Draft IPCC report predicts sea levels to rise a metre by end of century!

Sea levels could rise a metre by the end of the century, according to the latest report by the Intergovernmental Panel on Climate Change (IPCC).

The ABC has obtained a final draft of the report ahead of its official release next Friday.

While average land and sea temperatures will continue to rise, it shows the planet is heating at a slower rate.

The IPCC predicts anything more than 4 degrees Celsius is unlikely this century.

Professor Steve Sherwood from the University of New South Wales says the more immediate impacts of climate change are well known.

“Right now if you look at the rate of increase of carbon dioxide in the atmosphere, it is fairly close to the worst case scenarios that have been looked at by scientists since we started looking at this problem,” he said.


“Eventually we can expect to see more intense heatwaves, stronger downpours of rain, longer periods between rain.

“They are three things that a lot of different lines of evidence tell us that’s what we can expect in a warmer world.”

The scenarios outlined in the draft report show global temperatures have risen by almost a degree since the pre-industrial era.

The report suggests sea levels could surge by a metre by the end of the century, in part because glaciers and ice sheets are melting faster.

Evidence suggests that if carbon emissions keep rising, it would lead to a near complete loss of the Greenland ice sheet and a seven-metre sea level rise by the end of the millennium.

But one thing scientists have been battling to explain is why the rate of warming has slowed.

The draft report says the rate of warming over the past 15 years (1998-2012) is likely to have been 0.05 degrees, smaller than the trend since 1951 of 0.12 degrees.

John Cook from the Global Change Institute at The University of Queensland says the planet is still heating up.

“There’s been a lot of studies that have examined the question over the last few years and what the evidence seems to be telling us is the oceans are picking up most of the heat of global warming,” Mr Cook said.

Some who question the science have focused on the report’s apparent lack of certainty about exactly how our climate will change.

Scientists from around the world are due to gather in Stockholm next week to finalise the exact wording of the report – but the debate is likely to continue long after its release.


One Comment on “Draft IPCC report predicts sea levels to rise a metre by end of century!

  1. The IPPCC is always underestimating the projected impacts of Climate Change.
    It’s not well known that Sea level rises of over meter will occur by the end of the century regardless of weather we stop all carbon emissions or not due to reinforcement feedback loops in the earths climate system.
