An adult male polar bear can lose or gain up to 60 kilograms of body weight within just a few days - an amount equivalent to the body weight of an average adult human.
From 25 to 27 February 2026, the Monaco Polar Symposium will bring together leading scientists, political decision-makers, and institutions at the Oceanographic Museum of Monaco.

A drone experiment over the Greenland ice sheet has made it possible for the first time to take detailed measurements of water vapor in the atmosphere over Greenland. This new technology could contribute to improving climate models and help to better estimate Greenland's future contribution to global sea level rise.

From mapping fjords to studying particles, the Forel research vessel leads multidisciplinary expeditions in the Arctic to better understand the impact of global warming and marine ecosystems. A true floating laboratory that looks like a Swiss Army knife.
On Bylot Island in the Canadian Arctic, bodies of ice have been hidden in the permafrost since the early Pleistocene – well protected from external influences and several warm periods. The age of the ice is estimated to be more than 770,000 years.
Male sperm whales in the North Atlantic spend much of the year in Arctic waters, migrating south only for mating. For the first time, a research team has demonstrated that these migrations do not follow a fixed schedule.
Whales are considered the ecosystem engineers of the oceans. They stimulate the growth of phytoplankton, which in turn supports the growth of their primary food source, krill.
Diatoms, a key player in the Southern Ocean food web, may contribute less to the biological carbon pump than previously thought.
The sea ice cover of the Arctic Ocean has not only shrunk and thinned due to global warming but has also become significantly flatter over the past three decades.
Plastic pollution in the Southern Ocean may hinder the efficient transport of carbon bound by Antarctic krill to the deep ocean, with implications for the global carbon cycle and thus for global warming.
