Europe Sets Heat Record – The temperature in Floridia, Sicily hit 124 degrees, the highest ever recorded in Europe. That means the highest temperatures ever recorded in Europe and North America happened barely a month apart. Unfortunately, I doubt either record will last very long.
Study says “blue hydrogen” may be worse than Natural Gas – Many people believe hydrogen will be an essential zero-carbon fuel. There are a few ways of producing hydrogen, the most common is called “gray” hydrogen and it involves using natural gas. Blue hydrogen was supposed to be better for the environment, but a new study concludes it might be worse than just using natural gas directly. That leaves only “green” hydrogen as a viable path. Green hydrogen involves using renewable energy to power electrolysis machines that separate water into hydrogen and oxygen. In order for this to make financial sense, the cost of renewable energy and electrolysis must come down significantly.
Attribution Science Powers IPCC Report – Between the last IPCC report in 2014 and today, something called attribution science has gotten much more sophisticated. This new knowledge allows us to attribute individual weather events to climate change. For many years, we simply could not attribute weather events with a changing climate, making it very hard to convince people. Some bad faith commentators would often point out (correctly) that we could not blame climate change or a certain hurricane or fire, and then they’d argue that we shouldn’t worry about climate because of this. That was a stupid argument then, but it makes less sense now. Since we can actually make that attribution. This is one of several new scientific tools developed over the past year that have removed any lingering doubts about our role in a changing climate.
