What steps need to taken to Prevent the Global Warming

Before going into the steps to prevent global warming, it will be relevant to know what it is all about and the reasons for worldwide concerns about it.

The earth has a natural greenhouse cover that maintains temperatures at a level that fosters plant life and makes it possible for humans and other forms of life to live comfortably. However, since the Industrial Revolution, human activities have affected this fabric that protects the globe, raising average temperatures by almost a degree centigrade. This is what is called global warming and its severity and negative impact can be understood when research shows that the last massive changes in temperatures occurred during the Ice Age. Since then until recently, the average temperature of the earth has been static around 5 degrees Centigrade.

Over the last 100 years or so, the temperature of the earth’s surface has risen by 0.75°C (1.4°F). Of this change, two-thirds has been after 1975, once again showing how vulnerable the earth is today to global warming. Scientists have found that the primary cause of this is accumulation of greenhouse gasses in the atmosphere due to human action. This warming of the earth is raising sea levels and melting polar caps and glaciers resulting in unseasonal rains and floods forcing people to change cropping patterns and way of life.

What then are the steps that you can take to prevent global warming?

Avoiding harmful carbon emissions

Use your car only if you have to. Or better still buy a hybrid car or an electric one. Emission from burning of fossil fuel is considered to be the single largest cause of global warming. Why don’t you ride a bicycle to work, regardless of whether you are a CEO of a multinational or a technician in a company creating strategies based on Blockchain in Melbourne or wherever you may be located? Not only will you be healthier and fitter, you will also be contributing your mite for the preservation of the environment. You can even opt for a car pool membership or take the local public transport to work.

Eat local and fresh foods

Strange as it may sound, this has a definite bearing on global warming. Today, you can have any food you desire regardless of whether it is in season or not. You will find peaches or apples or oranges round the year on supermarket shelves with cartons marked “Made in Mexico” or “Made in Chile” half way around the globe. The point is that transportation of these foods to your country is exponentially contributing to emission of gas from burning of fossil fuel. Buy local foods that are in season. It will not only help the farmers in your country but will also make for a healthy diet.

Reduce water usage

Controlling your water usage to the required minimum can reduce carbon pollution too. This is because a lot of energy is used to treat the water and pump it to your home. After that you will be heating the water which further aggravates the problem. Some statistics are truly mindboggling. Even if one out of every home in the USA is fitted with water efficient fixtures, there will b e a saving of 100 million kilowatt hours of electricity. That translates into 80,000 tons of gasses directly linked to global warming.

By being aware and conscious of the harmful effects of global warming and taking preventive measures to mitigate this problem, you will be paving the way for a better world for generations to come.

Catastrophic Effects of Global Warming and Climate Change

Global warming is the rise in average temperature of the world resulting from rampant de-forestation and loss of green cover, rising pollution levels and emission of harmful greenhouse gasses. The slow but perceptible rise in temperatures has already begun to impact the world in catastrophic ways.

Here are a few effects of global warming and climate change on the Earth.

  • Rising sea levels – Climate change has a direct impact on raising sea levels and this can prove disastrous for many cities. In the last 100 years, average sea levels have risen by about 20 cm and this is expected to be more in the next 100 years. Cities like New York are already going through periodical flooding and by 2050 many others might require sea walls to survive. If the Antarctic and Greenland ice shelves melt and collapse, seas might rise by more than 20 ft, fully inundating large cities around the world.
  • Torrential rainfall and thunder storms – Conditions that produce rainfall might remain static but because of climate change there will be large quantities of water and moisture in the atmosphere. Hence steady rainfall will be a thing of the past and heavy torrential rainfall will be the order of the day. With hurricanes and powerful typhoons becoming more common and frequent, the world will see an increase in flooding, rising sea levels and melting ice caps. Over the last few years there has been a marked increase in premium for those wanting storm and flood insurance in the USA.
  • Droughts and heatwaves – While global warming leads to rising sea levels with disastrous consequences, a similar effect will be felt on land too with rising temperatures resulting in prolonged heatwaves and droughts. Over a period of time places on earth that are hot and dry will get hotter and drier and places with temperate weather with regular rainfall will get much hotter and drier. The record high temperatures being witnessed today around the globe and the occasional droughts and heatwaves will become more of a norm than exception.
  • Changing agriculture patterns – Global agricultural will be strikingly impacted by global warming. For example some crops grow best in specific temperatures. When weather changes their output too will change. Rice which is the staple food of over a third of the world’s population will have a decrease of 10% for every 1 degree Centigrade rise in global temperatures. This can significantly upset the food chain and security. Till recent times this decrease has been partly offset by increased production due to major advances in rice technology but that too is now at the breakeven point.

These are some of the catastrophic effects of global warming which is already visible though partly at present around the world.
