Scientists have proposed radical measures to combat global warming

Scientists from Cambridge University are going to create a new research center that will study issues and development of technologies that “fix” the Earth’s climate. The researchers intend to consider including a very radical geoengineering approaches to addressing catastrophic nature of climate change, for example, using secondary freezing of the poles of our planet and remove CO2 from its atmosphere.

According to the news Agency BBC, the incentive to create such a research center was the concern of scientists about the fact that currently used approaches for the conservation of the environment will not be able to stop dangerous and irreversible damage exerted on the planet by human activity. The authors of the project believe that their initiative – the first of its kind in the long term can actually lead to significant reductions in emissions and concentrations of carbon in the atmosphere.

The project is coordinated by the former scientific adviser to the British government, Professor sir David king.

“Over the next 10 years we will determine the future of mankind for the next 10,000 years. In the world scientific center, dealing with such issues,” said the king, in conversation with the BBC.

Some examples of the ideas described by king and perspective can help us to solve the problem under discussion, more associated with the so-called geo-engineering. To control Center the restoration of a climate of the Earth will be Dr. Emily Shuckburgh that describes the main task as “solving the climate problem.”

“We have to do it. And we have no right for mistake” — says the scientist.

It is noted that the center will work not only climate scientists, but also engineers and sociologists.

“We are facing one of the most difficult and important tasks in our history, and we should approach its decision with full responsibility and diligence,” says Samburg.

A secondary freezing of the poles


One of the most promising ideas related to the freezing of the poles is in the “bleaching” of the clouds above them, to enhance their reflectivity. For this purpose it is proposed to pump seawater high hydrants installed on an unmanned marine vessels, and spraying her. So, microscopic particles of salt water will create clouds that reflect the light, thus cooling the water and the air beneath them.

Scheme for recycling CO2 into fuel

Another approach is a variation of the scheme, which is called “capture and storage of carbon dioxide” (CCS). This assumes the intake of carbon dioxide emissions from coal or gas-fired power plants or metallurgical plants and burying them underground.

Now Professor Peter Styring the University of Sheffield is developing a pilot scheme for the capture and disposal of carbon dioxide (CCU) in collaboration with Tata Steel in Port Talbot in South Wales. As indicated by Steering, the scheme provides for the creation of an installation that converts carbon dioxide into synthetic fuel using the thermal energy, and operates directly on the spot.

“We have sources of hydrogen, carbon dioxide and heat as well as renewable energy sources on the planet. We are going to combine and start the production of synthetic fuels”, — he shared with the BBC.

The greening of the ocean

Another idea, which is included in the scope of the research the new center is the greening of the oceans algae, so they can absorb more carbon dioxide. Such schemes involve spraying over the ocean waters iron salts that will promote the growth of plankton. However, there is one “but”: the previous studies and experiments have shown that the algae is not able to absorb the carbon dioxide in the right amounts, and such actions can disturb the ecosystem. However, there are those who believe that this risk is justified. According to Professor Callum Roberts of York University, the approaches that are currently considered beyond the scope possible, should be considered and if possible implemented. And all because theis devastating and potentially irreversible climate change in any case not better.

“At the beginning of my scientific career and the terrified people reacted to more interventionist approaches to coral reef conservation. Now those same people are in despair look at the current state of the ecosystem, which will disappear by the end of this century, and now agree to any options, if only to protect nature,” says Roberts.

Examples of these options is the elimination of genetically modified corals with high resistance to elevated temperatures, as well as spraying chemicals in the oceans, to make it less acidic.

“At the moment I think that the use of nature to mitigate the consequences of climate change is the best option. At the same time, I see the possibility of considering even more radical measures, like tools that will provide us the opportunity for a more comfortable future,” adds Robert.

To think of the unthinkable

All of these approaches can result in many dangerous consequences for the planet, but scientists believe that they still need to be addressed, to evaluate the possible negative outcome, and to consider how to implement them with minimal damage. At the same time, some scientists believe that emissions of carbon dioxide in the atmosphere does not correct the situation on the planet.

“If we limit ourselves to reducing CO2 emissions into the atmosphere, only slow down global warming. Sense of this, since the average global temperature is already quite high due to excessively large emissions of carbon dioxide,” says Peter Wadhams, Professor of ocean physics at Cambridge University.

“A more comprehensive approach and the restoration of the climate will bring carbon dioxide from the atmosphere. Reducing its level, we do cool the climate and return it to the values to global warming,” adds the scientist.
