It took more than 20 years to broadly accept that mankind is causing global warming with the emission of greenhouse gases. The drastic increase in the emission of CO2 (carbon dioxide) within the last 30 years caused by burning fossil fuels has been identified as the major reason for the change of temperature in the atmosphere. “The main cause of global warming is our treatment of Nature”.

We believe to be able to control Nature instead of trying to arrange ourselves with Nature. This haughtiness is the true main cause of global warming. As a matter of fact, some people still believe that technical solutions alone would be sufficient to fight global warming.

“In our technology and scientific minded world, we seem to have forgotten that mankind is only a relatively minor part of Nature. We ignore being part of a larger whole”.

‘The main questions is that can technology help us to change our climate’ ?

There is no single solution to global warming, which is primarily a problem of too much heat-trapping carbon dioxide (CO2), methane and nitrous oxide in the atmosphere. The technologies and approaches outlined below are all needed to bring down the emissions of these gases by at least 80 percent by mid-century.

1.Boosting energy efficiency 2. Greening transportation 3.Revving up renewables 4. Phasing out fossil fuel electricity 5. Managing forests and agriculture 6. Exploring nuclear  7.Developing and deploying new low-carbon and zero-carbon technologies 8. Ensuring sustainable development. 

As the Climate Hot Map demonstrates, the impacts of a warming world are already being felt by people around the globe. If climate change continues unchecked, these impacts are almost certain to get worse. From sea level rise to heat waves, from extreme weather to disease outbreaks, each unique challenge requires locally-suitable solutions to prepare for and respond to the impacts of global warming. Unfortunately, those who will be hit hardest and first by the impacts of a changing climate are likely to be the poor and vulnerable, especially those in the least developed countries. Developed countries must take a leadership role in providing financial and technical help for adaptation.

To be sure, powerful new market forces are at work: Governments beyond Europe are set to impose limits on greenhouse gases, and companies in a range of sectors are searching hard for ways to curb emissions. But technology deployment always takes time. If inventions turned out not to be scalable in a short enough period of time, then businesses and policy makers could shift resources into alternatives, such as adaptation efforts or strategies for taking greenhouse gases out of the atmosphere. the technology can help us in case of the climate change but it is require a lot of time, which per calculations by scientists we will lose many things from our planet so we must take action beside the technology. and we must remember one more thing “the number one solution to climate change is not a technology at all; it is political will”.

Will it be Zero Emission on 2050?

Many people between 20 and 65 years seem to live for the one and only purpose of earning as much money as possible in order to be able to buy as many things as possible. In this light, it is not surprising that discussions about potential solutions to fight global warming concentrate on technical measures instead of a fundamental change of our attitude to life in general and to Nature in particular.

Although we are guests on Earth, we behave as if no further visitors would arrive after us. It’s like having a wild party where we destroy beds, the kitchen as well as the living room of a hotel without ever thinking about our future staying in the hotel nor about other guests arriving later. Will we understand this hint of Nature to follow the true meaning of life or will we continue to let us manipulate by media and advertisement as sheer and willing consumers in the economic cycle? Will we continue to strive for power, prestige and possessions following the concept “the more the better”? Shall economic growth and an ever increasing personal income continue to be the reason for being here, beyond everything else?

Let’s emphasize it again: Not the others need to change, we must change ourselves. There are no international treaties or additional national laws required to start changing. We can start to change our consciousness immediately. It is really only about our personal behavior - independent of what others do or don’t do. Given the evidence that continued emissions of greenhouse gases will cause increasingly serious climate effects, it is necessary to consider how, and at what level, to constrain emissions.

To achieve these climate targets requires a global reduction in emissions. And in deciding how much reduction is necessary it is important to understand that the temperature increase by 2100 is primarily a function of the total emissions over time, rather than the level of emissions in 2050 alone.

The Committee gave consideration to a range of potential emissions scenarios. These varied according to the period in which it is assumed that global emissions peak; the pace of emissions reduction which follows that; and the ultimate emissions floor. The CCC’s conclusion was that to meet the climate objective, global emissions should peak by 2020 and be halved (or more) by 2050. This means that following the peak, global CO2 emissions will need to fall by a rate of 3-4% a year.

Few tips about emission reduction across the globe .

1.  Travel

Cars are the highest source of greenhouse gases from households and account for 34% of the total emissions. To reduce your greenhouse gas emissions, aim to leave your car at home once a week.

2.  Water Heating

Hot water is the second highest source of greenhouse gases generated by households.

3.  Electronic Appliances

Turn electrical appliances off at the wall.

4.  Heating and Cooling

Don’t over-heat or over-cool your home. A difference of one degree can reduce energy consumption and greenhouse pollution by up to 10%.

5.  Refrigeration

The fridge uses a lot of energy and the older your fridge is, the higher the probability that it will be a big polluter.  Simple actions you can make that will save you up to half a tonne of greenhouse gases.

Why to Act Now

Substantial scientific evidence indicates that an increase in the global average temperature of more than 2°F above where we are today poses severe risks to natural systems and human health. To avoid this level of warming, the U.S. needs to reduce heat-trapping emissions by at least 80 percent below 2000 levels by 2050. Delay in taking such action today will mean facing the need for much steeper cuts later, which will likely be more difficult and costly.
