On 25 February 2018 at 17:44 UTC, a 7.5 magnitude earthquake rocked Papua New Guinea with its epicentre 83 km southwest of Porgera, in Hela province.

Earth may be the "Blue Planet", with more than 70 percent of its surface covered in water, but it is still a thirsty planet, with freshwater in heavy demand. The most significant draw on the water supply is crop irrigation, accounting by some measures for nearly two-thirds of U.S. surface-freshwater withdrawals.

The information provided by the Copernicus Climate Change Service (C3S) and the Copernicus Atmosphere Monitoring Service (CAMS) was used to develop the European State of the Climate 2017 report, an important step forward towards a better understanding and assessment of the state and the indicators of our changing climate.
Last spring, NASA researchers flew over the Everglades and Puerto Rico to measure how mangroves and rainforests grow and evolve over time. Five months later, hurricanes Irma and Maria tore through those study areas – creating a unique opportunity to investigate the devastating effects of massive storms on these ecosystems, as well as their gradual recovery.
Last year was a record year for wildfires across the globe, and their impact on the atmosphere remains highly uncertain. Thanks to new research from expert scientists at the U.S. Naval Research Laboratory, the world is gaining more insight into what drives these massive and escalating events.

A new study reveals that low-frequency electromagnetic waves accompany intense heating events at low altitudes.

ESA's CryoSat mission has revealed that, over the last seven years, Antarctica has lost an area of underwater ice the size of Greater London. This is because warm ocean water beneath the continent's floating margins is eating away at the ice attached to the seabed.
Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.
For the first time, scientists can look at landslide threats anywhere around the world in near real-time, thanks to satellite data and a new model developed by NASA.
Scientists propose development of new models that use machine learning techniques to reduce uncertainties in climate predictions.

The traditional way of mapping Earth's geology and mineral resources is a costly and time-consuming undertaking. While satellites cannot entirely replace the expert in the field, they can certainly help – as a recent effort in Africa shows.
More Arctic sea ice is entering the North Atlantic Ocean than before, making it increasingly dangerous for ships to navigate those waters in late spring, according to new research.
The millions of tonnes of plastic ending up in the oceans every year are a global challenge. ESA is responding by looking at the detection of marine plastic litter from space, potentially charting its highest concentrations and understanding the gigantic scale of the problem.

Steve – a strange shimmering ribbon of purple light in the night sky – was discovered in 2016, but now, thanks to ESA's Swarm mission, more is known about this weird feature of the aurora.
Global climate is a tremendously complex phenomenon, and researchers are making painstaking progress, year by year, to try to develop ever more accurate models.

NOAA's Geostationary Operational Environmental Satellite (GOES) constellation monitors Earth's environment, helping meteorologists observe and predict the weather.
Clouds play a prominent role in moderating Earth's climate, but their role is still poorly understood. Generally, clouds cool the Earth by reflecting incoming sunlight back out into space. Reducing the cloud's reflectivity - with a layer of pollution, for example - reduces the cooling effect. New research suggests that smoke from fires may be counteracting this effect by making clouds more reflective.
The United States filled a crucial gap in its weather-forecasting arsenal when it launched its latest geostationary satellite on 01 March. The craft will enable meteorologists to track hurricanes, snow storms and other threats as they develop. It will also beam down data that researchers can use to measure air temperature and humidity — if they can work out how to incorporate them into their models.

It's another demonstration of the power of Big Data - of mining a huge batch of statistics to see patterns of behaviour that were simply not apparent before.

A NASA study based on an innovative technique for crunching torrents of satellite data provides the clearest picture yet of changes in Antarctic ice flow into the ocean. The findings confirm accelerating ice losses from the West Antarctic Ice Sheet and reveal surprisingly steady rates of flow from its much larger neighbour to the east.
