Global warming refers to the idea that the Earth's average temperature could significantly increase to the point where it will have noticeable (and probably detrimental) effects on how people live.
Also known as: climate change
- If humans are at all responsible for global warming (a point currently under debate, as described here), then by definition global warming is a sustainability issue.
- James Hansen, "NASA's top climatologist", has claimed in writing and on TV that the Bush Administration has tried to restrict and suppress discussion of global warming
- Prominent deniers of global warming include Bjorn Lomborg
The following points of debate have pretty much been resolved (see #News for details regarding the answers):
- whether or not the Earth is currently on a general warmining trend – yes
- whether or not this will have significant effects on anyone – yes
- whether or not those effects will be bad – in the short term, yes; beyond that depends on a lot of unknown factors
There continues to be debate on the following points:
- whether or not this trend, if it is real, will continue
- whether or not the warming is being caused by humanity (strong circumstantial evidence that it is)
- Could be caused by random climatic drift
- Could be caused by changes in any of countless variables, e.g. the sun's energy output
- whether it is in humanity's best interest to attempt countermeasures (as opposed to "letting nature take its course")
- what sorts of countermeasures should be taken (e.g. should we try to counteract the warming trend itself, or just be prepared to deal with the changing climate and rising sea levels as they happen?)
There appears to be some considerable political pressure to deny that there is a dangerous warming trend.
Difficulty of Resolution
Part of the problem is that the issue has become heavily politicized, largely because direct countermeasures (attempts to counteract the warming trend) tend to be unpopular amongst those who would need to implement them, and those who would need to implement them are generally large businesses with significant amounts of political clout and ability to drive the discussion in directions favorable to them.
Another part of the problem is that determining whether or not the phenomenon is of genuine concern requires the integration of large amounts of data – over long timespans and a large number of different geographical locations – in order to notice subtle real effects without raising false alarms due to temporary or local effects.
Although the majority of scientists agree that global warming is occurring and is caused by humanity, a few disagree; each of these few generally express one of the following positions:
- The Earth is not warming: surface records seem to show a warming trend, but satellite and weather balloon records do not.
- The Earth is warming but the cause is unknown
- The Earth is warming but mostly due to natural processes
- Global warming is occurring but not as much as feared
Arguments against global warming:
- Global warming is junk science: There are claims that scientists "proving" global warming are purposefully lying and modifying data or at least using questionable analytical methods.
Scientists are divided on the issue: although there are a few dissenters, the scientific consensus agrees that global warming is happening and that it is anthropogenic; see The Scientific Consensus on Climate Change Global warming is self-correcting: possibly, but the corrections may take some time
- At least one group has argued that the Earth is actually cooling:

He suggests that the relatively simple solution of land use management could potentially give us the ability to control the concentration of CO2 in the atmosphere at any level we'd like, and there's no need to stop burning coal and oil."

- 2004-12-03 The Scientific Consensus on Climate Change
- The 2006-10-27 report that the Atlantic current came to a halt for 10 days in 2004 was a severe misrepresentation of what actually happened, as explained here: a new monitoring array is recording more precise data on the current than has previously available, and one of the things it noted was a "very weak" flow during those 10 days in 2004. However, due to the newness of the data set, scientists don't yet know if this is unusual, part of an accelerating trend, or perfectly normal. As yet, it has no known implications for the climate of Britain or Europe.
