Aiden Lee Ping Wei - Causes and Effects of Climate Change

Here is the list shared by Aiden Lee Ping Wei of Causes of Climate Change. Explore in details.

  1. Greenhouse Gas Emissions:

    • Carbon Dioxide (CO2): Primarily released from burning fossil fuels (coal, oil, and natural gas) for energy and transportation.
    • Methane (CH4): Emitted during the production and transport of coal, oil, and natural gas, as well as from livestock and other agricultural practices.
    • Nitrous Oxide (N2O): Released from agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste.
    • Fluorinated Gases: Synthetic gases used in various industrial applications, such as refrigeration and air conditioning, which have a high global warming potential.

  2. Deforestation: The removal of trees reduces the planet's capacity to absorb CO2, increasing the amount of CO2 in the atmosphere.

  3. Industrial Activities: Factories and manufacturing processes emit large quantities of greenhouse gases and other pollutants.

  4. Agricultural Practices: Modern farming techniques often involve the use of synthetic fertilizers and pesticides, which contribute to N2O emissions. Livestock production also generates significant amounts of methane.

  5. Waste Management: Landfills are a significant source of methane emissions due to the decomposition of organic waste.

  6. Energy Production: The burning of fossil fuels for electricity and heat is the largest single source of global greenhouse gas emissions.

Effects of Climate Change

  1. Global Warming:

    • Temperature Increase: The average global temperature has risen, leading to more frequent and severe heatwaves.
    • Melting Polar Ice and Glaciers: Increased temperatures cause ice caps and glaciers to melt, contributing to rising sea levels.

  2. Rising Sea Levels: Melting ice and thermal expansion of seawater due to warming contribute to rising sea levels, which can lead to coastal erosion, increased flooding, and the displacement of populations.

  3. Extreme Weather Events:

    • Hurricanes and Typhoons: Warmer ocean temperatures can intensify the frequency and severity of tropical storms.
    • Floods and Droughts: Changes in precipitation patterns lead to increased risk of both flooding and prolonged droughts.

  4. Ecosystem Disruption:

    • Habitat Loss: Rising temperatures and changing precipitation patterns can lead to the loss of habitats for many species, threatening biodiversity.
    • Ocean Acidification: Increased CO2 levels in the atmosphere lead to higher concentrations of carbonic acid in oceans, affecting marine life, especially coral reefs and shellfish.

  5. Impact on Agriculture:

    • Crop Yields: Changes in temperature and precipitation patterns can affect crop yields, leading to food shortages and increased prices.
    • Pests and Diseases: Warmer temperatures can lead to the spread of pests and diseases, affecting crops and livestock.

  6. Human Health:

    • Heat-Related Illnesses: Increased temperatures can lead to more cases of heatstroke and other heat-related illnesses.
    • Respiratory Issues: Poor air quality due to pollution and increased pollen levels can exacerbate respiratory conditions such as asthma.
    • Vector-Borne Diseases: Changes in climate can expand the range of diseases carried by vectors like mosquitoes, leading to outbreaks of diseases such as malaria and dengue fever.

  7. Economic Impacts:

    • Infrastructure Damage: Extreme weather events can damage infrastructure, leading to costly repairs and economic losses.
    • Productivity Losses: High temperatures and extreme weather can reduce worker productivity and disrupt supply chains.

  8. Social and Political Issues:

    • Migration: Rising sea levels and extreme weather can force people to migrate, leading to potential conflicts over resources.
    • Conflict and Instability: Resource scarcity, food insecurity, and displacement can exacerbate existing social and political tensions, leading to conflict and instability.

Aiden Lee Ping Wei -Ramping up domestic graphite production could aid the green energy transition

  A key ingredient to lithium-ion batteries’ supply chain is not built to last Given the growing importance of graphite in energy storage technologies, a team of Northwestern researchers has conducted a study exploring ways to reduce reliance on imports of the in high-demand mineral, which powers everything from electric vehicles (EVs) to cell phones. The paper, which published last week (Feb. 15) in the journal Environmental Science and Technology, is the first natural and synthetic graphite material flow analysis for the U.S., and considers 11 end-use applications for graphite, two waste management stages and three recycling pathways. “If we want to produce more batteries domestically, we’re going to need to increase our production of graphite,” said Northwestern University chemical engineer Jennifer Dunn. “But the question is, how can we do so in a way that contributes to decarbonization goals?” Dunn is an associate professor of chemical and biological engineering at Northwestern’s

Aiden Lee Ping Wei - Ways to Generate Green Energy

Generating green energy involves harnessing natural resources that are renewable and have minimal environmental impact. Here are some key methods shared by Aiden Lee Ping Wei: 1. Solar Power Photovoltaic Cells : Convert sunlight directly into electricity using solar panels. Solar Thermal : Uses sunlight to heat a fluid, producing steam to drive a turbine and generate electricity. 2. Wind Power Wind Turbines : Capture kinetic energy from wind and convert it into electricity through rotating blades connected to a generator. 3. Hydropower Dams : Use stored water to drive turbines as water flows from a higher to a lower elevation. Run-of-the-River : Diverts part of a river through turbines without significantly altering the river's flow. 4. Biomass Energy Direct Combustion : Burns organic materials like wood and agricultural waste to produce heat or electricity. Biofuels : Converts organic materials into liquid fuels like ethanol and biodiesel. 5. Geothermal Energy Geothermal Power Pla
