climate change consequences

- warming oceans, melting glaciers melting, rising sea level

Pine Island Glacier's ice shelf is ripping apart, speeding up key Antarctic glacier,  June 11, 2021, by University of Washington

For decades, the ice shelf helping to hold back one of the fastest-moving glaciers in Antarctica has gradually thinned. Analysis of satellite images reveals a more dramatic process in recent years: From 2017 to 2020, large icebergs at the ice shelf's edge broke off, and the glacier sped up.

These glaciers [Pine Island Glacier and Thwaites Glacier] have attracted attention in recent decades as their ice shelves thinned because warmer ocean currents melted the ice's underside. From the 1990s to 2009, Pine Island Glacier's motion toward the sea accelerated from 2.5 kilometers per year to 4 kilometers per year (1.5 miles per year to 2.5 miles per year). The glacier's speed then stabilized for almost a decade.

[ short term consequences]
Coastal roads, railways, ports, tunnels, and airports are vulnerable to sea level rise, which could lead to delays as well as temporary and permanent closures.

[ middle term consequences]
Climate change is likely to damage transportation infrastructure through higher temperatures, more severe storms and flooding, and higher storm surges, affecting the reliability and capacity of transportation systems.

[ long term consequences]

Climate change impacts will likely increase the cost of the nation’s transportation systems.
