4 Effective solution to reduce global warming

We have seen what Global Warming is and its effects of global warming in earlier posts. Here we shall look into some of the effective solutions & measures for global warming.

Global warming is a phenomenon that is inevitable. Atmospheric temperature has been on the rise. For every 2 Fahrenheit increase, many changes of variable nature occur in the weather, earth’s surfaces and to the diverse ecosystems which cannot be repaired.

Though the greenhouse effect is a natural process that enables the earth to maintain its atmospheric temperature and regulate climate, global warming is man- induced. The emission of greenhouse gases (GHGs) from energy sources, agriculture, motor vehicle emissions and industries are the main causes for this.

As per scientific studies, if the GHGs concentration increases uninterrupted, there can be an increase of up to 10 Fahrenheit. According to the Intergovernmental Panel for Climate Change the global GHGs emissions must be brought down 50-80% to stabilize its concentrations.

A combination of strategies is needed to cut the GHGs emissions. Many of them are in place now but have to scaled up to reduce emission levels

Solution 1: Energy efficiency

Energy production and consumption is major contributor to GHGs emissions. Hence better practice management of its production and its by products will reduce the GHGs levels.

Europe has been historically responsible for the advent of global warming due to heavy industrialization. But since the end of the last century it has begun actively participating in the reducing its carbon emission in various ways. Switching to cleaner renewable fuel for their energy needs has brought down emissions by 7 per cent. Some European countries have also made financial commitments with developing countries to help them with low energy carbon sources, reduce deforestation etc.

Solution 2: Natural sinks

These are the forests and agricultural lands that work to remove carbon dioxide and other GHGs from the atmosphere. The natural carbon and nitrogen cycles take place in green plants.

A very important natural sink in South America was the lush Amazon jungles which are now in a pitiable state. Reduction of deforestation by Brazil over the last five years has made an impact on reducing carbon emissions.

Solution 3: Green Transportation

Another major contributor to global warming is emissions from burning of transport fuels like petroleum and diesel.

An interesting study was done in the US recently to study the services of ride hailing companies like Uber and Lyft. The claim was that they would ease the congestion on the roads by encouraging people to use ride sharing vehicles. But the study suggested that such companies were pulling riders off public transport or their own feet and putting them in cars instead. Many riders were not using ride sharing cars to connect to a subway or bus line, but as a separate mode of transport instead. Thus it increases the congestion.

Solution 4: Princeton’s Stabilization wedges

Scientists Stephen Pacala and Robert H Socolow at the Princeton University have come up with an approach to tackle the stabilization of CO2 emissions using commercially available technology today.  This can be approached as a series of wedges which are the strategies enumerated above. Today there are about 12-14 wedges. The scientists concluded that if the above measures (individual wedges) are implemented in an aggressive mode as early as possible, it can control CO2 emissions to 1 billion tons each year.

As a result, by 2050 we should be able to bring CO2 levels to an average of 450 to 500 ppm globally. The key factor is to start implementing the changes immediately. Even a year delay will increase the financial cost and GHGs levels exponentially.

Conclusion

Economically and technologically we are ready to handle the global warming. But the question is are we politically ready. It is the developed countries such as the US and European countries that are leading in CO2 emissions, with developing countries like India and China following very closely. Each of these should take their responsibility seriously and have working policies and active regulations in place to reduce their contribution to climate changes, as well as help the poorer nations who are actually suffering the consequences, to adopt solutions to combat global warming.
