From Carbon To Metals: the Renewable Energy Transition

Image
The world is transitioning from a carbon-intensive to a metals-intensive economy. Low-carbon technologies use much larger amounts of metal than traditional fossil fuel-based systems. Demand for metals is thus rising exponentially, fuelling a boom in mining and production. But this creates an environmental challenge. Metals extraction and processing is a significant contributor to global warming and a major pollutant. Unless more environmentally-friendly ways of generating energy from renewable sources can be found, saving the planet from carbon emissions may prove extremely costly for our fellow creatures and even for ourselves.   Climate change is driving a metals and mining boom The Paris Climate Agreement , which was ratified by 174 countries and the European Union in 2016, aims to keep global warming “well below” 2 degrees Celsius this century and ideally not more than 1.5 degrees Celsius. Achieving this challenging target is dependent to an unknown degree on factors outside gove

Coronavirus's priceless gift

The  freesias that my daughter sent me  are long dead, but the clematis in my garden is in full flower, and the flowers smell of vanilla. It has taken over six weeks for my sense of smell to return. But I was only mildly ill. For many people, the road to recovery is much longer. Initially, coronavirus was thought to be a respiratory illness causing cough, fever and breathing difficulties. But the range of symptoms that the virus produces is now known to be much wider. Headache, muscle pains, fatigue, nausea, diarrhoea are all now recognised as symptoms of coronavirus infection. There is growing evidence that it disturbs the blood clotting mechanism and can trigger heart attacks or strokes. It also seems to have caused renal or liver failure in some patients. And there are worrying reports of long-term problems such as a weakened heart or immune system. It's also difficult to diagnose. Some very sick people don't have a cough or fever, or obvious breathing difficulties. So

The Broken Contract

So the Lord God said to the serpent,  “Because you have done this, cursed are you above all livestock and all wild animals! You will crawl on your belly and you will eat dust all the days of your life. And I will put enmity between you and the woman, and between your offspring and hers; he will crush your head, and you will strike his heel.” To the woman he said, “I will make your pains in childbearing very severe; with painful labor you will give birth to children. Your desire will be for your husband, and he will rule over you.” To Adam he said, “Because you listened to your wife and ate fruit from the tree about which I commanded you, ‘You must not eat from it,’ cursed is the ground because of you; through painful toil you will eat food from it all the days of your life. It will produce thorns and thistles for you, and you will eat the plants of the field. By the sweat of your brow you will eat your food until you return to the gro
