The latest attempt to increase awareness around climate change is the Climate Strike protests that popped up around the world 🌍 last week.
Most reasonable people agree 👍 climate change is happening and that the ever increasing amounts of carbon dioxide in the air is problematic – you personally may be only dumping a few tons a year into the air but there are millions who live in cities that are dumping trillions of tons into the atmosphere. 🌆
What to do about it? On paper 📄 the trendy green technologies of the day are often brought out – solar panels, wind turbines, LED light bulbs 💡 and of course electric cars 🚙 . But when you look at the math – land use, cost and technology limitations – the math is hard to make work. Most of the technologies proposed are just swaps of fossil and more energy intensive technologies for slightly less energy intensive ways of doing things. ⚡
You have those who advocate behavioral changes – eat less meat 🍖 and dairy 🐮, recycle ♻ more, use public transport 🚍. Maybe buy more products made from hemp 🌿, buy trendy green things and skip the straws and the plastic water 💦 bottles. Those things certainly feel good if you are interested in the saving the earth 🌎. But they aren’t systematic changes.
You have governments like New York State promising they’ll work for ambitious climate goals. 🗽 They make long lists of promises and laws 📑 but their promises don’t always add up to their actions as they dig deeper into the next generation of fossil technologies ⛽ ignoring the consequences of their own actions.
What’s the solution? I don’t know for sure but I think sin taxes on fossil fuels can help. 💰 Oil, coal and natural gas are underpriced, they are too cheap to burn, distorting the value of the energy ⚡ services they provide. I like most people don’t want to pay more for electricity or gas for my big jacked up truck 🚚 but I know if it hurt in my pocket more I’d be a lot more responsible with my use of energy.
But of course, the politicians don’t want to implement unpopular policies, because they want to be reelected and loved by their constituents. And if they get voted ❎ out of office, their replacement will just roll back 🔙 their unpopular policies.
When planning for the future, certainty can be hard to come by. That’s certainly the case when it comes to climate change. Yet scientists still urge confidence in their models. Why?
Modern life is made up of predictions and models of what we think that future looks like. We expect the economy to grow at 2 or 3 percent a year in real dollars over time and inflation to exist at a similar rate. Models aren't perfect but what is the alternative? If we have no trust in the models we can't plan for the future.
melda, Dorian, Florence, Harvey, and Idai are examples of storms we have been seeing more often in recent decades: ones that move more slowly over land, resulting in increased flooding and damage. The forward speed of tropical cyclones (which includes all hurricanes, tropical storms, and tropical depressions) has decreased globally by about 10% since 1949, according to a 2018 paper in the journal Nature by NOAA hurricane scientist Dr. Jim Kossin. As a result of their slower forward motion, these storms are now more likely to drop heavier rains, increasing their flood risk. Most significantly, the study reported a 20% slow-down in storm translation speed over land for Atlantic storms, a 30% slow-down over land for Northwest Pacific storms, and a 19% slow-down over land for storms affecting the Australia region.
“Oh, come on, give me a break,” Warren said in response to the lightbulb question, in one of the breakout moments of the night. “This is exactly what the fossil fuel industry wants us to talk about. ... They want to be able to stir up a lot of controversy around your lightbulbs, around your straws, and around your cheeseburgers, when 70 percent of the pollution, of the carbon that we’re throwing into the air, comes from three industries.”
The disease, which has made kidney failure the second-leading cause of death in Nicaragua and El Salvador, was first reported in the 1990s. It was a strange new type of kidney failure. Sugar cane cutters from plantations in Nicaragua, El Salvador and Guatemala were turning up at clinics with end-stage kidney disease. Some had been in what seemed to be perfect health just a few years before. These laborers didn't have diabetes or hypertension or other factors that might explain why their kidneys were failing.
A bleak new federal report found that carbon dioxide in the atmosphere rose to levels the world has not seen in at least 800,000 years, highlighting the irreversible and mounting deleterious effects of human activity on the planet, as ABC News reported.
Global carbon dioxide concentrations reached a record of 407.4 parts per million during 2018, the study found. That is 2.4 ppm greater than 2017 and "the highest in the modern instrumental record and in ice core records dating back 800,000 years," the report said, according to CNN.
It wasn't just the amount of carbon dioxide that set record levels. Other greenhouse gases like methane and nitrous oxide also continued a rapid rise into the atmosphere. Together, the global warming power of greenhouse gases was 43 percent stronger than in 1990, according to the State of the Climate report released Monday by the American Meteorological Society, a division of the National Oceanic and Atmospheric Administration's (NOAA) National Centers for Environmental Information.
