YaGoBin : Google And Nasa VS Gas Emissions
How to monitor our gas emissions? The answer comes from space.
The NASA and Google aim to provide some new tools for measuring levels of CO2 and deforestation based on satellite technology.
NASA already had a scientific satellite , called the Orbital Carbon Observatory (OCO), which could be capable of detecting emissions of CO2. But its launch turned into a disaster,the satellite ended its race in the icy waters of Antarctica.
If it gathers the necessary funding, NASA could build a similar satellite at a cost of 330 million dollars and make it in orbit for three years. The commissioning of the satellite would “maybe” lead countries to act differently.
For its part, Google has announced that the forest countries will have a free access to its “Earth Engine”, a new software storing satellite data
Deforestation is considered a the first cause of climate change. While industrialized countries are going to pay billions of dollars to developing countries to stop the destruction of tropical forests, the Google system would allow anyone to check the condition in which they are.
But technology alone can not solve the problem. Cooperation between countries like the United States and China, the two biggest polluters, is needed to verify the reduction of emissions.
China is building so many coal plants that it is difficult for experts to have a precise knowledge of their production of carbon dioxide. The launch of a new NASA satellite that can detect emissions of CO2 could be very useful in this case.
As long as such a satellite is not in use, the assessment of carbon emissions will involve many uncertainties, in calculus , appliances and a good dose of confidence between different actors.
The ability to estimate emissions from each power plant is also crucial for the establishment of a system of emissions trading, as envisaged in the United States, which would allow companies to buy “pollution rights” to others that have reduced their emissions.
