World Time Calculator, or “Dial-a-Time”

Here’s one of the funniest ways to tell world time that I have ever seen. I call it “Dial-a-Time,” although that’s not the official name for it. (The official name is “xkcd.com/1335/”.) First of all, with this graphic you have to get used to the fact that you are looking at the world from Antarctica

Northern Hemisphere Is Becoming Warmer Than Southern Hemisphere

You may not have consciously thought about it, but I imagine that to some of you out there who have an environmentally conscientious brain, the fact that the Northern Hemisphere has more landmass and the Southern Hemisphere has more ocean would have triggered some interesting questions. For example, if there is such regional variation in

Global Temperatures 8th Warmest on Record

According to the National Oceanic and Atmospheric Administration’s latest analysis of global temperatures, October 2011 was the 8th warmest October ever recorded since 1880. NOAA’s National Climatic Data Centre provide a series of reports as part of their services to the government, business and community leaders, which have been helping everybody keep a track of

No Simultaneous Warming of Hemispheres in 20 000 Years

One of the common arguments to dismiss those supporting the idea that the climate is warming as a result of manmade carbon dioxide emissions is that global warming is a natural thing; that it has always varied and that sometimes temperatures rise and that this is a perfectly natural occurrence. However in a new study it has been shown that a simultaneous warming of both the Southern and Northern Hemispheres has never happened in the past 20,000 years.

La Nina is Back says NOAA

As climate experts had already predicted, the National Oceanic and Atmospheric Administration has announced that La Niña – which was the cause behind so much of the extreme weather towards the end of 2010 and into 2011 – has re-emerged in the Pacific Ocean and is expected to gradually strengthen and continue into the Northern Hemisphere’s winter.

Ocean Currents Speeding Melting Glaciers

New research has shown that strong ocean currents running under the West Antrarctic’s Pine Island Glacier Ice Shelf are eating away at the ice from below, contributing to the rapid decline in the shelf’s mass, thus increasing the amount of meltwater running into the oceans.

Carbon Dioxide Unlikely to Spark Abrupt Climate Change

New research into the issue of whether atmospheric carbon dioxide has the capacity to spark an abrupt climate change has shown that past changes are more likely linked to alterations in ocean circulation unique associated with ice ages, rather than a catastrophic level of atmospheric carbon dioxide.

Melting Snow and Ice Warm Northern Hemisphere

The NASA Earth Observatory Image of the Day for the 24th of February showcases just how much energy is reflected back into space by the planet’s chryosphere, and how much that amount has decreased over the past 30 years. Mark Flanner of the University of Michigan and his colleagues have used satellite data to measure

Ghostly Sea Ice Surrounds Shikotan

NASA’s Image of the Day recently showcased an image of Ostrov Shikotan (or Shikotan-to), a volcanic island at the southern end of the Kuril chain, lying along the extreme southern edge of winter sea ice in the Northern Hemisphere. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1)satellite captured this natural-color image of Shikotan on February

Warming Planet Affecting Storms Differently by Hemisphere

Global warming will have a varying effect on weather systems depending on which hemisphere they are in, according to new research from MIT’s Paul O’Gorman, who found that the warming of the planet will affect the availability of energy to fuel large-scale weather systems that occur at Earth’s middle latitudes. O’Gorman found that more intense
