what if the temperature raises by 1.5 degrees per year how long would we have before the oceans would rise and

Answer 1

Well I couldn't say for sure but it wouldn't be much. But that increase is way beyond any predicted by even the global warming fanatics. What is known is that the current sea levels are about 200 ft below the maximum estimated levels so they could naturally rise 200 ft above their current levels, as they have before. Which by the way was before there were SUV's or global warming fanatics.

Based on past history it is very unlikely that natural global warming will ever or has ever occurred at a rate anywhere near the 1.5 degrees per year. However, it is possible for the global temperature to decrease at a rate many times as fast. And that the normal cycle is for an ice age lasting around 100,000 years followed by global warming for around 10,0000 followed by another ice age. Its been 10,500 years since the last ice age and were over due.

Ice ages don't require centuries to happen. It simply snows one winter and doesn't melt. Then it snows on top of that the next winter. I'd be more concerned about that than 1 to 2 degree temperature increase over a century or two.

Answer 2

A billion years.
