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.

Thermal Expansion

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.

Melting Glaciers

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

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.

Up to Date Measurements by NASA

For accurate information and data on sea level rise (as observed by satellites), visit the Nasa website. The site offers real time recordings of the sea level, showing a graph which has tracked the changes since 1993 until the present day.

  1. The current levels of CO2 indicate eventual sea levels 70 ft – 90 ft deeper than today, since the Pliocene 3.5 mya was the last time CO2 levels were this high.
    The seaports of 2000 years ago, like Alexandria, London, and Athens will all be underwater in 1000 years, if not much sooner.
    The sea level rise to 2100 is just the slow beginning. The pace of sea level rise will accelerate in the next few centuries.
    Since we will see CO2 levels over 600ppm, which as not been seen since the dinosaurs roamed and NO ice existed on Earth, sea levels could get much deeper. If we return to an ice free Earth, like in the Cretaceous, then the Earth oceans could get 200 ft deeper.
    That would be Florida and the Gulf coast underwater. Eastern China underwater. Most of Iraq underwater. Bangladesh — gone totally.
    The Sacramento Valley in California becomes an inland sea.
