Climate Crisis: Another Perspective

Why Apocalyptic Claims About Climate Change Are Wrong Few have underscored the threat more than student climate activist Greta Thunberg and Green New Deal sponsor Rep. Alexandria Ocasio-Cortez. The latter said, “The world is going to end in 12 years if we don't address climate change.” Says Thunberg in her new book, “Around 2030 we will be in a position to set off an irreversible chain reaction beyond human control that will lead to the end of our civilization as we know it.” ........... no credible scientific body has ever said climate change threatens the collapse of civilization much less the extinction of the human species ......... It’s not like climate doesn’t matter. It’s that climate change is outweighed by other factors. Earlier this year, researchers found that climate “has affected organized armed conflict within countries. However, other drivers, such as low socioeconomic development and low capabilities of the state, are judged to be substantially more influential.”............... but it’s also true that economic development has made us less vulnerable, which is why there was

a 99.7% decline in the death toll from natural disasters since its peak in 1931.

.......... In 1931, 3.7 million people died from natural disasters. In 2018, just 11,000 did. And that decline occurred over a period when the global population quadrupled. ........ IPCC estimates sea level could rise two feet (0.6 meters) by 2100. Does that sound apocalyptic or even “unmanageable”? ......... Consider that one-third of the Netherlands is below sea level, and some areas are seven meters below sea level. You might object that the Netherlands is rich while Bangladesh is poor. But

the Netherlands adapted to living below sea level 400 years ago.

............ Humans today produce enough food for 10 billion people, or 25% more than we need ........ The United Nations Food and Agriculture Organization (FAO) forecasts crop yields increasing 30% by 2050. And the poorest parts of the world, like sub-Saharan Africa, are expected to see increases of 80 to 90%. ............ Wheat yields increased 100 to 300% around the world since the 1960s, while a study of 30 models found that yields would decline by 6% for every one degree Celsius increase in temperature............. Rates of future yield growth depend far more on whether poor nations get access to tractors, irrigation, and fertilizer than on climate change, says FAO.......... By 2100, IPCC projects the global economy will be 300 to 500% larger than it is today. Both IPCC and the Nobel-winning Yale economist, William Nordhaus, predict that warming of 2.5°C and 4°C would reduce gross domestic product (GDP) by 2% and 5% over that same period............. Climate change may threaten one million species globally and half of all mammals, reptiles, and amphibians in diverse places like the Albertine Rift in central Africa, home to the endangered mountain gorilla.......... Of the 10 variables that influence fire, “none were as significant… as the anthropogenic variables,” such as building homes near, and managing fires and wood fuel growth within, forests......... “If you want to minimize carbon dioxide in the atmosphere in 2070 you might want to accelerate the burning of coal in India today,” MIT climate scientist Kerry Emanuel said. ......... “It doesn’t sound like it makes sense. Coal is terrible for carbon. But it’s by burning a lot of coal that they make themselves wealthier, and by making themselves wealthier they have fewer children, and you don’t have as many people burning carbon, you might be better off in 2070.” .........

the extreme rhetoric is making political agreement on climate change harder.

....... “We shouldn’t be forced to choose between lifting people out of poverty and doing something for the climate.” ....... Happily, there is a plenty of middle ground between climate apocalypse and climate denial.

Tesla Cybertruck Unveil

Why is it called a cybertruck? Why not simply a truck? Is it because it is a lot of software with a little bit of metal and glass thrown in?





Meet the Cybertruck, Tesla's Ford-Fighting Pickup Elon Musk has revealed the latest Tesla model, promising hundreds of miles of range for about $40,000. ....... the top-of-the-line variant, starting at $69,900, will go more than 500 miles between charges, hit 60 mph in under 3 seconds, tow up to 14,000 pounds, and start production in late 2022. ..... Musk spoke to the importance of entering the pickup segment, one of the most popular in the US....... for unclear reasons, it’s bulletproof, at least to a 9-millimeter handgun...... Pickup trucks make up roughly 15 percent of US vehicle sales, a share that has steadily grown since 2009 .......

The Ford F-150 has been the top-selling passenger vehicle in the US for 36 years straight; Americans buy nearly a million every year.

... General Motors nets, on average, $17,000 per pickup. ...... On high-end models with the sorts of options that push sale prices above $100,000, that margin can reach $50,000. ...... The large, expensive vehicles accommodate large, expensive batteries better than a compact sedan does....... Pickup customers are less likely to live in an apartment building than a single-family house where they can install a home charger. On the other hand, public charging infrastructure is hardly developed in the middle of the country where pickups are especially popular. ........ Pickup buyers.. hardly consider fuel economy when shopping. They care about capability and reliability. Plus, compared with other drivers, they’re particularly loyal to their brands of choice.......... For the Cybertruck to succeed the way the Model 3 has, Tesla must steal the customers Ford, GM, Chrysler, and other automakers most value. ....... The Roadster, Model S, Model X, and Model 3 also hit the market well after Musk’s targets. Once they did, they came off the line slowly and with problems.

Tesla Cybertruck: Impressive Specs, Killer Price, Polarizing Looks What was revealed has some damned impressive claimed specs — pretty close to Musk’s boasts that it needs to be better than a Ford F-150 and a Porsche 911 — and a price that made the audience gasp. What was revealed also looks like a 32-bit rendering of that truck you tried to doodle in class before you remembered that you’re bad at drawing. It’s a very interesting mixed bag....... The internet is already full of memes based on the looks of the Cybertruck, because the internet remains undefeated. Musk’s “armored personnel carrier from the future” looks like what the Ghost of Video Games Past drives........ the Cybertruck is bulletproof. Tesla claims the 30-times cold-rolled steel body can withstand a 9 mm bullet fired from 10 meters away........ After dropping metal balls from varying heights on sample pieces of traditional car glass (shattered right away) and the Cybertruck’s “armor glass” (never broke), Musk had Tesla chief designer Franz von Holzhausen throw one of the metal balls at the windows of the Cybertruck on stage. Twice. And each time, the window cracked significantly. Musk was quick to point out that nothing broke into the cabin, and joked about fixing it “in post,” but it was an extremely awkward and deeply funny moment that is going to be replayed on TV and online again and again........ we’re still waiting for the new Roadster two years after its reveal
