Time and time again, we’ve been told that decisions we make regarding pollution will have major repercussions in the coming decades.<\/p>\n

But a study has found that those decisions will also have long-lasting impacts, particularly on sea-level rise.<\/p>\n

What’s happening?<\/p>\n

Researchers from the International Institute for Applied Systems Analysis modeled<\/a> what could happen to sea levels in hundreds of years, based on various emissions projections.<\/p>\n

They found that if current environmental policies continue, the heat-trapping pollution from 2020 through 2050 would lock in an additional 1 foot of sea-level rise by 2300. If that level of pollution continues through 2090, that would lock in a rise of more than 2.6 feet.<\/p>\n

The results were published in the journal Nature Climate Change<\/a>.<\/p>\n

“Our study shows clearly that mitigation decisions in the next few decades will have multi-century consequences for coastlines worldwide,” study author Alexander Nauels said<\/a>.<\/p>\n

Why is this study concerning?<\/p>\n

Pollution produced by burning dirty fuels<\/a> has led to considerable global temperature increases. Thermometer readings have risen so much that the past decade has seen the 10 hottest years on record<\/a>.<\/p>\n

Those warmer temperatures cause sea levels to rise for two key reasons<\/a>. First, glaciers and other polar ice melt, sending more water rushing into the oceans. Second, ocean water expands as it becomes warmer, causing an additional rise.<\/p>\n

That rise has intensified<\/a> in recent years, with the rate doubling since 1993. Researchers fear that could eventually put coastal communities at risk<\/a>.<\/p>\n

For example, the amount of sea-level rise projected by IIASA researchers would be enough to submerge some islands and other low-lying areas, or at least make them uninhabitable.<\/p>\n

What’s being done about rising sea levels?<\/p>\n

Some level of sea-level rise appears to already be locked in, the study revealed. But not all hope is lost for future generations.<\/p>\n

With significant policy changes and a steep cut in planet-warming pollution<\/a>, the amount of rise could vary significantly.\u00a0<\/p>\n

The researchers specifically cited the Paris Agreement<\/a>, noting that if countries reduce pollution to levels set out in that binding document, roughly 2 feet of sea-level rise could be avoided.<\/p>\n

“The difference between decisive climate action today and continued high emissions is not just measured in degrees of warming but also in meters of sea-level rise that will reshape coasts worldwide for centuries,” Nauels said<\/a>.\u00a0<\/p>\n

“Importantly, we show that we still have the opportunity to limit the sea-level rise commitment we pass on to future generations.”<\/p>\n
