What is the meaning of global warming?

The phenomenon of constant rise in the average temperature of the Earth is referred to as global warming. When we burn fossil fuels like coal, oil, and gas, for example, greenhouse gases are discharged into the environment. These gases trap heat from the Sun, warming the globe and producing a variety of environmental changes and problems.

 

What is the difference between weather and climate?

Weather and climate are two different yet related concepts. The difference is as follows:

  • The term “weather” refers to the short-term atmospheric conditions in a given location, which are often observed across hours or days. Aspects such as temperature, humidity, precipitation, wind speed, and air pressure are taken into account. Weather patterns can shift quickly and vary from day to day, or even within a single day.
  • Climate, on the other hand, refers to long-term trends and averages of weather conditions recorded over a lengthy period of time, generally decades or centuries. Aspects such as latitude, height, ocean currents, and atmospheric variables all influence climate. Climate gives a more comprehensive picture of the normal weather patterns and trends in a certain location.

 

Causes of Global Warming

Global warming is caused by man made activities as well as natural occurring events.

Man-made causes of global warming are

  • Burning fossil fuels: The combustion of coal, oil, and natural gas for energy production and transportation emits significant amounts of carbon dioxide (CO2), the primary greenhouse gas.
  • Deforestation: Clearing forests for agriculture, urbanisation, and logging reduces the Earth’s capacity to absorb CO2, contributing to higher atmospheric CO2 levels.
  • Industrial processes: Certain industrial activities, such as cement production, chemical manufacturing, and metal smelting, release greenhouse gases like CO2, methane, and nitrous oxide.
  • Agricultural practices: Intensive livestock farming, rice cultivation, and the use of synthetic fertilisers release methane and nitrous oxide, both potent greenhouse gases.
  • Waste management: Improper waste disposal in landfills generates methane as organic waste decomposes, adding to greenhouse gas emissions.

Natural causes of global warming are 

  • Solar radiation: Variations in solar radiation reaching the Earth can influence climate patterns and contribute to changes in global temperatures over long periods.
  • Volcanic activity: Volcanic eruptions release gases, including carbon dioxide and sulphur dioxide, as well as ash and aerosols that can affect the Earth’s climate temporarily.
  • Changes in Ocean Circulation: Natural variations in ocean circulation, such as El Niño and La Niña events, can impact the distribution of heat and influence global climate patterns.
  • Natural greenhouse gas emissions: Natural sources like wetlands, termites, and oceans release methane, a potent greenhouse gas that contributes to global warming.

 

Impacts of Global Warming:

Here are five major effects of global warming:

  • Rising temperatures: Global warming leads to increased average temperatures worldwide. This can result in heatwaves, causing heat-related illnesses and deaths, as well as putting stress on ecosystems, agriculture, and infrastructure.
  • Melting ice and rising sea levels: Global warming causes the melting of glaciers, ice caps, and polar ice sheets. The resulting water contributes to rising sea levels, threatening coastal communities, low-lying islands, flooding and coastal ecosystems.
  • Extreme weather events: Global warming intensifies certain types of extreme weather events. This includes more frequent and severe heat waves, droughts, heavy rainfall, hurricanes, and storms. These events can lead to property damage, infrastructure failure, crop loss, and threats to human lives and well-being.
  • Ecosystem disruptions: Global warming disrupts ecosystems and biodiversity.
    Changes in temperature, precipitation patterns, and other climate factors can impact the distribution and abundance of plant and animal species. This can result in habitat loss, species extinction, and imbalances in ecosystems, affecting overall ecological stability and services.
  • Human health impacts: Global warming poses risks to human health. Heatwaves and extreme temperatures can cause heatstroke, respiratory issues, and cardiovascular problems. Changes in climate patterns can also influence the geographic distribution of diseases, increase the prevalence of certain infectious diseases, malnutrition and related health issues.

 

Solutions to Global Warming:

Addressing global warming requires a comprehensive approach involving various solutions. Here are five main global warming prevention strategies:

  • Transitioning to renewable energy sources like solar and wind power to minimise dependency on fossil fuels and greenhouse gas emissions.
  • Implementing energy-saving techniques in buildings, industry, and transportation to minimise energy usage and carbon impact.
  • Encouraging sustainable land use practices, such as reforestation and sustainable agriculture, to improve carbon sequestration and ecosystem protection.
  • Strengthening international collaboration and agreements to set emission reduction objectives and encourage information exchange and technology transfer.
  • Adopting sustainable waste management practises, such as recycling and trash minimization, to reduce landfill methane emissions.
  • Educating and creating awareness among individuals and communities about the necessity of sustainable living and decreasing personal carbon footprint.
  • Investing in research and development to create cleaner technologies, carbon capture and storage solutions, and climate-resilient infrastructure in order to minimise and adapt to the effects of global warming.

 

Ultimately, global warming presents serious hazards to our world and needs quick action. Transitioning to renewable energy, preserving natural resources, and implementing sustainable practices are critical to mitigating the effects of climate change and ensuring a sustainable future.
