Spray chemicals to the atmosphere to prevent sunlight break global temperature increase in the half without any dangerous effects, Harvard scientists have suggested.
Solar geoengineering has long been bloomed as a possible means of tackling global warming, but many are concerned about its potential for unnecessary side effects.
Injecting aerosols in the air can be extraordinarily even aggravating climate problems by interfere with rain in some regions.

But with increasing concern about the devastating impact of climate change, experiments are already in the process to establish how effective such techniques could be.
In a new study, the research team used computer models in an attempt to measure the perfect "dose" geoengineering that would slow down heat without doing anything.
1/8 Davos 2019: David Attenborough gives noticeable notice of the future of civilization as he asks for practical answers & # 39; to tackle climate change
Sir David Attenborough has announced a noticeable warning on climate change to business figures collected in Davos, telling them that "what we do now … will affect the next thousands."
On the eve of this year's World Economic Forum, the renowned naturalist told the audience that business and politics should "go on with the practical solutions" needed to prevent environmental damage.
"As a species we solve specialized problems, but we have not yet applied ourselves to this problem with the focus that it requires.
"We can create a world with clean air and water, unlimited energy, and fish stocks that will sustain us well for the future. But to do that, we need a plan," he said.
The broadcaster made his speech after receiving a Crystal Award, awarded by the forum to "outstanding cultural leaders".

2/8 At least 60% of wild coffee species face devastation caused by climate change and disease
Two decades of research have revealed that 60 per cent of the world's coffee species are facing devastation due to the combined threats of deforestation, disease and climate change.
Arabica wild strain, the largest coffee used on the planet, is among those now recognized at risk, raising concerns about its long-term survival.
These results are causing concern to the millions of farmers around the world that rely on continued coffee continuity for their livelihood.
As the conditions for coffee farming become quicker, scientists will predict that the industry will need to rely on wild species to develop more resilient stresses

3/8 Heating Antarctic waters accelerate the rate where the glacier melts
The Antarctic ice leaflet loses six times each year as it was in the 1980's and the pace accelerates, one of the most comprehensive studies of the effects of climate change on the continent have shown.
More than half an inch has added to global sea levels since 1979, but if the current trends continue, it will be responsible for larger meters in the future, found the study funded by Nasa .
The international effort used aerial, satellite data and climate models dating back to the 1970s across the 18 Antarctic regions to have the most complete picture to date on changing climate effects .
He found that Antarctica between 1979 and 1990 lost an average of 40 gigatonnes (40 billion tonnes) of mass annually.
Between 2009 and 2017 an average of 252 gigatonnes per year lost. This has added 3.6mm per decade to sea levels, or about 14mm since 1979, the study shows

4/8 Greater Manchester to ban fracking, pavement for conflicts with government over controversial industry
Great Manchester is to effectively ban fracking, raising the possibility of a fresh conflict with government over the controversial industry.
Each of the 10 councils in the region is to implement planning policies that create a "assumption" against drill for gas chalele in their areas, the mayor of Manchester Andy Burnham has announced.
The campaigners said that the move was the latest sign that the tide turned against fracking, which has been the subject of a host of legal battles across the country.
Bracking critics say it poses environmental and health risks. The only drilling of the UK operational fraction site, run by Cuadrilla in Lancashire, has been suspended repeatedly due to ground conglomerations.
But ministers are supporting industry that last year unveiled plans to accelerate the development of new drilling sites

5/8 Japan confirms a plan to resume commercial whales in its waters from next year
Japan will restart commercial whales next year for the first time in more than three decades, in movement that has driven strong criticism from campaigners and the international community.
Cabinet secretary secretary, Yoshihide Suga, said that his nation would leave the Whale International Commission (IWC) to resume hunting of marine mammals in Japanese waters.
However, he said that the activity would be limited to the territory of Japan and the 200-mile unique economic zone along its coasts.
This means "scientific" controversial tours to Antarctica where shipping from Japan kills hundreds of whales, as well as activity in the Pacific North West, will stop in 2019

6/8 COP24: Environmental groups criticize an unacceptable climate & misconception agreement which arrived after a great Polish summit
Diplomats from all over the world have agreed a great deal of climate after two weeks of United Nations discussions in Poland.
But climate campaigners warned the agreement – an effective set of rules for how to govern the 2015 climate balance of Paris – agreed between almost 200 countries without ambition or a clear promise of climate action.
Activists welcomed elements of the plan carefully, saying that "important progress" has been made on ensuring that efforts can be measured and compared to tackle climate change by individual countries.
But environmental groups were also extremely critical of the agreement, warning that he did not have ambition and clarity on key issues, including funding for climate projects for developing countries.
The COP24 agreement, which has aimed at providing definitive guidelines for countries on how to report their greenhouse gas emissions and reducing efforts, was confirmed on December 15, after conversations over

8/8 The three largest African elephants casting exposed using DNA from illegal knight shipping
DNA was used from huge hints of an assortment to identify the three largest wildlife trading branches that act at the height of the African elephant hot epidemic.
Ivory tends to be transported around the world from African ports in bulk, and scientists have used genetic evidence collected from intercepted sacks to reveal their origin.
Led by Dr Washington Wasser of the University of Washington, he looked at several of these ships to three chapters operating from Kenya, Uganda and Togo.
The evidence collected by Dr Wasser has already assisted the conviction of Kingpin Mosal Mohamed Ali, and as the team joins dots between shipping, they intend to clean up the cases against more from the richest smokers of the continent

Although the scientists recognize that there is still a lot of uncertainty about this dramatic intervention, it was suggested that this could lead to significant benefits overall.
"The analogy is not perfect but the geoengineering of the sun is like a drug that is treating a high blood pressure," said Dr Peter Irvine, who led the study.
"Overdose would be harmful, but a well-chosen dose could reduce your risks."
Although Dr Irvine has indicated that "better not to have high blood pressure in the first place", once the problem was in hand, he said it was definitely worth considering the options.
Experts have warned, to avoid the worst effects of climate change, greenhouse gas emissions have to halve between now and 2030 – a target that the world is not on track to hit .
Dr Irvine noted his colleagues investigating how effective a limited geoengieering program, as well as emissions cuttings could be effective.

They concluded that using such techniques to halve warming would not only be cool in the planet but also help to cut some of the extreme weather effects associated with it. heated, such as hurricanes increasing in intensity.
In this situation, researchers found that only 0.5 per cent of land would see the effects of a potentially damaging climate if the intervention was.
"Major uncertainty continues, but climate models suggest that geoengineering could enable the benefits of surprise in uniform," said Professor David Keith, who was the study author.
The research was published in the magazine Nature of Climate Change.
Another study that tried to measure the far-reaching effects of solar geoengineering announced last year could be "extremely cheap" if the current aircraft were adapted to discharge the aerospace to the air.
However, other research has warned that such efforts could harm global agriculture, and concentrating on such great solutions is to highlight the serious business of cutting off emissions.
So far, the attempts to test the principles have been moderate. Professor Keith is part of a group that launches a balloon to mimic a large volcanic blast by spraying a 12 mile chalk dust above the Earth in a small-scale test of the feasibility of the technique.
