[But] the root causes of these symptoms remain societal and personal choices that lead the average American to burn more than twice as much fossil fuel as the global average. As California Gov. Jerry Brown and others have demonstrated, the West also could lead the way in addressing these root causes. See the website for the We Are Still In coalition.
The complexity of climate change means it’s hard to trace simple lines from cause to effect in daily life, much less plan for the future. That’s one reason the federal government updates its National Climate Assessment every four years — to provide lawmakers, policymakers and citizens with the information they need to plan everything from urban infrastructure, to insurance programs, to disaster readiness. After the third NCA came out in 2014, the world experienced three of the warmest years on record. In the same time the United States, along with 167 other signatories, agreed to reduce greenhouse gas emissions in order to keep global temperatures below a dangerous tipping point.
But after last December’s presidential election, the odds of the U.S. willingly contributing to international climate change solutions dwindled. At this year’s United Nations climate conference, the Trump administration — which previously announced plans to withdraw from the international climate agreement — says it will promote fossil fuels and nuclear energy.
All of which makes the fourth NCA seem even more urgent. After all, the U.S. emits more greenhouse gases per person each year than almost every other country in the world. Last week, the government released the first part of its 2018 assessment. Focusing on the science of climate change, the report describes how greenhouse gas emissions are affecting the U.S. already and will continue to do so in future if we continue on the current trajectory.
Here are the takeaways for the West:
