From climate change to astronaut poo it was another interesting week in science and technology stories. Here are the ones I have selected to share with you:   Climate Change Study Goes Back 11,300 Years with Startling Conclusions; The Biggest Challenge for Human Flight to Mars an

By 2017 hydrogen-powered electric vehicles (EVs) will be on the road using fuel cell technology jointly developed by Ford, Nissan and Daimler. The three major automobile manufacturers are equal partners in a new joint venture to make the fuel cell EV a reality by that date. They join

In 2008 humanity reached a milestone. For the first time in our history more of us were living in cities than rural environments. Much of that growth has been happening in megacities in the Developing World. What’s a megacity? By definition it is a city with a population greater

My weekend newspaper on its “World” page had some interesting statistics about Sweden and waste-to-energy usage in that country. I learned that biomass generates more energy than oil in Sweden. And that by 2020 the country projects that 50% of all its total energy needs wi

In Africa, South America and Southeast Asia agricultural demand has lead to deforestation that is climate altering. We’ve known that deforestation and forest degradation contributes to increases in greenhouse gases through loss of biomass, decomposition and fires. But scientists

Scientists hypothesize, test, validate or disprove observation. Climate science is nascent but observations are concrete. Correlation cannot be overlooked. I don’t ascribe to a belief in a super being that sets the wheels of the universe in motion. I do believe that we humans ha

Does 2.75 degrees Celsius sound like a lot? For American readers that translates to 5 degrees Fahrenheit. Now when you say it in Fahrenheit it starts to sound like a lot more. And it represents continuing evidence of rapid climate change in the high Arctic, a phenomenon being seen not

Agriculture Update: Robots on the Farm Blue River Technology, a Stanford University start up, has developed a robotic system that can differentiate a weed from surrounding crops. The device gets pulled by a tractor and includes a camera and computer working together to categorize plan

Considered by many scientists to be the highest safe level for the concentration of the gas in the atmosphere – 350 parts per million (PPM) , CO2 levels are well in excess of that number today. Standing globally at 395 PPM, the most recent Arctic readings this spring measure mor

Today is Earth Day and it seems appropriate to include an article about climate change. Last week a study was published in Nature Geoscience showing that some areas of the Himalayas were gaining ice steadily. The study compared data collected on the Space Shuttle Endeavour in 2000 wit
