"Irakli Loladze is a mathematician by training, but he was in a biology lab when he encountered the puzzle that would change his life. It was in 1998, and Loladze was studying for his Ph.D. at Arizona State University. Against a backdrop of glass containers glowing with bright green algae, a biologist told Loladze and a half-dozen other graduate students that scientists had discovered something mysterious about zooplankton."
"Zooplankton are microscopic animals that float in the world’s oceans and lakes, and for food they rely on algae, which are essentially tiny plants. Scientists found that they could make algae grow faster by shining more light onto them—increasing the food supply for the zooplankton, which should have flourished. But it didn’t work out that way. When the researchers shined more light on the algae, the algae grew faster, and the tiny animals had lots and lots to eat—but at a certain point they started struggling to survive. This was a paradox. More food should lead to more growth. How could more algae be a problem?"
"Donald Trump signed away Obama-era flood standards just weeks before Hurricane Harvey hit Texas, in a bid to get infrastructure projects approved more quickly."
"The rule, signed by former President Barack Obama in 2015, had not yet come into effect but aimed to make infrastructure more resilient to the effects of climate change, such as rising sea levels and flooding."
"Those who backed Obama's rule believed they would make people safer by putting roads, bridges and other infrastructure on safer ground, NPR reported. But Trump rescinded the rule several weeks ago in an attempt to speed up the time it takes for infrastructure projects to be approved."
"In recent days, the flooding caused by Hurricane Harvey has raised water levels in some parts of the watershed high enough to completely cover a Cadillac. The vanished wetlands wouldn’t have prevented flooding, but they would have made it less painful, experts say."
"The Harvey-wrought devastation is just the latest example of the consequences of Houston’s gung-ho approach to development. The city, the largest in the US with no zoning laws, is a case study in limiting government regulations and favoring growth—often at the expense of the environment. As water swamps many of its neighborhoods, it’s now also a cautionary tale of sidelining science and plain common sense. Given the Trump administration’s assault on environmental protections, it’s one that Americans elsewhere should pay attention to."
"Hurricane Harvey is drowning southeastern Texas for the fourth day, putting a vast area under feet of water. Experts say Harvey has been stuck longer in one place than any tropical storm in memory. That is just one of the hurricane’s extremes; the storm is off the charts by many measures. Scientific American wanted to learn why, and we asked meteorologist Jeff Masters for help."
"Friday June 17, 2017 - Near the Gulf coast, Houston is also at annual risk from hurricanes: it is now into the start of the 2017 season, which runs from June to November. Ike, the last hurricane to hit the Houston region, caused $34bn in damage and killed 112 people across several states in September 2008."
"There is little hope the situation is going to get better any time soon. Earlier this month, days after Donald Trump announced the US will withdraw from the Paris accord on climate change, a new report warned that rare US floods will become the norm if emissions are not cut."
"It t is a painful lesson of our time that the things we depend on to make our lives more comfortable can also kill us. Our addiction to fossils fuels is the obvious example, as we come to terms with the slow motion catastrophe of climate change. But we are addicted to nitrogen, too, in the fertilizers that feed us, and it now appears that the combination of climate change and nitrogen pollution is multiplying the possibilities for wrecking the world around us."
"A new study in Science projects that climate change will increase the amount of nitrogen ending up in U.S. rivers and other waterways by 19 percent on average over the remainder of the century — and much more in hard-hit areas, notably the Mississippi-Atchafalaya River Basin (up 24 percent) and the Northeast (up 28 percent). That’s not counting likely increases in nitrogen inputs from more intensive agriculture, or from increased human population."
"Our chances of keeping warming under dangerous levels by the end of this century are increasingly slim, according to two new studies published Monday in the journal Nature Climate Change."
"The first study took a statistical approach to examine likely warming scenarios by 2100, finding a less than five percent chance of holding warming below two degrees C and a less than one percent chance of keeping it under 1.5 degrees."
