The general trend in global climate change during the past 50 years has been an increase in global temperatures, with significant impacts on weather patterns, sea levels, and ecosystems.
Global temperatures are likely to increase over the next 50 years if humans continue to operate under the "business as usual" scenario because of the continued emission of greenhouse gases such as carbon dioxide. These gases trap heat in the Earth's atmosphere, leading to a warming effect known as the greenhouse effect.
Pollution produced by humans, such as aerosols and particulate matter, can actually have a cooling effect on the planet by reflecting sunlight back into space. This phenomenon, known as global dimming, can temporarily offset the warming effects of greenhouse gases. However, this cooling effect is not a long-term solution and can have negative consequences for air quality and human health.
The Intergovernmental Panel on Climate Change (IPCC) reviews published scientific literature on climate and produces statements related to trends in climate change and its impacts
