Study Notes
Global Atmospheric Changes
- Global atmospheric changes include significant and long-lasting changes in Earth's climate and weather patterns.
- These changes threaten food production, increase sea levels, and create risks of catastrophic flooding.
- Key factors sustaining life include solar energy, biogeochemical cycles, and gravity.
- Human activities, including fossil fuel combustion and deforestation, are major contributors to observed climate changes, especially in the last six decades.
- Natural causes of climate change include volcanic eruptions (releasing ashes, dust, toxic gases) and orbital changes (Earth's orbit variations).
- The carbon dioxide theory proposes that increasing carbon dioxide levels make the atmosphere opaque, trapping outgoing radiation, and raising temperatures.
Weather
- Weather describes atmospheric conditions at a specific time and place.
- Weather patterns change frequently (minutes, hours, days, or even weeks).
- Weather elements include temperature, atmospheric pressure, precipitation, cloudiness, humidity, and wind.
- Examples of weather conditions include sunny, partly sunny, partly cloudy, sun and rain, raining, thunderstorms, snowing, cloudy, windy, rainbow, tornados/hurricanes, and clear.
Climate
- Climate refers to the long-term average of weather conditions in a particular region.
- Climate factors include solar intensity, Earth's distance from the sun, Earth's tilt, distribution of water and landmasses, and atmospheric gas composition.
- Other climate factors include latitude, elevation, distance from the ocean, geographic location, wind, humidity, fog, cloud cover, and lightning (in certain areas).
- Climate patterns can persist for weeks, months, or years.
Global Climate Change
- Human activities are a major cause of global climate change.
- Climate change includes rising temperatures, changes in precipitation patterns, shrinking snow and glaciers, and ongoing human activities.
- Greenhouse gases (water vapor, carbon dioxide, methane, nitrous oxide, ozone, CFCs, and halocarbons) trap heat and warm the Earth's surface.
Greenhouse Effect
- The greenhouse effect is a natural process that warms the Earth's surface.
- Without the greenhouse effect, Earth's average temperature would be significantly colder.
- Human activities, such as burning fossil fuels, agriculture, and land clearing, increase greenhouse gas concentrations, enhancing the greenhouse effect and resulting in global warming.
Health Effects of Climate Change
- Climate change is expected to cause approximately 250,000 additional deaths per year between 2030 and 2050.
- Rising global temperatures will increase heat stress, heatstroke, and cardiovascular and kidney diseases.
- Worsening air pollution negatively affects respiratory health, especially for people with asthma.
- Extreme weather events like storms and flooding can lead to injuries, drinking water contamination, and damages to infrastructure.
Loss of Natural Resources
- Climate change is overwhelming the capacity of ecosystems like forests, barrier beaches, and wetlands to buffer extreme weather events (fires, floods, and storms).
- Rising ocean temperatures impact marine life and reduce food production, harming fishing communities.
Changes in Natural Habitats
- The Arctic is heating at a faster rate than other regions on Earth, causing ice sheets to melt and sea levels to rise.
- Climate change alters growing seasons, intensifies and lengthens allergy seasons, and negatively impacts the habitats and species of different organisms.
Changing Ocean Chemistry
- Earth's oceans absorb fossil fuel emissions; this makes them more acidic.
- More acidic oceans threaten underwater life, particularly organisms with skeletons or shells (oysters, clams, and coral).
- Ocean warming further impacts the range and population of underwater species, contributing to coral bleaching events.
Protocols and Mitigation Strategies
- International protocols, such as the Montreal Protocol and Kyoto Protocol, aim to address global warming and reduce greenhouse gas emissions.
- Mitigation strategies include reducing energy use, increasing energy efficiency, switching to hybrid or electric vehicles, using renewable energy sources, planting trees and managing forests, and managing carbon.
Adaptation Strategies
- Adaptation strategies involve adjusting to the consequences of climate change.
- These strategies include protecting coastal lands from rising sea levels, relocating coastal communities, and adapting to changing agricultural zones.
Ozone Layer Depletion
- The ozone layer protects Earth from harmful ultraviolet (UV) radiation.
- Ozone depletion occurs due to human-released pollutants (CFCs and halons).
- The depletion of the ozone layer causes problems like eye damage and skin cancer.
Ozone Layer Depletion: International Efforts
- The Montreal Protocol (an international commitment) aims to phase out chemicals depleting the ozone layer.
- Volcanic eruptions can temporarily reduce ozone levels.
Conclusion
- Human activities significantly impact Earth's climate.
- Various protocols, mitigation, and adaptation responses are important.
- There is a need for collective action to address climate change.
