Melting ice in the Arctic Ocean will drastically reduce journey times for sea travel and other trade routes.
The study of benthic animals from the Toracian seems to suggest that they have become smaller and smaller as temperatures have risen. It's not impossible that this is happening with current warming.
A new study by the Woods Hole Oceanographic Institution (WHOI) shows that the efficiency of the Ocean's biological carbon pump has been massively underestimated, with major implications for future climate assessments.
A decline in plankton and carbon fluxes along the Western Antarctic Peninsula has been observed, correlated with the reduction in ice extent.

Carpets of fleshy (mat-like) red algae form in the Mediterranean and Atlantic. They appear to be substitute habitats for fixed invertebrate animals during major climatic changes.
With the arrival of El Niño, stronger marine heat waves will appear. Researchers need to help governments plan how best to reduce the risks.
The study of past climates is an important tool for understanding and anticipating future climate change. Here, ocean levels during the last Ice Age are studied on fossil reefs in Australia.
The general negative effect of marine heat waves on ecosystems has not always been verified. Despite general effects on biomass, the mechanisms are still relatively poorly understood for demersal fish.
This year marks the halfway point in the implementation of the UN's Agenda 2030 for Sustainable Development and its 17 Sustainable Development Goals, including Sustainable Development Goal 14 ("Life Below Water").
Intense cyclones leading to extreme weather and climate events in the Arctic have been observed more frequently in recent years, causing dramatic environmental and socio-economic impacts.
"Electronics engineer Axel Bres predicts the weather on one of the world's most isolated islands, at Port-aux-Français, a French scientific base in the sub-Antarctic archipelago of Kerguelen."
Droughts in the Amazon are becoming increasingly frequent and intense. According to scientists, a critical threshold could be reached very soon. A link with El Nino oscillations is being put forward.
According to the estimates of many scientists, major climatic disasters in the United States occur every three weeks. Many of these disasters are water-related: droughts, floods and changing ocean climates.
A vast study and several expeditions point the finger at the effects of a 2°C rise in ocean temperature. Here, a concrete example of the Carpet Sole migrating north. The effects on food chains could be very negative.
Marine heat waves are extreme events that can have devastating impacts on ecosystems and the economy. Today, only surface phenomena are detected. Yet there are many such phenomena at depth.
Limiting global warming to below 2°C (as recommended by the IPCC) would preserve habitat conditions in the Mediterranean for many fish. Tuna, for example, would see little change in their reproductive capacity.
The study of sedimentary and glacial plankton enables us to reconstruct past climates. Strong temperature gradients during the Ice Age in the North Atlantic Ocean have been revealed in this way. Understanding past climate means anticipating future climate.
