Hot rain? Not quite, but one of the unique characteristics of the soaker aimed at the Bay Area on Friday and Saturday is its warmth.

Forecasters are calling this “atmospheric river” with a moisture plume stretching back to the Hawaiian Islands “remarkable,” and saying it’s likely to be the warmest storm of the season.

“The reason for this warmth is the subtropical origins of the air in this system,” says Daniel Swain, a climate scientist at UCLA. “It won’t be unusually warm for April, per se, when most days are rain-free, but it will certainly be warm for a rainy day at any time of the year.

Postponing Day Zero in Cape Town for 2018 comes as no surprise. There was no sense to it once the day had been pushed into the winter rainfall period. It also didn’t make sense for the Western Cape and Cape Town governments to continue drafting detailed logistical plans for points of water distribution in the event that taps were turned off across the city.

But Cape Town’s water supplies remain at high risk because the long-term predictions for rainfall in the south-western Cape remain uncertain. Dam levels continue to fall while people are struggling to achieve the city’s target of 450 million litres per day. And yields from new water schemes will only be known in the coming months and next year.

The general perception is that the onset of climate change would be slow and measured. This would afford authorities the time to intervene with considered plans. But climate change is a disrupter and takes no prisoners. Over the past three years, Cape Town and the surrounding regions has experienced successive years of well below average rainfall. The experience is changing the way people think about water and how it is managed.

If we are to have truly smart cities our transport systems will have to be more cost-effective, safer and sustainable. Perhaps most of all they will need to be more integrated, as the EU-funded project MFDS demonstrates.

The stated aim of the EU’s ‘smart, green and integrated transport’ initiative is to build a European transport system that is ‘resilient, resource-efficient, climate- and environmentally friendly, safe and seamless for the benefit of all citizens, the economy and society.’

In contribution, the EU-funded MFDS project has developed a versatile and affordable ‘Intelligent Transport System’ offering several functions including wrong-way driver detection, traffic congestion detection, vehicle counting by vehicle classification and parking accounting. The core innovation of MFDS is the system’s ability to perform its functions simultaneously, while remaining low-cost to buy and install, as well as running on minimum power. The project’s feasibility study has demonstrated that the system will be of interest to multiple EU markets.

According to the United Nations, 30,000 people die each week from the consumption and use of unsanitary water. Although the vast majority of these fatalities occur in developing nations, the U.S. is no stranger to unanticipated water shortages, especially after hurricanes, tropical storms and other natural disasters that can disrupt supplies without warning.

Led by Guihua Yu, associate professor of materials science and mechanical engineering at The University of Texas at Austin, a research team in UT Austin’s Cockrell School of Engineering has developed a cost-effective and compact technology using combined gel-polymer hybrid materials. Possessing both hydrophilic (attraction to water) qualities and semiconducting (solar-adsorbing) properties, these “hydrogels” (networks of polymer chains known for their high water absorbency) enable the production of clean, safe drinking water from any source, whether it’s from the oceans or contaminated supplies.

The findings were published in the most recent issue of the journal Nature Nanotechnology.

Humanity’s brutal and bellicose past provides ample justification for pursuing settlements on the moon and Mars, Elon Musk says.

The billionaire entrepreneur has long stressed that he founded SpaceX in 2002 primarily to help make humanity a multiplanet species — a giant leap that would render us much less vulnerable to extinction.

Human civilization faces many grave threats over the long haul, from asteroid strikes and climate change to artificial intelligence run amok, Musk has said over the years. And he recently highlighted our well-documented inability to get along with each other as another frightening factor. [The BFR: SpaceX’s Mars Colony Plan in Images].

China’s defunct space station Tiangong-1 will soon plummet toward Earth, likely this weekend. You will almost certainly not be harmed in any way by it—the odds of it striking an individual person are worse than winning the lottery or being struck by lightning. You should not worry about it.

But we’re humans. We’re all probably wondering, what happens if it becomes clear that pieces of the debris will strike a populated area? This is a long discussion that far predates Tiangong-1.

China launched the house-sized Tiangong-1 space station in 2011. It was a prototype that could only hold a three-person crew, and the plan was for it to fall back to Earth in a controlled reentry, meaning scientists would get to pick where it lands. In 2016, China informed the UN that the satellite was no longer functioning, but denied that it lost control of the ship in some more recent reports. Tiangong-1’s orbit is decaying as the craft slowly succumbs to Earth’s gravity.

Long regarded as a laggard in the fight against climate change, India is building massive solar stations at a furious clip, helping to drive a global revolution in renewable energy and reduce its dependence on coal and other carbon-spewing fossil fuels blamed for warming the planet.

Scientists have discovered 15 new planets, including a “super-Earth” that may have liquid water on its surface.

The planets are orbiting small, cool stars near our solar system that are known as “Red Dwarfs.”

One of the brightest Red Dwarfs, K2-155, has three “super-Earths,” one of which, K2-155d, could be within the star’s habitable zone. K2-155d, which has a radius 1.6 times that of Earth, may harbor liquid water, according to three-dimensional global climate simulations.

Elon Musk, the head of SpaceX and Tesla, came to SXSW this week and gave a grave talk about the future of humanity, warning about the dangers of nuclear war, climate, change, and runaway AI and telling the audience that the only way to keep humanity alive is to colonize the Solar System.
