Proteum能源羅伯特劍杆是化學工程師在能源行業工作。羅伯特有超過20年的國際工程經驗的化工、石油和天然氣,和可再生能源……成員自2018年以來4觀點在過去的十年中,我一直住在鳳凰城,亞利桑那州。人們有時會問是什麼感覺住在這裏。我告訴他們,這是偉大的從10月中旬到4月中旬。我們有非常愉快的天氣。但它在夏天是一個完全不同的故事。從5月到9月,真的很熱。現在,我們正處在一個20天的110度+天氣。我走出幾個晚上午夜前。 The temperature was still 100 degrees. I think the low temperature that night was 97 degrees. I walk outside in the morning, and it’s already 100 degrees. When the wind blows, it’s like standing in the exhaust of an oven. There’s yardwork I have to do, but I have to take it in small increments. It only takes about 20 minutes in this heat, and I am drenched in sweat — and I am not someone who easily sweats. If I take a “cold” shower, the water coming out of the tap is over 90 degrees. Phoenix has been under a heat warning for the past three weeks. This current heatwave is record-breaking , dangerous, and getting worse. El Niño Plus Climate Change Why is this happening? The simple answer is climate change, and here in the desert I feel like we are getting a preview of things to come. But I still have friends who don’t accept that manmade climate change is real. They will (rightly) point out that this is an “El Niño year”, when a band of warm ocean water increases temperatures. That’s true, but we have always had El Niño years. What we have in addition to that is an atmospheric concentration of carbon dioxide that has grown from around 320 parts per million (PPM) in the 1970s to over 420 PPM today. Because carbon dioxide is a greenhouse gas, it is a simple scientific fact that rising carbon dioxide will trap more heat. We can debate about how much the climate might be impacted, but there’s no credible debate that there’s an impact. Once that is understood, then we can understand why the summertime temperatures in Phoenix keep rising. It wasn’t always like this. I have heard many people here say the climate was more pleasant in the 1970s. The data backs them up. The average annual high in the 1970s was at least two degrees lower in Phoenix than it is today ( source ), and the average annual low was around six degrees cooler. That may not seem like a lot, but when you consider summertime highs plus an El Niño year, it explains why we are presently breaking heat records. A Reliable Power Grid is a Lifesaver If there’s one thing to be thankful for, it’s that we don’t suffer many blackouts in Phoenix. I have never been without power for an extended period in my home. We have a nice mix of power sources, including the Palo Verde Nuclear Generating Station, which is the largest nuclear power plant in the U.S., and the 2nd largest of any U.S. power plant. A reliable power grid here is critical, because a recent study predicted that rolling blackouts in Phoenix could lead to 12,000 deaths and nearly 800,000 people being treated for heat-related illnesses. Thus, it is also really important for those who live here to know what to do if that rare blackout does impact us during a heatwave. There are potential solutions, but none are easy, and none are quick. Those two factors have prevented us from taking aggressive actions that could reverse the rising temperature trends. It’s been monsoon season here for a month, and those storms can bring some relief. But so far, it’s been bone dry. And while blackouts could leave thousands dead without air conditioning, our power grid still holds steady for now. To survive this sweltering summer, we have no choice but to blast the AC and hope we avoid disaster until October. But unfortunately, these hellish heatwaves may become Phoenix’s new normal.
