NASA scientists estimate Greenland alone could cause 3-to-4 feet of sea level rise by 2100.

80 years. This is approx. one persons lifespan. So a babe born today==add 80years and he/she would actually see the rise --year by year. [if he or she lived by the ocean. ]



CLIMATE IN CRISIS: This summer has brought record-breaking heat and ice melt of Greenland’s ice sheet.

From what I have read, it is not only the increase in volume, but the expansion of the water from the rise in temperature that will inevitably help flood all coastal regions. It is called thermal expansion. That's double trouble.

Changes in atmospheric temperatures directly lead to increases and decreases in the temperature of the oceans. If the average global temperature rises so will the average temperature of our oceans.

Between 1993 and 2010 the rate of global mean sea level rise was 3.2 mm per year.3 Thermal expansion of the oceans accounts for 34% of that, at a rate of 1.1 mm per year.4

Due to the large heat capacity of the ocean and amount of time it takes for water to circulate there is a delay before the full effects of warming can be seen. This also means that there would be a delay between a reduction in atmospheric temperature and the cooling of the oceans.

Tokarska and Zickfeld modeled sea level response to several scenarios of atmospheric CO2 concentrations.5 They found that even when large amounts of CO2 are artificially removed, it would take several centuries for global mean thermosteric sea levels to decline.

And every grandparent I've had lived or is still living to their late 80's to mid-90's.

If she lives as long as the rest of my family, she'll live to see this.

Anyone have advice on how to tell my daughter not to have children and not break her heart when she's older?
