Spot on David. Without two centuries of fossil fuels forcing warming into our biosphere, the planet would be ever so slowly shifting to a slight cooling phase. And Exxon and Chevron knew they were the cause of #climate warming many decades ago. #climatechangeisreal #ActOnClimate

Hmmm. Is he signaling that he is going to crash the US economy? Then will he restart it without the US Dollar and instead institute a crypto-based economy?

From paddling Minnesota’s pristine Boundary Waters to disrupting the migratory patterns of 200,000 Porcupine Caribou in our Arctic Refuge, it’s wilderness protection, public lands and recreation vs Big Oil and extraction. Pick a side. The battle is on. #ProtectPublicLands and #Wilderness #Arctic
Please read my in depth story on Substack where I go into further depth on the threats to our public lands and the Arctic National Wildlife Refuge including a side trip on a documentary photo mission into the ancient Gwich'in village of Old Crow Yukon. https://thoreson.substack.com/p/red-alert-your-public-lands-are-under

Melissa has now gone through 2 rapid intensifications with winds at 185 mph (gusting 215+) n a low pressure reading of 992 mb, making this the 3rd strongest hurricane recorded in the Atlantic Ocean system. Storm surge 9-13 feet w heavy rain n high tide conditions. Worst case scenario for Jamaica.

Less #Seaice in the Arctic means more shipping in the Northern Sea Route, which Putin controls. Until the USA understands climate disruption, we are at a strategic disadvantage.

Thx Zack. Multi-year thick sea ice is near extinction in the Arctic. Sea ice extent is like the skin of an onion, lots of thin first-year ice. The #NorthwestPassage was again open this season.

Been there. Seen it. Groundtruthed the science multiple times. We’re losing sea ice quickly in the North.

16 years ago, I was the photographer and ice sailing expert on Ocean Watch sailing through the #NorthwestPassage from west to east. I shot this image near Bellot Strait as we were putting the passage behind us. Now a new One Ocean #sailing voyage is retracing our route to document enviro change.
Ocean Watch sails through the Northwest Passage in 2009 on a 28,000-mile circumnavigation of the Americas. Seattle to Seattle. Now a new circumnavigation is underway with the same captain Mark Schrader retracing our voyage and doing scientific research along the way.

Trump and his science-denying thugs are wiping climate change data from the system. They are willing to burn 🔥 the USA and civilization to the ground. The #climatecrisis is real and life threatening. This shit is real folks and the fossil fuel industry doesn’t want you to have the data anymore.

We left Mexico from Barra de Navidad n headed west and slightly south, #sailing 3000 miles now across the Pacific Ocean on a 47' sailboat named Polar Sun. We went through the Northwest Passage and were the cover of Nat Geo in 2023. Awesome days on the #ocean. #Photography #Drone #landscape #explore

Happy Earth Day 🌎 everyone from the Pacific #Ocean. Celebrate the the magic to be found in nature. This lovely home planet is 70% water and it’s all threatened, our oceans and freshwater systems. Let’s all work hard in our own watersheds and support conservation and climate efforts as we can.

Sailing and climate meet at the equator. As we sail across the Pacific in the NE trade winds it’s important to note these NE/SE trades force air into the convergence zone at the equator where it’s heated, lifted and redistributed back towards the poles. Our very own unique #climate system. #Nature

We are now officially at sea! That’s the last land we’ll see for the next 3000 miles as we now sail from the western Mexico coast to the French Marquesas Islands. I’ll be posting along the way. Cheers mates!! #Sailing #Ocean #Photography
