3. A floating flipped iceberg in the Weddell Sea, off Argentina, with a block of green sea ice now showing above the water, joined to the whiter land ice. This picture was taken from the British research vessel RRS Discovery on a research cruise in the Southern Ocean in the Weddell Sea. The Ocean Frontier Institute says the ocean is the main climate actor and needs this acknowledgment. Credit: David Menzel/Climate Visuals
