This incongruity provides evidence of human influences on climatechange, says Kaufman. Gifford Miller of the University of Colorado, Boulder, a member of the study team. The new study is the first to quantify at a decadal resolution a pervasive cooling across the Arctic from the early part of the first millennium C.E.
Ceres recently released a new report concluding that coal-to-liquid (CTL) and oil shale technologies face significant environmental and financial obstacles—from water constraints, to technological uncertainties to regulatory and market risks—that pose substantial financial risks for investors involved in such projects.
The largest global oil shale deposits—estimated to be equivalent to 1,500 Gbbl oil equivalent—are found in the Green River formation of Colorado, Utah, and Wyoming. The ATP retort has lower water requirements than previous surface retort designs, and can also utilize fine particles, thus reducing shale waste. Credit: ACS.
Dlugokencky and his colleagues from the United States and Brazil note that while climatechange can trigger a process which converts trapped carbon in permafrost to methane, as well as release methane embedded in Arctic hydrates—a compound formed with water—their observations “ are not consistent with sustained changes there yet.”.
On the road from NorCal to Colorado, there is a lot of nature one can experience, from national parks, to lakes, to breathtaking mountain towns. Features such as a hot-water shower and interior climate controls provide comfort. A way to diverge from the charging path.
The Creative Greenius says you can now expect a bold United States policy on cutting greenhouse gas emissions, a rapid shift away from carbon-based fuels to renewables and a science-based approach to water policy and other critical resources. Change is but mere weeks away. There’s no good news anywhere on the water horizon.
PRIME Coalition, a 501(c)(3) public charity funding tech start-ups that fight climatechange, closed three new investments: Opus 12 in Berkeley, CA; Mallinda in Denver, CO; and Lilac Solutions in Oakland, CA. In addition, the prepreg is pre-cured, shelf-stable, and requires no refrigeration for transport and storage.
Most climate models have suggested that evapotranspiration, which is the movement of water from the land to the atmosphere, would increase with global warming because of increased evaporation of water from the ocean and more precipitation overall. Data indeed show that some areas are wetter than they used to be. Jung et al.
The metabolism of a city can be interpreted either primarily in terms of energy flows or more broadly including a city’s flows of water, materials, and nutrients. Timothy Hillman, University of Colorado. Anu Ramaswami, University of Colorado. Tags: ClimateChange Emissions Lifecycle analysis. Charles Kolb.
First, an electric potential will be applied to water to simultaneously produce acidity and alkalinity. Colorado School of Mines. The technologies use electricity to extract valuable metal ions from the surrounding mineral matrix at sub-boiling temperatures. Feedstocks will include Li/Ni/Ca/Mg-rich igneous and sedimentary minerals.
Climatechange mitigation will create new natural resource and supply chain opportunities and dilemmas, because substantial amounts of raw materials will be required to build new low-carbon energy devices and infrastructure. Their paper is published in Science.
Scientists from the Karlsruhe Institute of Technology (Germany), University of Colorado Boulder, and Universidad Nacional Autónoma de México performed a “CT Scan” of the atmosphere, moving along latitudes and longitudes, measuring particle concentrations and compositions in the upper troposphere.
And in the aftermath of a natural disaster like a tornado or wildfire, the vehicle, called H2Rescue , can supply electric power and potable water to survivors while acting as a temperature-controlled command center for rescue personnel. Any time the fuel cell is producing energy to move the vehicle or to export power, it’s generating water.”
However, the technologies that have released the new supplies—hydraulic fracturing and horizontal drilling—have also unleashed anxieties about contaminated drinking water, induced earthquakes and lenient regulation. Earlier post.).
