The Physics of Materials at Minus 80 Degrees Celsius

If you know two corresponding temperature values in both °C and °F, you can set up an equation that converts from Celsius to Fahrenheit.You can also use your basic algebraic skills to change this into an equation that takes the temperature in Fahrenheit and converts to Celsius.

In an Odd Twist, Cleaner Air in China May Mean a Warmer Earth

In an Odd Twist, Cleaner Air in China May Mean a Warmer Earth

In fact, China’s push to continue cleaning up its air in the future could warm the entire northern hemisphere by 0.1 degrees Celsius by the end of the century, making it even tougher to keep the Earth’s temperature below the 1.5 Celsius degree (2.7 degrees Fahrenheit) warming limit that scientists say is necessary to avoid severe weather disruptions, increased rainfall, sea level rise, droughts, and other disastrous climate change effects by the year 2100.

Inside the Icelandic Facility Where Bitcoin Is Mined

The abundant water and underground heat is harnessed by hydroelectric dams and geothermal power stations to produce cheap, green electricity that facilitates the energy-intensive process of confirming cryptocurrency transactions—called mining, since miners are rewarded for their efforts with newly minted and extremely volatile “coins.” The fact temperatures rarely top 57 degrees Fahrenheit also helps.

China’s Moon Lander Wakes Up From Its Long, Ultra-Cold Night

But yesterday, China’s space agency announced that the frigidity of the lunar night is even more intense than we’d thought: The country’s Chang’e 4 spacecraft recorded an icy low of –310 degrees Fahrenheit (–190 degrees Celsius).

The Finnish Swimmers Who Chill Out in Subzero Temperatures

Photographer Markku Lahdesmaki came across this scene while visiting Rauhaniemi beach on Nasijarvi Lake a few Januaries ago. "I felt like I couldn't breathe." Avanto—Finnish for "hole in the ice"—is a national pastime in Finland between November and March, when temperatures drop as cold as -35 degrees Fahrenheit.

In response, we’re beginning a new feature that looks at steps individuals can take to reduce their carbon footprint.We start in the kitchen, with the elephant in the room: the refrigerator.Recommendations vary slightly among government agencies and consumer groups, but the proper temperature for a household refrigerator is 37 to 40 degrees Fahrenheit (3 to 4 degrees Celsius).

The Bugs Are Coming, and They’ll Want More of Our Food

The Bugs Are Coming, and They’ll Want More of Our Food

Worldwide, insect pests consume up to 20 percent of the plants that humans grow for food, and that amount will increase as global warming makes bugs hungrier, according to a study published Thursday in the journal Science.That could encourage farmers to use more pesticides, which could cause further environmental harm, scientists said.For every degree Celsius (two degrees Fahrenheit) that temperatures rise above the global historical average, the amount of wheat, corn, and rice lost to insects will increase by 10 to 25 percent, the study says.

And it is lowest in the morning."A temperature of 99 at six o’clock in the morning is very abnormal, whereas that same temperature at four o’clock in the afternoon can be totally normal," says Jonathan Hausmann, a rheumatologist at Boston Children’s Hospital and Beth Israel Deaconess Medical Center in Boston, who gathered 11,458 temperatures in crowdsourced research using an iPhone app called Feverprints.The study, published online this month in the Journal of General Internal Medicine, refutes the age-old benchmark of 98.6 degrees Fahrenheit.
