We Stopped At Two Nuclear Bombs; We Can Stop At Two Degrees. 269

Lasrick writes Dawn Stover writes in the Bulletin of the Atomic Scientists that climate change is irreversible but not unstoppable. She describes the changes that are happening already and also those likely to happen, and compares what is coming to the climate of the Pliocene: 'Even if countries reduce emissions enough to keep temperatures from rising much above the internationally agreed-upon "danger" threshold of 2 degrees Celsius (which seems increasingly unlikely), we can still look forward to conditions similar to those of the mid-Pliocene epoch of 3 million years ago. At that time, the continents were in much the same positions that they are today, carbon dioxide levels ranged between 350 and 400 ppm, the global average temperature was 2 to 3 degrees Celsius higher than it is today (but up to 20 degrees higher than today at the northernmost latitudes), the global sea level was about 25 meters higher, and most of today's North American forests were grasslands and savanna.' Stover agrees with two scientists published in Nature Geoscience that 'Future warming is therefore driven by socio-economic inertia," and points the way toward changing a Pliocene future.

The Last Three Months Were the Hottest Quarter On Record 552

from the not-imagining-things dept.
New submitter NatasRevol (731260) writes The last three months were collectively the warmest ever experienced since record-keeping began in the late 1800s. From the article: "Taken as a whole, the just-finished three-month period was about 0.68 degrees Celsius (1.22 degrees Fahrenheit) above the 20th-century average. That may not sound like much, but the added warmth has been enough to provide a nudge to a litany of weather and climate events worldwide. Arctic sea ice is trending near record lows for this time of year, abnormally warm ocean water helped spawn the earliest hurricane ever recorded to make landfall in North Carolina, and a rash of heat waves have plagued cities from India to California to the Middle East." Also, it puts to bed the supposed 'fact' that there's been a pause in temperature increase the last 17 years. Raw data shows it's still increasing. bizwriter also wrote in with some climate related news: A new report from libertarian think tank Heartland Institute claims that new government data debunks the concept of global climate change. However, an examination of the full data and some critical consideration shows that the organization, whether unintentionally or deliberately, has inaccurately characterized and misrepresented the information and what it shows. The Heartland Institute skews the data by taking two points and ignoring all of the data in between, kind of like grabbing two zero points from sin(x) and claiming you're looking at a steady state function.

Study: People Would Rather Be Shocked Than Be Alone With Their Thoughts 333

sciencehabit writes "How much do we hate being alone with our own thoughts? Enough to give ourselves an electric shock. In a new study, researchers recruited hundreds of people and made them sit in an empty room and just think for about 15 minutes. About half of the volunteers hated the experience. In a separate experiment, 67% of men and 25% of women chose to push a button and shock themselves rather than just sit there quietly and think. One of the study authors suggests that the results may be due to boredom and the trouble that we have controlling our thoughts. "I think [our] mind is built to engage in the world," he says. "So when we don't give it anything to focus on, it's kind of hard to know what to do."

NOAA: Earth Smashed A Record For Heat In May 2014, Effects To Worsen 547

Freshly Exhumed (105597) writes with news that NOAA's latest global climate analysis is showing things are getting hotter. From the article: Driven by exceptionally warm ocean waters, Earth smashed a record for heat in May and is likely to keep on breaking high temperature marks, experts say. The National Oceanic and Atmospheric Administration Monday said May's average temperature on Earth of 15.54 C beat the old record set four years ago. In April, the globe tied the 2010 record for that month. Records go back to 1880. Experts say there's a good chance global heat records will keep falling, especially next year because an El Nino weather event is brewing on top of man-made global warming. An El Nino is a warming of the eastern tropical Pacific Ocean that alters climate worldwide and usually spikes global temperatures.

How Climate Scientists Parallel Early Atomic Scientists 440

from the politicians-see-them-as-tools-to-be-used dept.
Lasrick writes "Kennette Benedict writes in the Bulletin of the Atomic Scientists about the existential threat of climate change, and how the scientists who study and write about it are similar to the early atomic scientists who created, and then worried about, the threat that nuclear weapons posed to humanity: 'Just as the Manhattan Project participants could foresee the coming arms race, climate scientists today understand the consequences of deploying the technologies that defined the industrial age. They also know that action now to reduce greenhouse gas emissions will mitigate the worst consequences of climate change, just as the Manhattan Project scientists knew that early action to forestall a deadly arms race could prevent nuclear catastrophe.'"
