This class describes the science of global warming and the forecast for humans’ impact on Earth’s climate. Intended for an audience without much scientific background but a healthy sense of curiosity, the class brings together insights and perspectives from physics, chemistry, biology, earth and atmospheric sciences, and even some economics ...
To understand climate change, it is crucial to use a scientific definition of climate, understand the difference between weather and climate, and to study changes in the state of the climate that persist for an extended period. It is also important to understand how the natural factors such as latitude, altitude, reflectivity of
6 Ιουν 2018 · The exact steps of the scientific method can vary by discipline, but since we have only one Earth (and no “test” Earth), climate scientists follow a few general guidelines to better understand carbon dioxide levels, sea level rise, global temperature and more.
In 2023, the Intergovernmental Panel on Climate Change (IPCC) concluded that “human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850-1900 in 2011-2020.” 15
Climate change and global warming are well up on the current political agenda. There are urgent questions everyone is asking: are human activities altering the climate? Is global warming a reality? How big are the changes likely to be? Will there be more serious disasters; will they be more frequent?
