A vast glacier-fed river which flowed from Canada's Yukon territory across Alaska to drain into the Bering Sea has disappeared in just four days, in what scientists believe is the first observed case of "river piracy".

High average temperatures in the first three months of 2016 [WINTER months!] caused a dramatic spike in the amount of meltwater flowing from the Kaskawulsh glacier, carving a deep canyon in the ice and redirecting the flow toward the Alsek River in the south, rather than the north-flowing Slims River.

That changed the Slims River from a three-metre-deep, raging torrent to a place where "massive afternoon dust storms occurred almost daily", according to a scientific paper published in the journal Nature Geoscience.

Lee tries to derail all AGW discussion. He drags in stupid, unreliable links from denier, not science, websites. He is best just ignored.

I finished my post by talking about how the Libs had sabotaged action on AGW. This belongs in PolSux.

Gas emits a lot less CO2 per unit of electricity generated.

So the South of the continent is drying out, as well as warming, while the north is getting wetter. So what do we do, move Perth into the Kimberleys, Adelaide into Darwin and Melbourne and Sydney into Brisbane? Or could we do a Snowy Mountains type scheme on northern rivers? Redirect water south and west, creating plenty of hydro (including pumped hydro if need be) and sending water into the headwaters of the Darling River.

And it is all to do with that pesky CO2. The magic gas that can move rainfall.

And then of course we have CO2 as refrigerant. Go figure.

NASA has released data showing how temperature and rainfall patterns worldwide may change through the year 2100 because of growing concentrations of greenhouse gases in Earth’s atmosphere.

The dataset, which is available to the public, shows projected changes worldwide on a regional level in response to different scenarios of increasing carbon dioxide simulated by 21 climate models. The high-resolution data, which can be viewed on a daily timescale at the scale of individual cities and towns, will help scientists and planners conduct climate risk assessments to better understand local and global effects of hazards, such as severe drought, floods, heat waves and losses in agriculture productivity.

“NASA is in the business of taking what we’ve learned about our planet from space and creating new products that help us all safeguard our future,” said Ellen Stofan, NASA chief scientist. “With this new global dataset, people around the world have a valuable new tool to use in planning how to cope with a warming planet.”

The new dataset is the latest product from the NASA Earth Exchange (NEX), a big-data research platform within the NASA Advanced Supercomputing Center at the agency's Ames Research Center in Moffett Field, California. In 2013, NEX released similar climate projection data for the continental United States that is being used to quantify climate risks to the nation’s agriculture, forests, rivers and cities.

"This is a fundamental dataset for climate research and assessment with a wide range of applications,” said Ramakrishna Nemani, NEX project scientist at Ames. “NASA continues to produce valuable community-based data products on the NEX platform to promote scientific collaboration, knowledge sharing, and research and development."

This NASA dataset integrates actual measurements from around the world with data from climate simulations created by the international Fifth Coupled Model Intercomparison Project. These climate simulations used the best physical models of the climate system available to provide forecasts of what the global climate might look like under two different greenhouse gas emissions scenarios: a “business as usual” scenario based on current trends and an “extreme case” with a significant increase in emissions.

The NASA climate projections provide a detailed view of future temperature and precipitation patterns around the world at a 15.5 mile (25 kilometer) resolution, covering the time period from 1950 to 2100. The 11-terabyte dataset provides daily estimates of maximum and minimum temperatures and precipitation over the entire globe.

NEX is a collaboration and analytical platform that combines state-of-the-art supercomputing, Earth system modeling, workflow management and NASA remote-sensing data. Through NEX, users can explore and analyze large Earth science data sets, run and share modeling algorithms and workflows, collaborate on new or existing projects and exchange workflows and results within and among other science communities.

NEX data and analysis tools are available to the public through the OpenNEX project on Amazon Web Services. OpenNEX is a partnership between NASA and Amazon, Inc., to enhance public access to climate data, and support planning to increase climate resilience in the U.S. and internationally. OpenNEX is an extension of the NASA Earth Exchange in a public cloud-computing environment.

NASA uses the vantage point of space to increase our understanding of our home planet, improve lives, and safeguard our future. NASA develops new ways to observe and study Earth's interconnected natural systems with long-term data records. The agency freely shares this unique knowledge and works with institutions around the world to gain new insights into how our planet is changing.

You do know the difference between projections and data; don't you?

When there are so many unknowns in climate science, it is merely projections. It could only come true if ALL the underlying assumptions come true.

Note the difference in the certainties.

I have shown the Ice Age is not happening

The SMH editorialises that there are worrying signs at the fringes of politics that an irrational and unscientific approach to policy is making inroads. We should put science at the centre of society it says. Will the SMH be branded an heretic organisation because of this?
