Sea levels rose rapidly in past 150 years: Study

The study led by the Australian National University looked at the fluctuation of ocean levels over the past 35,000 years, based on ice volume changes around the world.
  
According to Professor Kurt Lambeck from ANU, sea levels were oscillating by no more than 20 centimetres over several millennia, ABC News reported.
  
"In the last 6,000 years before the modern onset of sea level rise, the sea level has been quite stable," he said.
  
"We see no evidence for oscillations in sea level greater than say plus or minus 25 or 30 centimeters, on timescales of 100 years or longer there's just no evidence for that," said Lambeck.
  
However, he said there has been a rapid upward trend accompanying global industrialization.
  
"For the last 150 years we've been seeing this increase, this rising sea level, at a rate of a few millimeters per year and in our older records we do not see similar behaviour," he said.
  
Lambeck said comparing the historical data with recent data from tidal gauges shows an increasing rate of sea level rise in recent times.
  
"What we see in the tide gauges we don't see in the past record, so there's something going on today that wasn't going on before. I think that is clearly the impact of rising temperatures," said Lambeck.
  
He said increasing temperatures have been documented to have clear effects on sea levels.

Break-ups quite common among same-sex couples: Study

The study also found that same-sex couples with a marriage-like commitment in US have stable unions regardless of government recognition.

The findings come from a nationally representative survey of 3,009 couples (471 same-sex) who were followed between 2009 and 2013.

"The marriage commitment is associated with a strong benefit in couple stability for both heterosexual couples and same-sex couples," said lead author Michael J Rosenfeld.

For the study, researchers explored a variety of predictors of relationship dissolution for heterosexual and for same-sex couples.

They also found that longer duration of unmarried couplehood drives down the annual break-up rate but only up to a point.

"Married couples are dramatically more likely to stay together than unmarried couples at all levels of relationship quality and at all relationship durations," Rosenfeld noted.

The study appeared in the Journal of Marriage and Family.
