Holocene Era - 🧠ANSWER ✔✔The Holocene Era began approximately
11,700 years ago.
Agricultural Revolution - 🧠ANSWER ✔✔The Agricultural Revolution was the
shift from hunter-gatherer lifestyles to settled agriculture.
Industrial Revolution - 🧠ANSWER ✔✔The Industrial Revolution began in
the mid-1700s and marked a significant increase in human impact on the
environment through the burning of fossil fuels and the expansion of
industrial activities.
, Great Acceleration - 🧠ANSWER ✔✔The Great Acceleration refers to the
period after World War II (mid-20th century) when human population,
economic activity, and resource consumption increased dramatically.
Anthropocene - 🧠ANSWER ✔✔Climate scientists call the current period the
Anthropocene because human activities have become the dominant
influence on Earth's climate and environment.
Evidence of Human Activity in Global Warming - 🧠ANSWER ✔✔Evidence
includes the correlation between rising greenhouse gas concentrations and
global temperature increases, the analysis of isotopic ratios in the
atmosphere, and climate models demonstrating the significant impact of
human activities on climate change.
Key Greenhouse Gasses - 🧠ANSWER ✔✔Key greenhouse gasses include
carbon dioxide, methane, nitrous oxide, and fluorinated gases.
Greenhouse Effect - 🧠ANSWER ✔✔The greenhouse effect is the process
by which certain gases in the atmosphere trap heat from the sun, warming
the Earth's surface.
Global Warming Scenarios - 🧠ANSWER ✔✔The most likely scenario is
continued warming, with potential increases of 2-4 degrees Celsius above
