The Mudd

Hi again, Mike. 👋 Let’s go over this for what’s now a third time. Maybe it will sink in. The Greenland ice sheet contains about 2.9 million gigatons (Gt) of ice. 🧊 Using the conversion factor that 1 Gt = 1 billion tons, this means that the ice sheet has roughly 2.9 million billion tons of ice. Oh yes, math is involved!! Now, if the ice sheet is losing 30 million tons of ice per hour, that would work out to 720 million tons of ice lost per day and a net 262.8 billion tons per year. 🫠 Here’s the math, 🫳 -30 million tons × 24 hr. (1 day) × 365 days (1 year) = -262.8 billion tons / year 262.8 billion tons of ice lost per year? Oh my, that sounds scary! 😱 That is, of course, until you realize that at the current rate, it would take more than 11,035 years for the entire Greenland ice sheet to melt. 🏔️ ➡️ ⛰️ = >10 millennia Let’s do more math to confirm this. 2.9 million billion tons / (262.8 billion tons / year) ≈ 11,035 years. Now, what would this mean for sea level rise (SLR)? 🌊 Well, according to NASA, for every 360 Gt (or 360 billion tons) of ice lost, the global average sea level rises by about 1 millimeter (mm). 🔗 sealevel.nasa.gov/understand…… If 262.8 billion tons of ice is lost per year, that would mean sea level rises at a rate of 0.73 mm (~0.03 in) / year from loss of Greenland ice alone. 📏 Ignoring Antarctica, this would cause the global average sea level to rise about 1 ft. every ~417.5 years. Now, the rate of ice loss could accelerate or decelerate depending on other factors (e.g., natural variability or positive / negative climate feedbacks), but it’s clear from these back of the envelope calculations that you are hyperventilating over nothing. This is a very manageable problem. So is your climate anxiety. Just stop parroting WEF propaganda and go touch grass.
