Final answer:
Global warming refers to the observed increase in the Earth's average surface temperature due to heightened levels of greenhouse gases from human activities.
Step-by-step explanation:
What is Global Warming?
Global warming is the term used to describe the recent rise in the Earth's average surface temperature, which is primarily attributed to an increase in greenhouse gases caused by human actions. Scientists indicate that the Earth's temperature has risen by almost 1°C (about 1.3°F) over the past century. This change has significant ecological consequences, affecting various species and habitats, and is closely tied with the broader phenomenon of climate change, encompassing shifts in weather patterns, storm activity, and sea levels.
According to peer-reviewed studies, 97-98% of the most published climate researchers agree that humans are a primary cause of global warming. The increase in temperature is contributing to social disruptions due to the harmful impacts on natural ecosystems and human societies, such as rising sea levels, loss of Arctic sea ice, and extreme weather events. It is evident that without significant efforts to reduce carbon emissions and mitigate the effects, the situation will likely become more dire.
