Study finds early warning signals of global ocean conveyor belt collapse

We could see early warning signs of the collapse of a key component of the global climate up to 250 years in advance, a new study has shown – ample time to either prevent or prepare for the consequences of abrupt climate change. The University of Exeter study analyzed the Atlantic Meridional Overturning Circulation (AMOC), sometimes referred to as the global ocean conveyor belt, in a highly-complex and realistic simulation model, and identified the likely mechanisms that would drive such a collapse.Read More

Study shows CO2 causes global warming faster than feared

Any given CO2 emission will have its maximum warming effect just 10 years later, new research from the Carnegie Institution for Science shows. The Institute of Physics (IOP) says this research, published in full on the web today, has "dispelled a common misconception" that the warming effects of CO2 emissions aren't felt for decades.

Latest supercomputers run truer simulations of extreme weather

High-resolution simulations of the global climate can now perform much closer to actual observations, and they perform far better at reproducing extreme weather events, a new Berkeley Lab study has found. Lead author Michael Wehner heralds this news as evidence of a golden age in climate modeling, as not only did the simulation closer match reality but it also took a fraction as long to complete as it would have in recent history – just three months compared to several years.Read More

How big data is helping farmers save millions

Data scientists studying crop growth and weather patterns in Colombia have advised rice farmers not to plant crops, saving millions of dollars. The International Center for Tropical Agriculture (CIAT) and the Colombian Rice Growers Federation have developed a computer model that can work out what crops work best under specific weather conditions in certain areas.

MIT's new cement recipe could cut carbon emissions by more than half

As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. Calcium-based substances are heated at high temperatures to form the cement, a process that produces carbon dioxide. But by slightly altering the quantities of materials used, scientists from MIT have uncovered a new method of cement mixing that could reduce these emissions by more than half.Read More

Italian explorer plans to live on an iceberg for up to a year

Italian explorer Alex Bellini has conceived an extraordinary plan to live alone on a drifting iceberg in northwest Greenland for up to a year, or until it melts away – whichever happens first. He aims to stay alive during this time in a tiny survival pod, and hopes his experience will encourage further discourse on climate change and the environment in general. Read More

Sun’s activity shown to influence natural climate change

In a new study that may greatly add to our understanding of the drivers behind climate change, researchers from Lund University in Sweden claim to have accurately reconstructed solar activity levels during the last ice age. By analyzing trace elements in ice core samples in Greenland and cave mineral formations in China, the scientists assert that regional climate is more influenced by the sun than previously thought.Read More

Using GPS to measure changes in sea level

Measuring sea level is not only an invaluable tool for pilotage, navigation, aeronautics, cartography, sea charting, and geology, it’s also a fundamentally important metric for measuring possible evidence of climate change, and for measuring the direction, extent and rate of such change. Johan Löfgren and Rüdiger Haas of Chalmers University in Sweden have developed a new way of measuring sea level that uses satnav signals for constant, real-time monitoring that promises new insights into many fields, including climate change.
