gigatons of melting ice and vanishing coral

its been a little while since my last posting here... here are a couple articles that stuck in my brain.

Ice melting across globe at accelerating rate, NASA says

In the past five years, Greenland has lost between 150 gigatons and 160 gigatons each year, (one gigaton equals one billion tons) or enough to raise global sea levels about .5 mm per year

measured that mountain glaciers in the Gulf of Alaska lost about 84 gigatons each year, about five times the average annual flow of the Colorado River through the Grand Canyon, according to NASA.

World's corals reefs are vanishing, report says

The world has lost almost one-fifth of its coral reefs according a new report released by the International Union for Conservation of Nature (IUCN).

It's not just climate change -- which raises ocean temperatures and increases seawater acidification -- which is damaging reefs. In some parts of the world overfishing, pollution and invasive species are proving equally harmful.

Scientists are warning that reef destruction will have alarming consequences for around 500 million people who rely on coral reefs for their livelihood.

Left unchecked, remaining reefs could be completely wiped out by 2050, the report says.

all i can say about these to articles is "this sakus".
