“Climate Change: Science and Impacts Factsheet.” Pub. No. CSS05-19. September 2021 Observed Impacts Physical Systems • Global average temperature was 0.98°C (1.76 °F) higher in 2020 than in the late 1800s.15 • The warmest year on record since records began in 1880 was 2016, with 2020 ranking second.
Climate change science seeks to understand the physical, chemical, biological and geological processes, and the interactions among these processes, that produce climate. The scales of interest range from local to global and from weeks or months to millions of years. Changes in climate, both temporally and spatially,

To understand climate change, it is crucial to use a scientific definition of climate, understand the difference between weather and climate, and 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
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.
A world-renowned expert, Sir John Houghton explores the scientific basis of global warming and the likely impacts of climate change on human society, before addressing the action that could be taken by governments, by industry and by individuals to mitigate the effects.
PART 2: The Science-. Sound is produced when matter. vibrates and like light, travels through a medium in the form of waves. Sound waves are composed of a series of high and low points, much like the crest and trough of an ocean wave. The distance from one wave crest to another is known as a wavelength.
