What is Global Warming: Define, Causes, Steps & Effects

Global warming is one symptom of the much larger problem of human-caused climate change Global warming refers only to the Earth’s rising surface temperature, while climate change includes warming and the side effects of warming like melting glaciers, heavier rainstorms, or more frequent. Global warming is also termed as climate change. Global warming is the steady and continuous rise in the level of earth temperature. The main cause of global warming is the human beings careless activities.  Out earth, the surface is becoming hotter day by day just because of some unnoticeable habits of human beings all over the world. Global warming has become the most worrying threat to the earth’s atmosphere as it is reducing the life possibilities on the earth day by day through a continuous and steady declining process. Global warming is the process that causes the earth’s temperature to rise and makes the earth warmer. Human being plays a major role in the earth’ temperature. It is observed in the rise of the earth’s temperature of the climate system and its related effects. Many lines show that the climate system is warming. The further climate changes and impacts will differ from region to region. Forecast effects include increasing global temperatures rising sea levels, changing precipitation and expansion of deserts in the subtropics. Warming is expected to be greater over land than over the oceans and greatest in the Arctic. Other changed include more frequent extreme weather events such as heat waves, droughts, heavy rainfall with floods and heavy snowfall. Effects remarkable to humans include the threat to food security from decreasing crops yields and the neglect of populated areas due to the rising sea levels.

Causes of global warming

The greenhouse is caused by showing that water vapor and other atmospheric gases absorbed Earth’s radiant heat. Water vapor levels, therefore, tend to adjust quickly to the prevailing conditions, such that the energy flows from the Sun and re-radiation from the Earth. Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally, this radiation would escape into space but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That’s what’s known as the greenhouse effect. There are many causes of the global warming which affects human lives and health in many aspects. The main cause of global warming is the human beings careless activities. Ever increasing human population are demanding more resources to live an easy and healthy life such as land to live and crop cultivation, technological growth for comfort and deal with increasing temperature of the atmosphere, etc. Fossil fuels burning for many reasons are highly responsive to increase global warming.

Steps to stop global warming: 

Steps to stop global warming

  1. Regular replace of shining bulbs: Replace regular shining light bulb with compact fluorescent light bulbs. They consume 70 less energy than ordinary bulbs and have a longer lifetime.
  2. Reduce, Reuse, Recycle: Reduce your need to buy new products or useless, resulting in a smaller amount of waste. Even if you need to buy, consider buying eco-friendly products.
  3. Use Less Hot Water: Buy energy saving geysers and dishwasher for your home. Avoid washing clothes in hot water. Just wash them in cold or warm water. Avoid taking frequent showers and use less hot water. It will help in saving energy required to produce that energy.
  4. Turn Off the Lights: If you’re not using a room, there’s no need for the light to be on.

Effects of global warming

Climate change will ultimately impact human lives. Impacts on human lives will depend upon how much change in frequent floods. More frequent heavy rain events will result in more flooding.

  • Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the risk of wildfires in the American West.
  • Rising sea levels will lead to coastal flooding on the Eastern Seaboard, especially in Florida, and in other areas such as the Gulf of Mexico.
  • Forests, farms, and cities will face troublesome new pests, heat waves, heavy downpours, and increased flooding. All those factors will damage or destroy agriculture and fisheries.
  • Disruption of habitats such as coral reefs and Alpine meadows could drive many plant and animal species to extinction.
  • Allergies, asthma, and infectious disease outbreaks will become more common due to increased growth of pollen-producing ragweed, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes.
