Climate change has inflicted more damage on the U.S. military than Iranian missiles

  Climate change has inflicted more damage on the U.S. military than Iranian missiles Among the Pentagon's fears is that weather-related catastrophes could mean it has to commit most of its resources to disaster relief missions.For several days, it seemed like the Air Force had lost about 10 percent of its deadliest fighter aircraft in one fell swoop, though by good fortune, the Raptors all reportedly proved repairable. The Air Force is still footing a staggering $5 billion bill to rebuild Tyndall and another base and move F-22 operations elsewhere.

The Satellite Application Facility on Climate Monitoring (CM SAF) provides datasets to some 3,500 users worldwide. This data can be used to help Besides national weather services and international research institutes, users include commercial businesses, as well as insurance companies and

Climate satellites are operated by agencies around the world, from Kazakhstan to Chile. But not every country has the resources to support their own satellite . The graph below shows that large nations such as China, India and the US top the list of countries with the most climate satellites in operation, along

A Russian rocket has carried four small satellites from a German science project into space. They should help to create three-dimensional images of the earth and cloud formations.

satellites are not only misshapen objects that float around in space and only affect us when they provide data for the weather report or the navigation system in the car. Various projects have been in existence for a long time, for example, to ensure comprehensive internet coverage even in remote areas. Elon Musk's Starlink is a well-known example here. But German companies are also working on modern satellite systems. One such was launched yesterday, Monday, from the Russian spaceport Plesetsk.

Republicans Claim Addressing Climate Change Is Too Expensive. Americans Aren’t Buying It, a New Poll Shows

  Republicans Claim Addressing Climate Change Is Too Expensive. Americans Aren’t Buying It, a New Poll Shows Nearly half of Americans think addressing climate change will help the economy, according to a new pollBut few Americans are buying it, a new poll shows. Nearly half of Americans think addressing climate change will help the economy while only 29% believe that climate policy will cause harm, according to a new report by researchers at Stanford University, Resources for the Future (RFF) and ReconMR. “It’s just an argument that doesn’t work,” says report author Jon Krosnick, a Stanford social psychologist professor who studies political behavior of the argument that climate policy hurts jobs. “The argument has never convinced even a majority of Republicans.

The relationship between a modern small satellite and a ldquoconventionalrdquo large satellite is similar to that between a modern compact laptop and a ldquoconventionalrdquo work-station computer. This paper gives an overview of antenna technologies for applications in modern small satellites .

The researchers used new satellite -based land cover and land use maps, along with other climate and soil data and advanced techniques to arrive at NASA scientists conduct research to map the functional traits of ecosystems. Models, combined with satellite observations, can examine whether

Netsat starts with 4 pico satellites

The project of the Würzburg Center for Telematics comprises four pico satellites, so-called Netsats. They each weigh around four kilograms and are 10 by 10 by 30 centimeters in size. In a group of four, they should independently coordinate their positions in three-dimensional space at a height of around 600 kilometers. Above all, they should measure and analyze clouds, but also the earth.

The specialty of the Netsat is above all their independence. Although there is a radio link to the Bavarian town of Würzburg, it only coordinates the satellites within a rough framework. The Netsats exchange their positions via radio and coordinate relatively autonomously and without the influence of the ground station. A special electric drive allows them to approach each other up to 20 meters.

Climate change poses a growing threat to hundreds of hazardous waste Superfund sites

  Climate change poses a growing threat to hundreds of hazardous waste Superfund sites Hurricanes, floods and wildfires imperil hundreds of toxic sites. But the Trump administration won't talk about the rising risks.BARRETT, Texas — Fred Barrett thought he’d wait out Hurricane Harvey at his home in this town outside Houston, founded by his great-grandfather in 1889. He prepared for heavy rain, wind and flooding.

The swarm technology of the Netsats is intended to lay the foundation for new possibilities in climate research. Clouds in particular play an important role. With the help of the many small pico satellites, it should be possible to measure clouds from different positions, as with a computer tomograph. The three-dimensional images should then provide further knowledge and, for example, enable more realistic cloud simulations. The EU-funded CloudCT project is also located at the Würzburg Center for Telematics.

criticism of Starlink and Co

However, it is mainly experts who criticize the commercial projects of Starlink, Amazon and other companies. Tens or even hundreds of thousands of small and tiny satellites are said to orbit the earth by now - nobody seems to know for sure. Not only do they make work difficult for astronomers, who are increasingly finding traces of light on their recordings.

Space debris and collisions are also becoming more and more of a problem. For example, Starlink claims to have disused satellites crash and burn up in a controlled manner, but the company claims that it has already lost at least three satellites - and can no longer establish contact with them. Experts expect this problem to grow. A study by the Technical University of Braunschweig claims that in the year 2100 there should be so much space junk in orbit that space travel becomes impossible. That could also affect Elon Musk's plans for a Mars colonization .
