The solutions Climate change is caused by human activities. When we burn fossil fuels, we release carbon pollution into the air. Forests help to absorb this carbon dioxide, so deforestation also contributes to the planet's warming. However, carbon dioxide isn't the only greenhouse gas.
Share via Email Humanity could not exist without it - yet in an extraordinary plan that underlines the catastrophic implications of climate change, scientists now want to curb the Sun's life-giving influence to save mankind from its biggest threat: Key talks involving the Government's most senior climate experts have produced proposals to site a massive shield on the edge of space that would deflect the Sun's rays and stabilise the climate.
Hundreds of thousands of tonnes of metallic 'scatterers' would be ejected into the upper atmosphere under the plans. In addition, billions of tiny barrage balloons could serve as a secondary barrier to block rays from the Earth's nearest star.
On land, giant reservoirs holding saline water could be built to offset the rise in sea levels caused by the melting of the polar ice-caps.
The oceans, too, would be modified to cope with the planet's increasingly warmer weather. Massive floating cloud-making machines would be dotted across their surface while, below, large plantations of algae would be grown to absorb greenhouse gases from the atmosphere.
The theories were discussed by Britain's most eminent climatologists at a meeting in Cambridge last week to analyse the latest theories to tackle the problem of the planet heating up.
They included the Government's chief scientist, Sir David King, who warned last week that climate change was the most severe problem facing civilisation. Professor John Schellnhuber, former chief environmental adviser to the German government and head of the UK's leading group of climate scientists at the Tyndall Centre, said: But the problem has not gone away, so we think this analysis is just in time.
We are not saying we have the magic bullet, but this is a desperate situation and people should start thinking about the unconventional. Preventative plans on a larger scale are needed. Last week researchers predicted that a quarter of land animals and plants will die out because of global warming over the next 50 years.
Scientists, however, argue that until the United States and Russia ratify international agreements to limit the emission of greenhouse gases they will have little choice but to explore new methods to save the planet.
Extreme technological fixes include deploying tens of billions of wafer-thin metal plates less than a centimetre wide into the Earth's low orbit via space rockets.
These would be specially built to allow space-bound rays to pass while at the same time absorbing a significant amount of solar energy before bouncing it back into space. They would be designed to stay in place for a century.
Similar solutions include the release of massive nets of ultra-fine metal mesh into the upper atmosphere by aircraft to prevent the Sun's rays from reaching Earth. Alternatively, millions of metallic-coated super-pressure balloons - similar in design to a children's party version, although a fraction of the size - would be filled with helium and released until they reach the stratosphere 35,ft above the Earth.
Trapped in parcels of air, they would stay up for about five years before falling to earth and being replaced. All the methods are designed to block about 1 per cent of the Sun's rays, enough to protect at least one million square kilometres of the Earth and significantly cool the planet.
Inspiration came from studying the effects of volcanic eruptions in Indonesia in During these explosions, enough material was spewed into the upper atmosphere to cause temperatures to fall by up to 30 per cent for almost three years, roughly the amount some predict that they will rise to by the end of this century.President Trump has claimed that scientists stopped referring to global warming and started calling it climate change because “the weather has been so cold” in winter.
Climate change and wildfires – how do we know if there is a link? What climate change is happening to other planets in the solar system.
Volcanoes can have both a cooling and warming effect on the planet's climate • See all questions and answers • Read about the project. Vital Signs of the Planet: Global Climate Change and Global Warming. on the scale of the human lifespan. Today, we know that our climate is changing at an unprecedented rate and that humans are a key part of that change. El Chichon) that throws out a tremendous amount of particles and other gases. These will effectively shield us enough. But could a giant space umbrella help cool down our planet? Zaria Gorvett investigates. the Intergovernmental Panel on Climate Change but how we’d do it sounds more far-fetched. To.
I would also like to see some scientific reference explaining why it is reasonable to assume that we can detect a climate change on a planet whose climate is barely hypothesized.
I would also like to.
Keeping our planet clean and healthy is important, and we do need to make sure that we work to improve and not destroy Mother Earth.
But climate change is not the single greatest threat facing our planet. FAQ: Climate Change. the planet would not be warm enough to support life as we know it. in an era of generally stable climate.
We just do not know how well we will cope with a radical. Apocalyptic thinking about climate change and human technological development is Manichean and unwarranted.
