Yet another important warning sign that civilization needs to convert to clean, renewable energy sources, such as those from solar and wind. Pollution is also a leading cause of death anyway, much of it from fossil fuels. And a lot more people should actively understand that what’s profitable to the fossil fuel industry is harmful to the world’s general human populations.
The burning of fossil fuels around the world is set to hit a record high in 2017, climate scientists have warned, following three years of flat growth that raised hopes that a peak in global emissions had been reached.
The expected jump in the carbon emissions that drive global warming is a “giant leap backwards for humankind”, according to some scientists. However, other experts said they were not alarmed, saying fluctuations in emissions are to be expected and that big polluters such as China are acting to cut emissions.
Global emissions need to reach their peak by 2020 and then start falling quickly in order to have a realistic chance of keeping global warming below the 2C danger limit, according to leading scientists. Whether the anticipated increase in CO2 emissions in 2017 is just a blip that is followed by a falling trend, or is the start of a worrying upward trend, remains to be seen.
The new analysis is based on the available energy use data for 2017 and projections for the latter part of the year. It estimates that 37bn tonnes of CO2 will be emitted from burning fossil fuels, the highest total ever.
The main reason for the rise is an expected 3.5% increase in emissions in China, the world’s biggest polluter, where low rains have reduced low-carbon hydroelectric output and industrial activity has increased. India’s rise in emissions was modest compared to previous years at 2%, while the US and EU are both on track for small falls.
2017 is likely to be the hottest year ever recorded in which there was no El Niño event, a natural global cycle that temporarily nudges up global temperature. The concentration of CO2 in the atmosphere also saw a record jump in 2016, and other greenhouse gases such as methane and nitrous oxide from agriculture and industry are also rising.
