How long is blue ocean event?

Global climate models have long been conservative in predicting the demise of Arctic ice. On average, they’ve tended to produce a blue ocean event no sooner than 2040, and often not until late this century.

What is a BOE event?

Climatologist Paul Beckwith is very concerned about the Blue Ocean Event (BOE). As usual, new ice, which is frozen ocean water, will grow in the winter and melt in the summer. But since it is melting so fast it doesn’t last from year to year. As sea ice survives through several melt seasons, its characteristics change.

When was the Arctic last ice-free?

In July of 2020, the area covered by sea ice in the Arctic Ocean reached a new low for the month. With record warming caused by human activity, the Northern Sea Route became ice-free earlier than previously recorded. At the end of July, Canada’s last intact ice-shelf collapsed.

What is boe Arctic?

As Arctic sea ice gets thinner and thinner, what some have dubbed a ‘Blue Ocean Event, (BOE)’ [2] looks more imminent every year. Generally, scientists define an ice-free Arctic as a complete absence of Arctic sea ice (a common threshold is when the area is less than 1 million sq. km.).

What would happen if Arctic melts?

Sea levels will be drastically affected. The disappearing ice in the Arctic affects more than just the surrounding area. “If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities.

What are the consequences of the disappearance of Arctic sea ice?

The continued loss of Arctic sea ice will include further Arctic warming, erosion of Arctic coastlines, and a disturbance of global weather patterns. Sea ice loss will also open up the Arctic to increased human activity, further disturbing Arctic communities and ecosystems.

What is included in a BEO?

A BEO should include all food and beverage details such as: Menu – All menu items should be listed in the order in which they will be served, including optional children’s meals….What Should a BEO Include?

• Contact info.
• Space usage.
• Event date.
• Set-up and start/end times.
• Number of guests.

What are the consequences of ice melting?

Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.

What are the direct effects in the Arctic of the Arctic warming?

Without urgent action to cut greenhouse gas emissions, the world will continue to feel the effects of a warming Arctic: rising sea levels, changes in climate and precipitation patterns, increasing severe weather events, and loss of fish stocks, birds and marine mammals.
