Global climate change

from class:

General Biology I

Definition

Global climate change encompasses long-term alterations in temperature, precipitation, wind patterns, and other aspects of Earth's climate system. It is primarily driven by human activities such as the burning of fossil fuels and deforestation.

congrats on reading the definition of Global climate change. now let's actually learn it.

5 Must Know Facts For Your Next Test

  1. The primary greenhouse gases contributing to global climate change include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
  2. Increased atmospheric CO2 leads to ocean acidification, which negatively impacts marine life.
  3. Rising global temperatures are causing polar ice caps and glaciers to melt, leading to sea level rise.
  4. Climate change can disrupt ecosystems, leading to shifts in species distribution and increased extinction rates.
  5. Extreme weather events such as hurricanes, droughts, and heatwaves are becoming more frequent and severe due to global climate change.
