One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and

Amazing Temperature Change Over The Mid-Atlantic Friday

Here are two maps showing the temperatures at 5 Am and 4 PM. Many areas saw a rise of over 34 degrees in just a few hours today. This rapid change in temperature was made possible by two things. Ocean and elevation. At sunrise a chilly easterly wind off the cold Atlantic (where water temps are only around 42 degrees) had pushed all the way to the Blue Ridge Mountains

What Less Fog and Clouds Mean for Coastal Southern California

A new study has found that urbanization around coastal Southern California is driving fog away and causing the low clouds, crucial for providing shade and moderating temperatures in summer, to rise. This trend has important implications for ecosystems and

A new report released by the city today gives a worrisome picture of climate-related problems the New York metropolitan region will likely face this century. Temperatures are projected to rise, extreme precipitation and heat waves will be more frequent, and sea level could reach 6 feet under the worst-case scenario. The New York metropolitan region has been preparing to meet these

 FR,
Temperatures were falling the last days and it’s not only quite cold, but I catched a cold the last days. Let’s see what we can do here. Today is Friday and since I’m sitting at the airport without proper WiFi, this Friday Links post will be… lacking links. Here is your Friday!

Measuring the temperature of solar winds 

AGU Meetings [2015-01-05 16:16:13]  recommend  recommend this post  (38 visits) info

 US
The sun spews forth super-heated, charged particles, collectively called plasma, that fly out into the vacuum of space at speeds of 200 to 400 miles per second (300 to 700 kilometers per second). These waves of plasma make up the solar winds that spread across our solar system. Traveling across freezing space should suck all the heat from the plasma by the time it nears Earth, but the solar waves detected near our planet are still hot. Scientists think something is happening within the [...]

The coldest air of the winter is about to head into the Midwest and NE U.S. over the next few days. A 1058 millibar high pressure is going to drop into the Plains starting Monday and by Thursday morning, temperatures will fall below zero as far south as Southern Indiana and Pennsylvania. The images below are from a new experimental model run that NOAA is working on to improve their

There are a lot of neat creatures living in the ocean around Antarctica: not just whales, seals, and penguins! There’s quite a diversity of invertebrates (animals without backbones) living on the ocean floor. We call these benthic invertebrates. (“Benthic” means they live on the bottom.)There are several scientists at Rothera who study these benthic invertebrates, and they shared some of their animals with me. There are some animals you are probably familiar with: sea stars (or starfish), [...]

Hole Punch Clouds Over Maryland

This “Hole Punch Cloud” was spotted over Somerset County Maryland today, and the technical name meteorologists use is “Fall Streak Hole”. They are rather rare, and happen when super-cooled water in a cloud suddenly freezes. The freezing can be started by the introduction of some ice crystals and then the super-cooled water freezes, and falls out as ice crystals. Liquid water at temperatures well below freezing is actually fairly common

2014 Poised To Take Title as Hottest Year On Record 

Dan\'s Wild Wild Science Journal [2014-12-03 22:52:36]  recommend  recommend this post  (30 visits) info
It is almost certain now that 2014 will be among the hottest years on record globally. The NASA (and NOAA), numbers are showing that it will likely be the absolute hottest, but it does depend on December temperatures. It would have to be an unusually cool December globally for a record to not be reached, and that is very unlikely based on how how warm the oceans are right now.

This is the second summer that the temperatures have got pissy in July.  Our cold winter was back to the 70's and the summers are there as well.  Can't get a sun tan in my sauna! Here is a really nice temperature graph, in that it shows error bars. I like it because the error bars increase the farther back in time.  Thus, I was not imagining that the snow drifts were higher when I was
