  4. 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; Modeled and Observed Global Average Temperatures 16

  5. There are three fundamental ways to change the energy balance of the Earth: 1) by changing the incoming solar energy; 2) by changing the fraction of solar energy that is reflected; and 3) by altering the energy that returns to space from the Earth.

  6. Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all...

  7. 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 ...
