Over 100 million buildings worldwide could face flooding risk from rising seas, study warns

A group of international researchers believe the collapse of the West Antarctic Ice Sheet (WAIS) which is projected to lose mass due to climate change and global ocean warming and is likely to contribute to the rise in sea levels impacting coastal communities across the world is preventable.

The researchers are part of a project which is an international collaboration involving scientists, drillers, engineers and science communicators known as the “Sensitivity of the West Antarctic Ice Sheet to Two Degrees of Warming” or SWAIS2C.&nbsp;

<h2>‘We may have some time’</h2>

Researchers citing a recent ice sheet modelling wrote in The Conversation, that all is not lost since Ross and Ronne-Filchner – Earth’s largest ice shelves currently stabilise large regions of ice in the West Antarctic interior – are still intact.&nbsp;

While there are ocean cavities beneath ice shelves that are already “warm”, there are also regions where ice shelf cavities are currently ‘cold’,&nbsp;the group of researchers and scientists wrote.&nbsp;

Therefore, based on existing data they believe that these large ice shelves and the WAIS will largely remain intact if we manage to keep warming close to or below two degrees Celsius above pre-industrial level.

The modelling experiments, according to the researchers, indicate that if the 1.5 degree Celsius threshold, set under the 2015 Paris climate agreement, is not crossed it can limit the total contribution to sea level rise coming from the Antarctic ice sheet to somewhere between 0.12-0.44 metres by 2100.&nbsp;

However, since global surface temperature is likely to exceed the 1.5-degree threshold, the melting of the ice sheet could raise global sea levels by as much as three metres. The WAIS is said to be Antarctica’s largest current contributor to global sea-level rise.&nbsp;

They also noted that the collapse of the WAIS could have devastating consequences, including widespread flooding and displacement of coastal communities.&nbsp;

<h2>Addressing the knowledge gap</h2>

The SWAIS2C project, according to their website, aims to answer the key question ‘Does the Paris climate target save the Ross Ice Shelf and limit Antarctic Ice Sheet melt’?&nbsp;

In a bid to look for the answer, their team will recover “key environmental information from the ice and sediment” at two different sites on the Ross Ice Shelf.&nbsp;

So far, no one has drilled deep into the Antarctic seabed, particularly at a location so far from a major base and so close to the centre of the WAIS.&nbsp;

The team, according to the project’s website, will drill through thousands of feet of ice at two different sites – Kamb Ice Stream and Crary Ice Rise – to recover “sediment cores”.

The drilling would also allow them to collect and compare data on how the ice shelf behaves in different temperatures to understand how sensitive the Ross Ice Shelf and WAIS were to past warming similar to the 1.5 to two degrees Celsius set in the Paris Agreement.

Researchers believe the collapse of West Antarctic ice sheet is preventable: Report

Climate change is real. The excessive use of fossil fuels, deforestation and other issues have led to the rise in the temperature of the Earth. It is in turn leading to melting of glaciers, rise in sea level, etc. The worst sufferers of climate change will be coastal areas as they will face sinking due to the spike in the level of sea water. But can anything be done to stop it? Well, absolutely, the world can actually fight sea level rise. If you are wondering how, keep reading. &nbsp;

Build seawalls &nbsp;

To keep a check on the rise in sea level, seawalls can be constructed in coastal areas to ensure the sea water does not flood it. Although it can get a little expensive, it will be a must in the future. The rise in the temperature of the Earth is continuing and several coastal areas may witness flooding in the coming years. Some Hollywood flicks have already shown a glimpse of how seawalls can stop sea water flooding. Not just this, Japan has already built them in some areas.&nbsp;

Use beaches as natural barriers &nbsp;

The beaches can also be used as a natural wall to negate the impact of the sea level rise. Big beaches or large dunes can help in stopping water from reaching homes and roads. This may be of great help in future. &nbsp; &nbsp;&nbsp;

Install&nbsp;stormwater pumps &nbsp;

Big stormwater pumps can be installed and used to suck sea water in case of flooding. It may come in handy if sea storms cause flooding. &nbsp;

Raise level of&nbsp;roads&nbsp; &nbsp;

The level of roads can also be raised to ensure that it doesn’t become a victim of sea water flooding. It may bring respite.

Upgrade sewage systems &nbsp;

It will also be a must to upgrade the sewage systems as they may be needed to hold large quantities of sea water if flooding ever happens.&nbsp;&nbsp;
