<onlyinclude>There is a significant scientific '''consensus about global warming'''; specifically that humans are causing the widespread [[global warming|warming]] on the Earth.

The importance of this consensus is often underestimated by the public. This is due in part to the spreading of misinformation by [[climate change denier]]s, as well as a misunderstanding of how climate scientists came to these conclusions.

==Reasons for consensus==
There are many reasons that explain why the majority of the scientific community agrees on humanity's effect on [[climate change]]. Many of which are covered on this website:

#[[Anthropogenic carbon emissions]] have increased drastically in the past century, adding an imbalance to the [[natural carbon cycle]].
#[[Carbon dioxide]] is a [[greenhouse gas]], therefore contributing to the [[greenhouse effect]]. Along with the emissions of other greenhouse gases, it is causing a warming effect that has been measured in great detail.<ref>NASA. (Accessed May 24, 2016). ''Global Temperature'' [Online], Available: http://climate.nasa.gov/vital-signs/global-temperature/</ref>
#This warming effect causes measurable effects: [[Rising sea level]]s are already noticeable as would be expected of a warming world, [[heat wave]]s are more prominent, [[Arctic sea ice]] is melting, [[glacier]]s are retreating, [[ocean acidification|the oceans are acidifying]], among others.

When substantial evidence piles up in favor of a hypothesis, it becomes increasingly difficult to outright dismiss it. It also becomes much easier to take a stand in favor of the hypothesis. This is the case for human-induced global warming, as scientists can recognize as objectively as possible that global warming is in fact being caused by humans. It isn't just increasing temperatures that scientists can agree on, as the following table shows the [[likelihood]] of various phenomena occurring into the future.

| Increases in intense tropical cycle activity || Low confidence || More likely than not (in the Western North Pacific and North Atlantic)
