Polar vortexes, increased heat waves, and unpredictability of weather caused by ice loss are already causing significant damage to crops on which global food systems depend. This instability will continue to mean higher prices for you and growing crises for the world’s most vulnerable.
As ice melts, new shipping routes open up in the Arctic. These routes will be tempting time-savers, but incredibly dangerous. Imagine more shipwrecks or oil spills like the Exxon-Valdez in areas that are inaccessible to rescue or clean-up crews.
When there’s less sea ice, animals that depend on it for survival must adapt or perish. Loss of ice and melting permafrost spells trouble for polar bears, walruses, arctic foxes, snowy owls, reindeer, and many other species. As they are affected, so too are the other species that depend on them, in addition to people. Wildlife and people are coming into more frequent contact – and often conflict – as wildlife encroach on Arctic communities, looking for refuge as their sea ice habitat disappears.
Arctic ice and permafrost—ground that is permanently frozen—store large amounts of methane, a greenhouse gas that contributes to climate change. When it thaws, that methane is released, increasing the rate of warming. This, in turn, causes more ice and permafrost to thaw or melt, releasing more methane, causing more melting. As we lose more ice more quickly and see more rapid permafrost melt, we will start seeing the worst climate change predictions come true.
