Study Notes

Learning Outcomes

Understanding the definitions and distinctions between global warming and climate change and their impacts.
Exploration of the origin and progression of global warming.
Discussion on potential negative effects of climate change on humanity.
Strategies and individual actions to combat climate change.

Definitions

Climate Change: Refers to long-term alterations in weather patterns, encompassing average temperature and precipitation.
Global Warming: The ongoing rise in Earth’s average surface temperature due to greenhouse gas emissions.

Greenhouse Effect

Greenhouse gases capture heat and retain it close to the Earth’s surface, leading to a warming effect known as the greenhouse effect.

Global Temperature Trends

Average surface temperature has increased by approximately 1.78°F (0.99°C) since the late 19th century.
As of May 2022, global atmospheric CO2 concentration reached 421 ppm.

Causes of Climate Change

Natural Causes: Influences that alter the climate naturally.
Human Causes: Increasingly responsible for climate change, primarily through emissions from industrial activities.

Differences Between Climate Change and Global Warming

Global warming focuses specifically on the rise in temperature, while climate change encompasses broader climatic shifts, including temperature and precipitation changes.

Effects of Global Warming

Lengthening and intensification of summer seasons.
Shorter and milder winters.
Increased intensity and frequency of tropical storms.
Rise in sea levels due to melting ice and thermal expansion.
Significant impacts on habitats and biodiversity.

Notable Global Climate Facts

The 1990s marked the warmest decade of the last millennium.
Snow cover decreased by 10% over the last 40 years.
Arctic summer sea ice faces disappearance in the latter half of the century.
Global atmospheric CO2 levels grew by 30% in the past 200 years.

Anticipated Climate Change Consequences

Over one billion people in Asia projected to face water shortages by 2050.
Shifts in monsoon patterns could lead to severe droughts and flooding.
Dependency on rain-fed agriculture increases food supply vulnerability due to climate variability.
Higher incidence of waterborne diseases and respiratory disorders as a result of climate change.

Strategies to Combat Climate Change

Reduce, Reuse, Recycle: Essential principles for minimizing waste and conserving resources.
Emphasis on renewable energy sources such as wind and solar power.
Engagement in electric vehicle adoption to reduce pollution and reliance on fossil fuels.

Practical Individual Actions

Power off electronic devices when not in use to save energy.
Limit showering time to conserve heating energy.
Ensure air conditioning and furnace filters are clean for efficient operation.
Adjust clothing according to temperature to minimize heating and cooling energy use.
