Wetlands worldwide are vanishing at an alarming rate. New maps produced by ESA's GlobWetland Africa project show how satellite observations can be used for the effective use and management of wetlands in Africa.

Although plants don't sleep in the same way humans do, they have circadian rhythms — internal clocks that, like our own internal clocks, tell them when it's night and when it's day. And like many people, plants are less active at night. When the Sun comes up, they kick into gear, absorbing sunlight to convert carbon dioxide they draw from the air and water they draw from the soil into food, a process called photosynthesis. They also "sweat" excess water through pores on their leaves to cool themselves down, a process called evapotranspiration.
Climate experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) will release their annual assessment of global temperatures and discuss the major climate trends of 2019 during a media teleconference at 12:15 p.m. EST Wednesday, 15 January.

Days after a 6.4-magnitude earthquake rocked Puerto Rico, followed by hundreds of aftershocks, the full extent of damage is only beginning to be realised.

Ferocious bushfires have been sweeping across Australia since September, fuelled by record-breaking temperatures, drought and wind. The country has always experienced fires, but this season has been horrific. A staggering 10 million hectares of land have been burned, at least 24 people have been killed and it has been reported that almost half a billion animals have perished.

Satellite launching - especially those that are observing Earth - is not exactly news unless of course, the satellites are from private companies like SpaceX or Boeing so when NASA's observation satellite ICESat-2 was launched last September 2018, it was regarded as just another day at work. After all, there will be not much of a significant discovery on Earth since we know so much about it already, right? Wrong.
17 December 2019
For more than three decades, space agencies like NASA and ESA have been observing Earth from space and monitoring weather patterns and the global climate.

While two explorers were having problems cruising the ice across the North Pole on skies, due to bad weather and complications with equipment, the Copernicus Sentinel-1 satellites lent a hand to guide rescuers through the maze of ice and water to save the day.

"If you can't measure it, you can't manage it", said María Fernanda Espinosa Garcés, President of the United Nations General Assembly at the COP 24 in Katowice Poland, summing up how crucial satellites are for measuring climate change.

According to a new study, emergency responders could cut costs and save time by using near-real-time satellite data along with other decision-making tools after a flooding disaster.
22 November 2019
Italy has been victim of days-long flooding and high-tides, owing to the severe weather of the past weeks. Although forecasts do not promise an improvement just yet, the Copernicus Sentinels have teamed up to help monitor the situation.
18 November 2019
Planet Earth continued to sweat in unrelenting heat last month making October 2019 the second-hottest October recorded, just behind 2015.

Utah and New Jersey state public health officials are now using a NASA-enhanced website that began in California to strengthen mosquito control efforts. The invasive mosquito surveillance system, called CalSurv (short for California Vectorborne Disease Surveillance System), helps mosquito control agencies and public health officials monitor and respond to potential outbreaks of mosquito-borne diseases by mapping the insects that can carry these deadly viruses.

A new satellite-based map of a section of the Amazon Basin reveals that at least some of the massive fires burning there this past summer were concentrated in water-stressed areas of the rainforest. The stressed plants released measurably less water vapor into the air than unstressed plants; in other words, they were struggling to stay cool and conserve water, leaving them more vulnerable to the fires.
With traditional methods of data collection such as census and surveys being challenged by low response rates, experts are now asking if the use of earth observation — or EO — data to support monitoring of the Sustainable Development Goals can be a viable alternative.

NASA scientists are helping California create a detailed, statewide inventory of methane point sources - highly concentrated methane releases from single sources - using a specialized airborne sensor. The new data, published this week in the journal Nature, can be used to target actions to reduce emissions of this potent greenhouse gas.

On 11 October, some 95 km from the Saudi city of Jeddah, an Iranian-owned oil tanker was damaged, resulting in the loss of oil in the Red Sea. The Copernicus Sentinels are being used to monitor the resulting oil spill.
Millions more people will be at risk of coastal flooding from climate-driven sea-level rise later this century.

Wildfires have been making headlines again this month, with multiple fires burning in Lebanon and California, but these are just some of the many fires 2019 has seen. Fires in the Amazon sparked a global outcry this summer, but fires have also been blazing in the Arctic, France, Greece, Indonesia as well as many other areas in the world.
Mangroves are groups of trees and shrubs that live in coastal intertidal zones. Mangroves stabilize the coastline and provide a critical ecosystem for fish and other organisms, thus making them important lifelines for human and other species alike. But the mangroves in Sierra Leone are disappearing due to coastal erosion.
