It is believed by many environmental experts that if global warming continues at the current rate, our planet will undergo dramatic changes in the next 1000 years. And one of the major problems we will face is the rise in sea level.
And the terrifying impacts of sea level rise include the obvious consequence of flood disasters, contaminated drinking water as the sea seeps into the freshwater sources in the ground, problems with agriculture and infected crops, threatened wildlife populations and a damaged economy (particularly due to coastal tourism being affected).
So despite the recent controversy claiming that some climate models may be wrong or inaccurate, global warming is still very much an urgent topic. And one that world leaders need to take seriously.
Efforts such as offshore wind farming and renewable energy incentives for homeowners and businesses are key ingredients in our fight against climate change. And as technology advances and expertise grows in these areas, we should be able to establish viable sources of energy that are no longer harmful to our environment.
Primary Factors of Sea Level Rise
There are three primary factors of sea level rise, all induced by the impacts of global warming. These have all contributed to sea level rise of 80 mm in just the last 13 years.
As water heats, it expands and more than half of the past century’s sea level rise has been caused by this phenomenon. Our oceans simply need to occupy more space as the earth gets hotter.
Polar ice caps and other ice formations naturally melt back in the summer, whilst the cold winters are enough to replenish and rebalance the melting. But with persistent high temperatures creating later winters and earlier springs, we are now faced with higher levels of glacier and polar ice melting than before.
Ice loss from Greenland and West Antarctica has been one of the biggest problems, with massive ice sheets melting down at an accelerated pace. Scientists also believe meltwater from above and seawater from below is seeping beneath Greenland’s and West Antarctica’s ice sheets, causing ice streams that break off and move quickly into the sea.
