The safety board says its ongoing investigation is focusing on several key areas, including metallurgical examination of the wing structure, landing techniques, pilot training and the passenger evacuation process.

Jeff Masters, a meteorologist for Yale Climate Connections, pointed to substitutes from insurance brokers and the international disaster database as alternative sources of information.Still, “The NOAA database is the gold standard we use to evaluate the costs of extreme weather,” Masters said, “and it’s a major loss, since it comes at a time when we need to better understand how much climate change is increasing disaster losses.”

These moves also don’t “change the fact that these disasters are escalating year over year,” Kristina Dahl, vice president of science at nonprofit climate organization Climate Central. “Extreme weather events that cause a lot of damage are one of the primary ways that the public sees that climate change is happening and is affecting people.”“It’s critical that we highlight those events when they’re happening,” she added. “All of these changes will make Americans less safe in the face of climate change.”The move, reported Thursday by CNN, is yet another of President Donald Trump’s efforts to remove references to climate change and the impact of greenhouse gas emissions on the weather from the federal government’s lexicon and documents.

Trump has instead prioritized allies in theThe change also marks the administration’s latest hit overall to the weather, ocean and fisheries agency.

The hooked claws are a crucial identification clue, said study co-author and paleontologist Per Ahlberg at Uppsala University in Sweden.“It’s a walking animal,” he said.

Only animals that evolved to live solely on land ever developed claws. The earliest vertebrates -- fish and amphibians – never developed hard nails and remained dependent on watery environments to lay eggs and reproduce.But the branch of the evolutionary tree that led to modern reptiles, birds and mammals – known as amniotes -- developed feet with nails or claws fit for walking on hard ground.
