Quizplus · Accepted Answer

The overwhelming scientific evidence supports that the average global temperatures have indeed increased over the past 100 years by about 0.8°C (1.4°F). This trend has been attributed to greenhouse gas emissions caused by human activities such as burning fossil fuels and deforestation, which trap heat in the atmosphere and lead to a warming effect known as the greenhouse effect. This warming trend is causing significant impacts on the environment, including sea level rise, more frequent heatwaves, increasing intensity of storms, and changes in agriculture and ecosystems.
