More May Than April: First Taste of Summer Arrives This Weekend

Weekend Weather May Leave You Giddy

It may be something I ate but I do feel odd; a faint whiff of optimism perhaps? More people are getting vaccinated, temperatures will soon mellow into the 70s, and I did stay at a Holiday Inn Express last night. Not sure. It's an unfamiliar yet welcome feeling.

Suddenly spring is on fast-forward: a race to get docks and boats in the water (6 month boating season this year?) It's almost as though Mother Nature flipped a switch. Cue the color green.

Dry weather spills into most of Monday with a taste of early May: 3 or 4 days of 70s are likely. No records expected, but daytime highs may run 20F above average the first week of April.

A thunderstorm could pop up late Monday, with steadier, heavier rain Tuesday night into at least Thursday, tapering as showers Friday. Apologies to Twins fans hoping to enjoy a dry Home Opener next Thursday. Let's hope the storm shifts course.

Then again, we need the rain. Severe to extreme drought is gripping the Dakotas.

Odds may favor a hotter, drier summer this year.

It May Feel Like May This Weekend. After a couple of chilly, windblown days, I'm happy to be tracking a (real) warm front for the weekend and first few days of next week. Temperatures cool by midweek, but still run well above normal through the foreseeable future.

Blocking Pattern = Lingering April Warmth. With a massive ridge of high pressure stalled over the Great Plains and Rockies I don't see much chance for a volley of cold fronts anytime soon. Part of me wonders if Mother Nature is tipping her hand for the summer: hotter and drier for the central USA? We will see, but we are probably due for a stinking hot summer.

CoreLogic: Southeast Tornado Outbreak Affected Nearly 10,000 Homes. Insurance Journal has details: "Nearly 10,000 homes were impacted by tornado damage that occurred across Alabama and Georgia last week, according to data from catastrophe modeling firm CoreLogic. The March 25 deadly tornado outbreak occurred thanks to prime weather conditions that produced what is known as "supercell" storms that produce the most tornadoes, CoreLogic said. Southern states were rocked by the destructive tornadoes that claimed the lives of 5 people. The severe weather outbreak was especially dangerous due to long-tracked tornadoes – one of which extended for 100+ miles alone, according to CoreLogic's Tornado Verification Technology..."

Fancier Homes Mean Higher Insurance Premiums Under New Flood System. Bloomberg Green has the details: "The Federal Emergency Management Agency on Friday unveiled the details of an overhaul to its beleaguered National Flood Insurance Program, the initiative's first major update in 50 years. Most homeowners in the program will have lower or stable premiums, but roughly 11% of homes—largely the highest value ones—will see increases in premiums of at least $10 a month. Those could continue to rise until they reach a cap of $12,000 a year. The NFIP serves roughly 5 million homes, most of which are in high-risk flood areas. Premiums have risen steadily over the years, and yet the program is more than $20 billion in debt, in part because of climate change-related phenomena such as sea-level rise and increased storms and heavy precipitation events, which lead to more intense and more widespread flooding..."

How Cargo Ships Could Detect Tsunamis. I didn't see this coming. Check out a fascinating post at WIRED.com (paywall): "...Hossen, Sheehan, and their colleagues modeled how well a cargo-ship-based sensing array might actually work. Hossen is the first author on their paper published in Earth and Space Science in February, evaluating ship-borne GPS tsunami forecasting in the Cascadia subduction zone via a computer simulation. Given the region's steady vessel traffic, the researchers used actual ship coordinates supplied by the global data and analytics provider Spire. While marine traffic typically follows similar routes, the number and spatial distribution of ships varies, which the simulation took into account. The study also simulated tsunami-produced variations in ship elevation and velocity. The team used data assimilation, a technique that combines observations with a numerical model to improve predictions, in order to forecast the virtual tsunamis..."

Air Pollution Puts Children at Higher Risk of Disease in Adulthood. ScienceDaily has a summary of a troubling new study: "Children exposed to air pollution, such as wildfire smoke and car exhaust, for as little as one day may be doomed to higher rates of heart disease and other ailments in adulthood, according to a new Stanford-led study. The analysis, published in Nature Scientific Reports, is the first of its kind to investigate air pollution's effects at the single cell level and to simultaneously focus on both the cardiovascular and immune systems in children. It confirms previous research that bad air can alter gene regulation in a way that may impact long-term health — a finding that could change the way medical experts and parents think about the air children breathe, and inform clinical interventions for those exposed to chronic elevated air pollution..."

We Sampled Tap Water Across the U.S. - and Found Arsenic, Lead and Toxic Chemicals. The Guardian has an analysis of water around the nation, which may not be a clean and chemical-free as we had hoped: "...Since the passage of the Clean Water Act in 1972, access to safe water for all Americans has been a US government goal. Yet millions of people continue to face serious water quality problems because of contamination, deteriorating infrastructure, and inadequate treatment at water plants. CR and the Guardian selected 120 people from around the US, out of a pool of more than 6,000 volunteers, to test for arsenic, lead, PFAS (per- and polyfluoroalkyl substances), and other contaminants. The samples came from water systems that together service more than 19 million people. A total of 118 of the 120 samples had concerning levels of PFAS or arsenic above CR's recommended maximum, or detectable amounts of lead..."

Covid-19 PPE Litter is Killing Wildlife. CNN.com reports: "Waste from lifesaving personal protective equipment (PPE) is killing birds, fish and other wildlife across the globe, a study has found. Animals are fatally ingesting or becoming entangled in discarded latex gloves and disposable face masks, while others have started building their homes using the same material, researchers said. "As always with these single-use items, you're not really looking after them and they end up in the environment really soon. They start becoming a real problem," Auke-Florian Hiemstra, a biologist at the Naturalis Biodiversity Center in Leiden and co-author of the report, told CNN Tuesday. "I think it's ironic that the materials that protect us are so harmful to the animals around us," Hiemstra added..."

How mRNA Technology Could Change the World. An inflection point with quickly-engineered vaccines for a variety of virulent threats? The Atlantic explains: "...But mRNA's story likely will not end with COVID-19: Its potential stretches far beyond this pandemic. This year, a team at Yale patented a similar RNA-based technology to vaccinate against malaria, perhaps the world's most devastating disease. Because mRNA is so easy to edit, Pfizer says that it is planning to use it against seasonal flu, which mutates constantly and kills hundreds of thousands of people around the world every year. The company that partnered with Pfizer last year, BioNTech, is developing individualized therapies that would create on-demand proteins associated with specific tumors to teach the body to fight off advanced cancer. In mouse trials, synthetic-mRNA therapies have been shown to slow and reverse the effects of multiple sclerosis. "I'm fully convinced now even more than before that mRNA can be broadly transformational," Özlem Türeci, BioNTech's chief medical officer, told me..."

Climate Stories....

How Biden's Infrastructure Plan Will Address Climate Change. TIME.com has more details: "...None of that is to say the proposal is light on dedicated climate proposals. The Administration calls for $174 billion to help advance domestic production of electric vehicles and $35 billion for climate-related research and development, for example. Those big ticket items sit alongside smaller but significant proposals like the creation of a Civilian Climate Corps that would create jobs by employing people to conserve public lands and the start of a new program to hire people to plug oil and gas wells across the country. The value alone of these climate-focused programs—easily totaling in the hundreds of billions of dollars—would make the American Jobs Plan the biggest ever single U.S. investment in tackling climate change..."

How Biden Plans to Tackle the Climate Crisis in His $2 Trillion Infrastructure Plan. Vox.com provides additional perspective on how the president's infrastructure plan will address climate change: "...It will also build off of the American Rescue Plan to revive the nation's struggling public transit, which will help keep polluting cars off the roads. $85 billion will be put toward repairing existing buses, light rail, and other transit lines. Not all of the plan's transportation investments will be explicitly green, though; a chunk of the funds will also go to maintaining roads and highways. For the second-largest contributor to the US carbon footprint — the power sector — the plan proposes establishing a Clean Electricity Standard. The policy would mandate utilities across the country to increase their share of clean electricity. Along with the expanded 10-year tax credits for renewable energy in the plan, it would be a key tool to get the nation to Biden's goal of 100 percent carbon-free electricity by 2035..."

Global Forest Losses Accelerated Despite the Pandemic, Threatening World's Climate Goals. The Washington Post (paywall) reports: "The loss of forests critical to protecting wildlife and slowing climate change accelerated during 2020, despite a worldwide pandemic that otherwise led to a dramatic drop in greenhouse gas emissions, a global survey released Wednesday has found. The Earth saw nearly 100,000 square miles of lost tree cover last year — an area roughly the size of Colorado — according to the satellite-based survey by Global Forest Watch. The change represents nearly 7 percent more trees lost than in 2019..."

Warming Baseball Season. Climate Central takes a look at the ongoing warming trend during the MLB season: "Opening day is tomorrow, and the baseball season is warming up due to climate change. Since 1970, Major League Baseball (MLB) cities have warmed an average of 2.1°F during the baseball season. The greatest warming occurred in Toronto for the Blue Jays (warmed by 5.2°F) while the least occurred in Oakland, California for the Athletics (cooled by only 0.1°F). As temperatures increase, so does the frequency of heavy rain events and bouts of extreme heat—weather conditions which can postpone games and impact the health of players and fans. And for baseball stats enthusiasts, it can also affect the probability of home runs. MLB has taken strides to become more green and sustainable in recent years, including LEED (Leadership in Energy and Environmental Design)-certified stadiums, LED field lights, solar energy use, and more..."

"Immediate and Drastic". The Climate Crisis is Seriously Spooking Economists. Never a good thing to spook economists worried about a house of cards climate scenario. CNN.com has the story: "Worsening inequality, trillions of dollars in economic damage and depressed economic growth. Those are the outcomes that economists fear we will face unless the world aggressively confronts the climate crisis. Nearly three-quarters (74%) of economists agree "immediate and drastic" action is warranted to curb emissions, according to a survey released Tuesday from the Institute for Policy Integrity at the NYU School of Law. That's up sharply from 50% in 2015. Since that time, the United States has been hit by an onslaught of extreme and deadly weather events including Hurricane Maria, massive wildfires in California and this year's deep freeze in Texas..."

Vatican Calls for Action to Assist People Displaced by Climate Change. The Catholic Sun reports: "Whether people admit it or not, climate change and environmental destruction are forcing millions from their homes, and Catholics have a responsibility to assist them, Pope Francis wrote in the preface to a new document. "When people are driven out because their local environment has become uninhabitable, it might look like a process of nature, something inevitable," the pope wrote. "Yet the deteriorating climate is very often the result of poor choices and destructive activity, of selfishness and neglect, that set humankind at odds with creation, our common home." The papal preface appears in "Pastoral Orientations on Climate Displaced People," a document released March 30 by the Migrants and Refugees Section of the Dicastery for Promoting Integral Human Development..."
