Greenland has been melting faster in the last decade, and this summer, it has seen two of the biggest melts on record since 2012. A special United Nations-affiliated oceans and ice report released on Wednesday, Sept. 24, 2019 projects three feet of rising seas by the end of the century, much fewer fish, weakening ocean currents, even less snow and ice, and nastier hurricanes, caused by climate change.

Airbnb is offering a handful of tourists concerned about the environment a chance to help participate in scientific research on how to help preserve it with an all-expense paid trip to Antarctica. The Antarctic Sabbatical, as the travel company is dubbing it, will give five people the opportunity to study how widely micro plastics have infiltrated the region. Over a month’s time in December, they’ll be trained in lab work in Chile, collect snow samples in Antarctica, climb key glaciers and even visit the South Pole. (AP Photo/Natacha Pisarenko, File)

This June 2018 photo provided by Rob McClelland shows Allie Kurtz aboard a sailboat. Kurtz, a 26-year-old scuba diving boat crewmember who loved the ocean and had just landed her dream job, is among multiple victims of a deadly fire that torched a dive boat off Southern California's coast, her family said on Wednesday, Sept. 4, 2019. Kurtz recently left a job in movie promotion with Paramount to follow her heart and work on the sea, said her grandmother, Doris Lapporte. (Rob McClelland via AP)

Federal scientists say they're monitoring a new ocean heat wave off the West Coast. Researchers with the National Oceanic and Atmospheric Administration said Thursday, Sept. 5, 2019, the expanse of unusually warm water stretches from Alaska to California, and it resembles a similar heatwave that disrupted marine life five years ago. It remains to be seen whether this heat wave will linger or dissipate more quickly than the last one. (AP Photo/Elaine Thompson, File)

FBI investigators unload equipment to begin examining evidence obtained from the wreckage of the dive boat Conception on Wednesday, Sept. 4, 2019, in Santa Barbara, Calif.
