Meanwhile Global Carbon Dioxide Emissions Set New Record
In June of this year, the Mauna Loa Observatory in Hawaii recorded an average concentration of atmospheric carbon dioxide above 410 parts per million (ppm). This was the highest monthly average in recorded history, and in fact according to ice core records it is the highest value in at least 800,000 years.
As of June 29 levels are even higher at 411.95ppm.
The worrisome part is that the trend isn't expected to change anytime soon. Carbon dioxide that is emitted today takes time to accumulate in the atmosphere, and then it remains in the atmosphere for thousands of years.
In any case, there are no signs that what we are emitting is slowing down.
The 2018 BP Statistical Review of World Energy that was released earlier this month showed a new all-time high for global carbon dioxide emissions in 2017, which were 426 million metric tons higher than in 2016. This was 1.6% higher than carbon dioxide emissions in 2016, and was higher than the 10-year average growth rate of 1.3%.
Since the Kyoto Protocol -- the international treaty that commits state parties to reduce greenhouse gas emissions -- went into effect in 2005, global carbon dioxide emissions have increased by 19%.
The countries responsible for the increase in carbon dioxide concentrations have shifted in recent decades. Developed countries are moving away from coal, and toward cleaner natural gas and renewables. Developing countries -- even those that are embracing renewable energy -- emit the most carbon dioxide, and their emissions are growing at the fastest rates in the world.
