Are sea levels rising

Answer 1

Yes, sea levels are rising. In the past few years sea levels have been measured rising an average of about 3 mm every year (.12 inches). Sea levels are measured using a combination of tide gauges and satellite radar altimeter data. A Glacial Isostatic Adjustment model is used to correct for any movements in the land.

In 2007 the UN Intergovernmental Panel on Climate Change (IPCC) put the projected sea level rise as 59 cm (23 inches) by the year 2100. It agreed that many researchers thought this was a conservative figure.

Australia's Department of Climate Change and Energy Efficiency reported in 2009: "There is growing consensus in the science community that sea-level rise at the upper end of the IPCC estimates is plausible by the end of this century [2100], and that a rise of more than 1.0 metre and as high as 1.5 metres cannot be ruled out". (3 feet to 5 feet)

In 2011 Norway's Arctic Monitoring and Assessment Program found that the Greenland ice sheet is melting four times faster than it was ten years ago. It reported:

"The past six years have been the warmest period ever recorded in the Arctic. In the future, global sea level is projected to rise by 0.9 metres to 1.6 metres by 2100 and the loss of ice from Arctic glaciers, ice caps and the Greenland ice sheet will make a substantial contribution."

Each centimeter of sea-level rise roughly translates to one meter of beach erosion, meaning that the coastline can be expected to more 160 meters (174 yards) inland.

A:A peer-reviewed study published in 2009 titled "A new assessment of the error budget of global mean seal level rate estimated by satellite altimetry over 1993-2008" suggests that there has been an observed reduction in the prior rate of sea level rise by 2mm/yr from 2005 (a 60% reduction from the 1993 to 2005 rate) to a level of 1mm/yr. Some climateologists expect sea level rises to plateau around 2050.

The IPCC was forced to withdraw its 2007 prediction regarding sea level rises due to "two technical errors" in its calculations.

A report published in 2009 by Dr Mark Siddall from the Earth Sciences Department at the University of Bristol (together with colleagues from Switzerland and the US) indicated a rise in sea levels of between 7cm and 82cm over the next century based on "best case" and "worst case" scenarios (best case being a rise in global temperatures of 1.1oC, worst case being a rise in global temperatures of 6.4oC.

Answer 2

that is the rise of sea by melting ice, through which happens due to global warming also known as climate change.

Answer 3

Exactly that.. The water is getting higher on the shores due to ice caps melting.

well kinda but really just water is getting higher

Answer 4

Tide
