The #NationalClimateAssessment, cynically released by Trump Admin on Black Friday, shows Americans are becoming aware of climate change and starting to tackle it — but too slowly to protect humanity from unimaginable dangers.

Key takeaways threaded here.
Three hints for journalists covering #NCA4:
1. Impacts are felt locally. Look at chapters 18 through 27 for main regional impacts.
2. Don’t let Trump rush you with a Black Friday release. Climate stories need to be told properly.
3. Science deniers are liars. Don’t publish lies.
"Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. The impacts of global climate change are already being felt in the United States and are projected to intensify."
Climate change is a threat we brought on ourselves and are making worse through inaction.

#NCA4 notes impacts are already being felt in communities across the U.S., threatening “human health and safety, quality of life, and the rate of economic growth.”
Warming is making us sicker by reducing air quality, aiding disease transmission, fueling disasters and in other ways, #NCA4 notes.

“Older adults, children, low-income communities, and some communities of color are often disproportionately affected.”
Climate change is an unholy injustice. The new National Climate Assessment says its impacts will “increasingly disrupt Indigenous peoples’ livelihoods and economies, including agriculture and agroforestry, fishing, recreation, and tourism.”
It’s about money as well as wellbeing.

Without “substantial and sustained” work to slow pollution and adapt to changes underway, #NCA4 says warming will “cause growing losses to American infrastructure and property and impede the rate of economic growth.”
Climate change hurts life’s capacity to sustain itself. New federal report warns of “transformative impacts on some ecosystems” unless serious efforts are made to slow warming. It notes some coral reef and sea ice ecosystems are already being devastated.
We have to overhaul America’s aging and deteriorating infrastructure. #NCA4 warns of strains from climate change, with “potential for cascading impacts that threaten our economy, national security, essential services, and health and well-being.” — #NCA4
Even as we have to get better at coping with floods, we have to learn to use less water.

Warming puts more pressure on overburdened water systems, “increasing risks and costs to agriculture, energy production, industry, recreation, and the environment.”
Climate change is truly horrible for farmers.

The National Climate Assessment warns livestock health problems, declines in yields and extreme weather changes here and abroad “threaten rural livelihoods, sustainable food security, and price stability.”
Warming damages coastal cities, tourism and businesses. “Even in a future with lower greenhouse gas emissions, many communities are expected to suffer financial impacts as chronic high-tide flooding leads to higher costs and lower property values.” — #NCA4
What can we do?

More, more, more.

Americans, governments and businesses are tackling climate change by reducing pollution and adapting to changes, but #NCA4 says the work doesn't “yet approach the scale considered necessary to avoid substantial damages.”
The National Climate Assessment contains an exhaustive chapter explaining how to adapt to climate change, providing real-world examples and noting that "adaptation actions in the United States have increased" — but that much more work is needed.
If it wasn't already obvious why Trump admin dropped huge climate report on Black Friday, read Ch. 29. It explains how to ease the crisis by "replacing conventional, CO2-emitting fossil fuel energy technologies or systems with low- or zero-emissions ones."
Two days before his government released a legally mandated review of climate change's growing impacts on Americans and the dire threats it poses to their communities, health and economy, the president was serving up this rote nonsense.
The Trump admin's attempt to bury news of somber climate findings on Black Friday backfired. The news is everywhere.

After details of the plan leaked, the government confirmed the release in advance, giving outlets time to prepare. And yesterday was a slow news day.
