That is what BP thinks will happen on the basis of projecting forward what we are doing to date. However, in what they see as a Rapid Transition Scenario, BP still sees around half of our energy needs in 2040 coming from fossil fuels in the form of gas and oil. Here from the BP Energy Outlook, 2019 in a nutshell is the story:
The best wind farms in the world are already competitive with coal, gas and nuclear plants. But over the next five years, continued performance improvements and cost reductions will bring the average onshore wind plant in line with cheap natural gas, even without a price on carbon.
These posts include a brief mention of a number of news items relating to climate change. They don’t preclude treating any of these topics at more length in a separate post.
They can also serve as an open thread so that we can keep each other informed on important climate news.
Beware the collapse of the planet’s lungs
Amazon drought is consistent with what scientific models predict for a warmer globe.
Normally, rainforests function like great carbon sinks, absorbing a large proportion of the CO2 that human activity produces. But in 2005, thanks to deforestation, the Amazon became a net emitter of carbon dioxide. In that year, the rainforest is estimated to have emitted some 5 billion tonnes of CO2, almost as much as the entire output of the United States.
Reefs are the ocean’s canaries and we must hear their call. This call is not just for themselves, for the other great ecosystems of the ocean stand behind reefs like a row of dominoes. If coral reefs fail, the rest will follow in rapid succession, and the Sixth Mass Extinction will be upon us — and will be of our making.
Now at Climate Progresswe are told that the current season looks like the second worst on record. This is how the Australian sea surface temperature has been going;
If ocean temperatures and ocean acidity continue to rise in Australian waters at the same pace as has occurred over the past 100 years, the Great Barrier Reef will be in significant danger by 2050.
