Climate change Apr 16 Green isn't always good — especially in Antarctica Lew and Fritz collect small biopsies using a specially-designed crossbow which creates minimal impact on the whales.

They analyze the biopsies aboard the ship to understand the full weight of climate change on whales’ health — everything from rapidly melting sea ice to dwindling populations of krill, their food.

NOAA research shows it would take the average tree more than 1500 years to sequester the amount of carbon dioxide a whale can in a single year.
