Study Notes

Global Warming Overview

  • Global warming is the gradual increase in Earth's average surface temperature.
  • The 2023 was the hottest year on record.
  • 20% of emissions are contributing to the current trend.
  • 3.6 billion people are affected.
  • Global warming and climate change are different but related concepts.

Causes of Global Warming

  • Burning fossil fuels (coal, oil, and natural gas) releases significant carbon dioxide (CO2) into the atmosphere.
  • Deforestation removes trees that absorb CO2, releasing stored CO2 into the atmosphere.
  • Industrial processes (like cement production), agriculture (livestock methane, fertilizer nitrous oxide), and waste management (landfills methane) also contribute.
  • Increased concentrations of greenhouse gases (carbon dioxide, methane, nitrous oxide, and fluorinated gases) trap heat in the atmosphere.

Environmental Impacts

  • Natural disasters like floods, droughts, and storms are increasing in frequency and intensity.
  • Extreme climate changes, such as heatwaves and rising sea levels, are occurring.
  • Changes in rainfall patterns affect crop production and food security.
  • Reduced water supplies due to droughts and glacial melt impact water scarcity.

Economic Impacts

  • Global warming affects agriculture, tourism, and multiple other sectors.
  • Economic losses are associated with impacts.

Social Impacts

  • Global warming increases risks associated with heatstroke, dehydration, and respiratory problems.
  • The health of people are affected by air pollution and smog

Solutions and Actions

  • International agreements like the Paris Agreement aim to reduce emissions.
  • Government and private initiatives play a role in transitioning to renewable resources.
  • Lifestyle changes, such as promoting energy efficiency and driving less, can help mitigate the issue.
  • Increased awareness and spreading information about the effects of global warming can aid in tackling the problem.
