Who knew being a scientist could be as easy as pointing your phone at the sky? For the second year in a row, NASA and The GLOBE Program are asking citizen scientists to take out their phones and report what kinds of clouds they see.

Last week, students and environmentalists took part in a high-profile global climate strike started by youth activist Greta Thunberg. The remarkable media attention for the events has caused many to wonder about the science of climate change. How do we know what we know?
Copernicus services enable civil authorities to anticipate the spread of wildfires and to assess air pollution from forest blazes

Wildfires are a natural part of the Earth's ecology as they return nutrients from dead wood and dense undergrowth to the soil. They can, however, also lead to the loss of human and animal life, damage to property and the emission of atmospheric pollutants that can travel thousands of kilometres. Rising summer temperatures and the increased frequency of droughts due to climate change compound the risk by providing ideal conditions for fires to spread. Observations and forecasts are therefore vital to identifying potential hotspots and to managing the effects of these mostly human-induced events.

Featuring ECOPOTENTIAL, a European funded project that focuses on a set of internationally recognised protected areas, this video describes how the unprecedented availability of satellite data allow scientists to understand large scale changes in our environment and how best to protect it.

The extent of Arctic sea ice at the end of this summer was effectively tied with 2007 and 2016 for second lowest since modern record keeping began in the late 1970s. An analysis of satellite data by NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder shows that the 2019 minimum extent, which was likely reached on 18 September, measured 1.60 million square miles (4.15 million square kilometres).

Putting the world's eyes in the skies to work to improve human lives and combat climate change is now easier thanks to an overhaul of the Food and Agriculture Organization' innovative geospatial monitoring system.

Over 700 Earth observation satellites are orbiting our planet, transmitting hundreds of terabytes of data to downlink stations every day. Processing and extracting useful information is a huge data challenge, with volumes rising quasi-exponentially.

Researchers all over the world have a wealth of satellite data at their fingertips to understand global change, but turning a multitude of different data into actual information can pose a challenge. Using examples of Arctic greening and drought, scientists at ESA's ɸ-week showed how the Earth System Data Lab is making this task much easier.

Hot and dry. These are the watchwords for large fires. While every fire needs a spark to ignite and fuel to burn, it's the hot and dry conditions in the atmosphere that determine the likelihood of a fire starting, its intensity and the speed at which it spreads. Over the past several decades, as the world has increasingly warmed, so has its potential to burn.

Maxar Technologies will provide oceanographic data and saltwater fishing recommendations for SiriusXM's new Fish Mapping service announced 09 Sept. and available on Garmin International's GXM 54 satellite weather receiver.

On Monday morning, 09 September, Hurricane Dorian was a post-tropical storm after a mid-latitude weather front and cold seas had altered its tropical characteristics over the weekend. NASA compiled data on Hurricane Dorian and created a map that showed the heavy rainfall totals it left in its wake from the Bahamas to Canada.

Tracking spatio-temporal variations in flooded areas of wetlands is not an easy task, especially when they are characterised by a dense cover of emergent vegetation. Researchers in France developed a tool to monitor water in seasonal wetlands using Copernicus Sentinel-2 data, which exceed the performance of existing water indices.

While many NASA missions are tracking Hurricane Dorian as the storm makes its way toward the United States, some researchers are looking at what Dorian has already left behind.

Seeing things from a distance can help us gain new perspectives. For more than four decades, the National Aeronautics and Space Administration's (NASA) Landsat and, since 2014, the European Space Agency's (ESA) Sentinel satellites have captured images of Earth and helped humanity gain perspective on our planet and ourselves.
Through a series of case studies, EARSC (the European Association of Remote Sensing Companies) aims to gather quantitative evidence that the usage of Copernicus Sentinel data provides an effective and convenient support to various market applications. These studies are undertaken in the framework of the project "Showcasing the benefits brought by the usage of Sentinels data to society, environment and economy: a bottom-up assessment based on traceable impacts along selected value chains".
Ice fronts have retreated, rocky peaks are more exposed, fewer icebergs drift to the ocean: the branching network of glaciers that empty into Greenland's Sermilik Fjord has changed significantly in the last half century. Comparing Landsat images from 1972 and 2019, those changes and more come into view.

Daily U.S. air quality forecasts for particulate matter could potentially be more accurate as the result of incorporating NASA's Earth-observing satellite data, according to a recent study.

Thousands of fires have broken out in the Amazon rainforest. Satellite data show that there are almost four times as many fires this year compared to the same period last year. Apart from Brazil, parts of Peru, Bolivia, Paraguay and Argentina have also been affected.

NASA in cooperation with the U.S. Geological Survey is helping emergency planners in Southern California get a more complete picture of the increasing risk of coastal flooding by looking at the highest of tides —"king tides."

Thousands of fires are ravaging the Amazon rainforest in Brazil - the most intense blazes for almost a decade.
The northern states of Roraima, Acre, Rondônia and Amazonas have been particularly badly affected.
