Air pollution is a global environmental health problem, especially for those living in urban areas. Not only does it negatively impact our ecosystems, it considerably affects our health. According to the World Health Organization (WHO), around 8 million premature deaths per year are linked to air pollution, more than double of previous estimates.
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth's surface. Ground that has been frozen for thousands of years is also thawing, adding to the climate crisis and causing immediate problems for local communities.

Our oceans and the complex "conveyer belt" system of currents that connects them play an important role in regulating global climate. The oceans store heat from the Sun, and ocean currents transport that heat from the tropics to the poles. They release the heat and moisture into the air, which moderates climate nearby. But what happens if part of that conveyer belt jams?

Almost a quarter of the West Antarctic Ice Sheet can now be considered unstable, according to a new assessment of 25 years of satellite data.
By unstable, scientists mean more ice is being lost from the region than is being replenished through snowfall.

As our climate changes, the availability of freshwater is a growing issue for many people around the world. Understanding the water cycle and how the climate and human usage is causing shifts in natural cycling processes is vital to safeguarding supplies. While numerous satellites measure individual components of the water cycle, it has never been described as a whole over a particular region – until now.

The monitoring of land subsidence is of vital importance for low-lying countries, but also areas which are prone to peculiar ground instability.
Spring is notoriously windy along the coast of California. Strong northwest winds can cause hazardous sea states to crop up out of nowhere, especially in the Santa Barbara Channel. But as dawn broke on a crisp April morning, the first rays of light revealed a glassy, calm channel. Not so much as a ripple disturbed the surface. These were perfect conditions for spotting one of the most elusive visitors to the channel's waters: basking sharks.
Remote sensing and satellite imagery have become common use in monitoring and modelling of various biological and physical characteristics of Earth - now Copernicus Sentinel-1 is giving a new approach for monitoring the evolution of shorelines.
The Copernicus Hackathons are a valuable asset of Europe's Earth Observation (EO) programme: Copernicus Hackathons foster the use of Copernicus free and open data amongst different developer communities. They are one of the four elements of the Copernicus Start-up Programme of the European Commission (EC), which is composed of:
Nestlé announced that 77% of its supply chain for agricultural commodities is verified deforestation-free. Thanks to Starling, our monitoring system for change in forest cover, Nestlé is changing the way they are managing deforestation risks.
Knee-deep in water on a picture-postcard Lesbos island beach, a team of Greek university students gently deposits a wall-sized PVC frame on the surface before divers moor it at sea.
A new web-based interactive tool for ocean mapping and planning created by NOAA and the Department of the Interior's Bureau of Ocean Energy Management, will give everyone from ocean industries to coastal managers, students, as well as the general public the opportunity to be an ocean explorer from their own computer.

It's that time again to reaquaint yourself with the health and well-being of our planet. We know what you're thinking … but it's not all bad news. NOAA scientists are using their expertise and innovation to help to solve Earth's biggest challenges.
Whether they're idyllic floating cotton balls on an otherwise blue sky or ominous grey swirls that block the sun, clouds all begin as an invisible dot of water vapor. This elusive gas has been tricky to measure and track – until now. Research scientists at NASA's Langley Research Center in Hampton, Virginia, have created a new airborne instrument that can directly measure water vapor and floating particles in the atmosphere. The new data will help check the accuracy of satellite measurements, and improve weather and climate forecasts.
The complete drying-up of Lake Aculeo in Chile was captured by the Copernicus Sentinel-2 satellite, enabling scientists to follow the water surface extent at high frequency, and thus witness this dramatic loss.

Scientists are working on a technique to track plastic debris in the ocean from space.
It's extremely challenging, especially since the individual pieces of litter are smaller than the minimum-sized objects that satellites can resolve.
The Antarctic Peninsula is the northernmost part of Earth's coldest continent, making it particularly vulnerable to a changing global climate. Surface melting of snow and ice initiated the breakup of the northernmost Larsen A ice shelf in 1995, followed in 2002 by the Larsen B ice shelf to the south, which lost a section roughly the size of Rhode Island.

An extensive review reveals that remote sensing is changing the way we manage water resources and suggests that the coming years will bring both exciting advancements and new challenges.
When we think of climate change, one of the first things to come to mind is melting polar ice. However, ice loss isn't just restricted to the polar regions. According to research published today, glaciers around the world have lost well over 9000 gigatonnes (nine trillion tonnes) of ice since 1961, raising sea level by 27 mm.
When a giant iceberg breaks away from near Britain's Halley research base, it won't be because of climate change.
