Modeling the past to understand the future of a stronger El Nino
El Nino is not a contemporary phenomenon; it's long been the Earth's dominant source of year-to-year climate fluctuation. But as the climate warms and the feedbacks that drive the cycle change, researchers want to know how El Nino will respond. A team of researchers led by the University of Wisconsin's Zhengyu Liu published the latest findings in this quest Nov. 27, 2014 in Nature.

Stanford engineers invent high-tech mirror to beam heat away from buildings into space
Stanford engineers have invented a material designed to help cool buildings. The material reflects incoming sunlight, and it sends heat from inside the structure directly into space as infrared radiation.

Satellite views early Thanksgiving travel trouble areas in US
As the US Thanksgiving holiday approaches this Thursday, Nov. 27, NOAA's GOES-East and GOES-West satellites are keeping a weather eye out for storms that may affect early travelers. In an image from Nov. 25, the satellites show an active weather pattern is in place for travelers across the central and eastern US.

Climate change could affect future of Lake Michigan basin
Climate change could lengthen the growing season, make soil drier and decrease winter snowpack in the Lake Michigan Basin by the turn of the century, among other hydrological effects.

Global warming cynics unmoved by extreme weather
What will it take to convince skeptics of global warming that the phenomenon is real? Surely, many scientists believe, enough droughts, floods and heat waves will begin to change minds. But a new study led by a Michigan State University scholar throws cold water on that theory.

New volume documents the science at the legendary snowmastodon fossil site in Colorado
Four years ago, a bulldozer turned over some bones at Ziegler Reservoir near Snowmass Village, Colorado. Scientists from the Denver Museum of Nature & Science were called to the scene and confirmed the bones were those of a Columbian mammoth, setting off a frenzy of excavation, scientific analysis, and international media attention. This dramatic and unexpected discovery culminates this month with the publication of the Snowmastodon Project Science Volume in the international journal Quaternary Research.

Climate change will slow China's progress in reducing infectioius diseases
A new study found that by 2030, changes to the global climate could delay China's progress reducing diarrheal and vector-borne diseases by up to seven years.

Crops play a major role in the annual CO2 cycle increase
In a study published Wednesday, Nov. 19, in Nature, scientists at Boston University, the University of New Hampshire, the University of Michigan, the University of Minnesota, the University of Wisconsin-Madison and McGill University show that a steep rise in the productivity of crops grown for food accounts for as much as 25 percent of the increase in this carbon dioxide seasonality.

Sun's rotating 'magnet' pulls lightning towards UK
The sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper atmosphere.

High earthquake danger in Tianjin, China
With a population of 11 million and located about 100 km from Beijing (22 million people) and Tangshan (7 million people), Tianjin lies on top of the Tangshan-Hejian-Cixian fault that has been the site of 15 devastating earthquakes in the past 1,000 years. An example of the disastrous events is the 1976 magnitude 7.6 Tangshan Earthquake, which killed a quarter million people.

Adjusting Earth's thermostat, with caution
A team of researchers from the Harvard School of Engineering and Applied Sciences has outlined how a small-scale 'stratospheric perturbation experiment' could work. By proposing, in detail, a way to take the science of geoengineering to the skies, they hope to stimulate serious discussion of the practice by policymakers and scientists.

Climate change was not to blame for the collapse of the Bronze Age
Scientists will have to find alternative explanations for a huge population collapse in Europe at the end of the Bronze Age as researchers prove definitively that climate change -- commonly assumed to be responsible -- could not have been the culprit.

New findings could help keep satellites and space debris from colliding
Half a million objects, including debris, satellites, and the International Space Station, orbit the planet in the thermosphere, the largest layer of Earth's atmosphere. To predict the orbits -- and potential collisions -- of all this stuff, scientists must forecast the weather in the thermosphere.

Mars, too, has macroweather
Weather, which changes day-to-day due to constant fluctuations in the atmosphere, and climate, which varies over decades, are familiar. More recently, a third regime, called 'macroweather,' has been used to describe the relatively stable regime between weather and climate. A new study by researchers at McGill University and UCL finds that this same three-part pattern applies to atmospheric conditions on Mars.

Lightning expected to increase by 50 percent with global warming
UC Berkeley atmospheric scientist David Romps and his colleagues looked at predictions of precipitation and cloud buoyancy in 11 different climate models and concluded that their combined effect will generate 50 percent more electrical discharges to the ground by the end of the century because of global warming. The main cause is water vapor, which fuels explosive deep convection in the atmosphere. The more convection, the greater the charge separation and the more cloud-to-ground strikes.

Researchers calculate 'hidden' emissions in traded meat

Global warming stops at nothing -- not even the groundwater, as a new study by researchers from ETH Zurich and KIT reveals: the groundwater's temperature profiles echo those of the atmosphere, albeit damped and delayed.

New global maps detail human-caused ocean acidification
A team of scientists has published the most comprehensive picture yet of how acidity levels vary across the world's oceans, providing a benchmark for years to come as enormous amounts of human-caused carbon emissions continue to wind up at sea. The maps are published in the journal Marine Chemistry.

Global warming not just a blanket -- in the long run, it's more like tanning oil
Instead of carbon dioxide being like a blanket that slowly warms the planet, after about a decade most warming comes from melting ice and snow and a more moist atmosphere, which both cause the Earth to absorb more shortwave radiation from the sun.

How variable are ocean temperatures?
The earth's climate appears to have been more variable over the past 7,000 years than often thought. In a new study, scientists from the Potsdam-based Alfred Wegener Institute and Harvard University show that sea surface temperatures reconstructed from climate archives vary to a much greater extent on long time scales than simulated by climate models. The consequence: either the analysed climate archives supply inaccurate temperature signals, or the tested models underestimate the regional climate fluctuations in the Earth's recent history.
