Seattle’s ‘amazing transition’ from wet to dry probably just a coincidence, scientists say
Global warming can’t be blamed for 2017’s wild swings in rainfall, but scientists say slightly wetter winters and drier summers might be more common in the future.
NOAA on Ocean Sounds
NOAA scientists record sound in the deepest part of the world’s ocean and discover a cacophony of sounds both natural and human generated. For three weeks, a titanium-encased hydrophone recorded ambient noise from the ocean floor at a depth of more than 36,000 feet, or 7 miles, in the Challenger Deep trough in the Mariana Trench near Micronesia.
NHS teacher studies offshore volcano
With another eruption imminent, scientists and a Teacher at Sea recently spent ten days studying underwater volcano Axial Seamount, focusing on re-inflation of magma chambers, and tracking undersea floor changes.
Scientists just found a surprising possible consequence from a very small amount of global warming
Even if we meet our most ambitious climate goal — keeping global temperatures within a strict 1.5 degrees Celsius (or 2.7 degree Fahrenheit) of their preindustrial levels — there will still be consequences, scientists say. And they’ll last for years after we stop emitting carbon dioxide into the atmosphere. New research suggests that extreme El Niño events — which can cause intense rainfall, flooding and other severe weather events in certain parts of the world — will occur more and more often as long as humans continue producing greenhouse gas emissions.
The Biggest Battle in Five Generations
Deaths of baby oysters in the Pacific Northwest are happening at an alarming rate because of increasing ocean acidification due to climate change. For shellfish farmers and the area that depends on them, it’s a more unwieldy foe than they’ve ever confronted.
