What We Do Now Will Define the Oceans and Cryosphere of the Future

A new IPCC Special Report on the Ocean and Cryosphere claims that we still have time to avert some of the worst effects of climate change. Although painting a dire picture, which reveals the pervasive effects of global warming, the Report also highlights the significant benefits of limiting global warming by emphasising how lower emission scenarios will have reduced impacts on the wellbeing of oceans and the cryosphere.

Not Just a Science Experiment

Promoting ocean science policy and management for sustainable development is the core focus of the Ocean Decade. In the next few years, ocean stakeholders worldwide will gather behind a common framework that will ensure ocean science can fully support countries in creating improved conditions for the sustainable development of the ocean.

The Relationship Between Extreme Weather and Climate Change

Extreme weather is becoming increasingly common. Most recently, a record breaking heatwave in Greenland has gone viral thanks to the image of sled dogs wading through water where there should be ice. However, relating single weather events to climate change is problematic and, although these instances can act as indicators of a trend and eye-openers for public opinion, it is important to distinguish between single weather events and climate change.

Emperor Penguins Treading on Thin Ice

Climate change is drastically altering the weather patterns and ice conditions that enable emperor penguins, the icons of the Antarctic, to reproduce. The Halley Bay colony, the second largest in the world, in the Weddell Sea has failed to raise chicks for the last three years, leading to discussions on how to monitor climate change and the ability of animals to adapt in a changing world.

In the Glacier’s Belly

“Thwaites glacier is huge and contains vast amounts of ice above sea level that, if transported into the ocean, would affect global sea level significantly” researcher Dorotea Iovino on retreat and ice melt in West Antarctica. A NASA-led study has found that a giant, growing cavern two-thirds the area of Manhattan is contributing to the rapid melting of Antarctica’s Thwaites Glacier.

Arctic Report Card 2018: effects of persistent Arctic warming continue to mount

Continued warming of the Arctic atmosphere and ocean are driving broad change in the environmental system in predicted and, also, unexpected ways. New emerging threats are taking form and highlighting the level of uncertainty in the breadth of environmental change that is to come. A report tracking sea ice, snow cover, air temperature, ocean temperature, the Greenland ice sheet, vegetation and ecosystem changes during the 2018 calendar year.
