... the pyramid can accommodate whole cities in complexes that take up less than 10% of the original land surface. “Transport throughout the complex would be connected by an integrated 360 degree network (horizontally and vertically) so cars would be redundant. Biometrics would provide security with facial recognition technology. Timelinks has already patented the design and technology...

Imagine a new kind of farming. Not for food, or for fuel crops (corn, switch grass etc) but a kind of farming that traps atmospheric carbon dioxide and rebuilds lost soils. That’s carbon farming. The U.S. Geological Survey (USGS), the California Department of Water Resources (DWR) and the University of California, Davis plan to make it happen. Carbon farming could restor wetlands and fight global...

... online last April in Global Change Biology. The effect could be huge: About 35% of Earth’s land surface, or 5.2 billion hectares, is desert and semiarid ecosystems. If the Mojave readings represent an average CO2 uptake, then deserts and semiarid regions may be absorbing up to 5.2 billion tons of carbon a year–roughly half the amount emitted globally by burning fossil fuels, says...

This optimisation includes the use of a ‘gated dump drain’ allowing the readout of selected image lines and the dumping of unwanted data. It also includes the use of graded thickness anti-reflection coating, giving the minimum possible reflection from the silicon surface for all wavelengths of interest. Sentinel-3 will be used to study sea surface topography, sea and land surface...

Image from StormyDog It may seem hard to believe, but the planet's wetlands, which comprise 6% of its land surface area, contain 771 billion tons of carbon dioxide -- 20% of the Earth's carbon supply and roughly the same amount that is currently in the atmosphere. Wetlands include a wide array of different ecosystems, such as marshes, swamps, river deltas and mangroves,...
