: [[Climate Change|climate change]] caused by '''global warming''' can cause [[Habitat Destruction|habitat destruction]] due to changes in weather patterns in many different [[ecosystem]]s possibly causing drought, flooding, temperature rises or temperature falls depending on the location.
: Some [[scientist]]s are investigating ways to slow or reverse '''global warming''' to prevent [[Climate Change|climate change]]. These methods are known as [[geoengineering]] and they are an attempt to control the [[Mean Average|average]] [[temperature]] of the [[Earth]]'s surface.
===Uncertainties about Global Warming===
While the [[Mean Average|average]] [[temperature]] of [[Earth]] seems to be increasing there are some [[uncertainty|uncertainties]] in the [[measurement]]s taken.
*[[Accurate]] [[temperature]] records from [[thermometer]]s only go back around 160 years.
*[[Thermometer]]s that were once in [[rural]] areas are now surrounded by buildings which causes a [[Heat Island Effect|heat island effect]] which makes the readings unreliable as there is another [[variable]] which has affected their [[temperature]] [[reading]]s.
*Old [[thermometer]]s were far less [[accurate]] than modern [[thermometer]]s. Some [[scientist]]s believe this is what caused an apparent halt in '''global warming''' over the last decade and in fact '''global warming''' didn't stop, we just got better [[thermometer]]s.
