    It’s hard to imagine intentionally freezing a ship into the Arctic ice, but that’s just what researchers with the mission did. Over the course of a year, they’re compiling data on marine biology, meteorology and more.

    The German icebreaker Polarstern lit up on every deck, acting as a beacon for researchers navigating the Arctic terrain.

    Death Valley is known for its extreme dryness and dangerous heat records. However, traces on the land indicate that water sometimes flows here.

    A prototype of an ozone-monitoring instrument got its first look at the Sun this week. The Stratospheric Aerosol and Gas Experiment (SAGE) IV will use light from the rising or setting Sun to measure ozone and tiny particles known as aerosols.

    If you look at a map of sea level rise, you’ll find it’s not uniform around the globe. Although sea level rise affects coastal areas all over our planet, some regions feel its effects sooner and more severely than others. looks at “relative sea level" change ⬇️

    While sea level rise affects coastal areas everywhere, each region feels its effects differently. That's because when it comes to coastal sea level, it's all local, and it's all relative.

    Penned in by land masses, most ice that forms in the Arctic Ocean stays there for the duration of its existence—typically one to four years before melting. Some ice, however, escapes the Arctic Ocean through a handful of passages and then drifts south.

    Since the start of Asia’s summer monsoon season, excessive rainfall has pushed lakes and rivers to record high levels in . In these images, dam operators are trying to regulate the flow by discharging floodwater through spillway gates.

    In an early mission, famed aquanaut Jacques Cousteau and astronaut Russell Schweickart teamed up aboard the Calypso to measure water depths as 1 and 2 orbited overhead, paving the way for satellite bathymetry research.

    This natural-color Landsat 8 image acquired on March 23, 2019, shows where the northern Great Bahama Bank meets the deep ocean.

    This review of "climate sensitivity," or how much warming to expect with a change in carbon dioxide (CO2), determined that the planet will warm several degrees (about 4-8°F) when CO2 in the atmosphere is doubled. The study is available from here:

    More evidence comes from ’s MODIS instrument, which provides information about clouds. Understanding the role clouds play in reflecting & absorbing heat and how that might change in the future is important in understanding how much warming to expect.

    That evidence comes in part from missions like the CERES instrument, which measures Earth’s energy budget -- essentially, how much energy is coming in as absorbed sunlight versus how much is reflected or returned to space as heat.

    Researchers have long known that human activities are heating up the planet. But estimating how much future warming can be expected for a given increase in carbon dioxide has remained an area of active research. Scientists at helped with a new look at the evidence.
