localised higher temperatures. It was suggested that climate scientists had not properly adjusted for this effect where present, but independent scientists have since confirmed that appropriate adjustments have been made in the climate studies, and confirm that global warming really is happening.
The evidence for global warming are the temperature records collected over the past century. These clearly show global temperature has increased, and dramatically so in the past 30 years.
There isn't any convincing evidence against global warming. There is paltry (a little bit) of evidence to suggest not ALL current warming can be attributed to human activity, but for the most part the evidence we have gathered so far implicates the human consumption of fossil fuels as the primary cause of current global warming.
If one focuses one's attention on a few specific areas of the globe rather than the globe in its entirety, one can build a flimsy case that global warming is not actually occurring. Some of those who argue there is no global warming pick one recent abnormally warm year, and draw a line from it through the coldest parts of more recent years in an effort to suggest temperature is declining, rather than using the standard five or ten year running average indicative of actual climate trend.

Do meteorologists believe in global warming and its impact on weather patterns?
Yes, the majority of meteorologists believe in global warming and its impact on weather patterns. They use scientific evidence and data to support this belief.
How is Global Warming a Scam?
The science of global warming could be a scam if someone had anything to gain by it. Yet scientists resisted the idea that they should be concerned about the possibility for almost a century after the possibility of anthropogenic global warming was first identified. No scientist has anything to gain by creating a hoax. In fact, any evidence that a research scientist has engaged in a scam would be career-destroying.
Is the government hiding global warming from citizens?
It is not possible for the government to be hiding global warming from citizens. However, it can be said that the government is not creating enough awareness campaigns which will prevent global warming.
Why does global warming decrease temperatures?
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
What percentage of climatologists believe in global warming?
Approximately 97 of climatologists believe in global warming.
What is two pieces of evidence that English is the global?
global warming?
Is global warming warming the greatest danger to brown bears?
No, not at all. There is no evidence that the global warming is affecting brown bears.
What evidence is there that global warming is a myth?
There is no evidence that global warming is a myth. There has certainly been a lot of misinformation on the subject, often from vested interests, but the clear consensus of climate scientists is that global warming is real and that human activities are substantially the cause of global warming since the Industrial Revolution.
Why does global warming affect the migration pattern of birds?
There is no evidence that "global warming" is causing birds to migrate differently.
Would polar bears in Mexico be evidence for global warming?
No, that would probably be evidence for global cooling.
What was John Browne's position on global warming?
On May 19, 1997, in a speech at Stanford University, Browne declared that evidence suggested that global warming could be real. He argued that evidence that burning of fossil fuels was contributing to global warming
What pressure groups are critical of the evidence of global warming?
Extremely conservative groups tend to be more critical of the evidence of global warming. This has more to do ideology than idiocy, even though over 97% of scientists acknowledge the existence of of global warming.
Who are the scientists working with global warming?
The work of 15 climate scientists is helping to educate the public about the overwhelming scientific evidence for human-caused global warming.
Where on earth is there evidence Global Warming?
At the poles we see that the icecaps seen to be melting.
How long have people been fighting about global warming?
The debate over global warming began in the late 19th century, but intensified in the late 20th century as scientific evidence grew. The issue has become more contentious in recent years due to conflicting opinions and political interests.
How did the deployment of nuclear weapons effect global warming?
I am pretty sure the deployment of nuclear weapons on Hiroshima and Nagasaki did not affect global warming. There is no evidence to suggest that the deployment of nuclear weapons in the second World War affected global warming in any way.
Do you realize global warming is a myth?
The overwhelming consensus among climate scientists is that global warming is real and primarily caused by human activities, such as the burning of fossil fuels. The evidence for climate change is supported by data from temperature records, melting ice caps, and shifting weather patterns. It is important to rely on scientific evidence and expert consensus when evaluating issues like global warming.
