What Is Climate Change? (VIDEO)

Remember the difference between weather and climate? We know what happens when the weather changes—it’s obvious. Climate is another story. Read on. When it rains, you put on a raincoat or take your umbrella when you go out. It snows: time for high boots, a heavier coat, scarf, and warm gloves. And sunny days, well,

Weather And Climate — Similarities & Differences

Weather and climate are similar but different. For the most part, they are very distinct phenomena. Below, we talk about the weather first, and then delve into the climate. Weather We measure what’s going on in our atmosphere over a short period of time—usually in a particular place on a particular day—by assessing the weather. Could be

Climate Synthesis Sent To World Leaders By IPCC

Or do you? It’s time to pay attention to climate change now—as if it wasn’t back in 1800, when our current problems started. We all need to acknowledge that stunning industrial achievements can carry with them enormous unforeseen risks and challenges. Americans should take particular note, because on the whole we are wa-a-a-y behind on this.

May Snow, Two Days Before Mother’s Day?

Wait a minute—isn’t Mother’s Day on Sunday? Rusty Dawkins tweets this pic of about six inches of May snow in a Rushville, Nebraska back yard. Becky Kellogg of tells us: May snowfall is nothing unusual for the Rocky Mountains, but pretty much everywhere else, it’s rare. One of the more recent May snowstorms outside

Food Safety When Bad Holiday Weather Means Late Or No Guests

If you must postpone a holiday feast, keep it fresh and safe! (Gavin St. Ours, Flickr creative commons). Whatever your menu, you always need to watch out when guests are late or don’t arrive how you preserve the freshness and safety of your special feast. Let’s assume you’re serving a standard holiday meal: turkey, gravy,

Greenland 2012 Record Breaking Ice Melt Driven By Thin Clouds

Low-level clouds usually reflect solar energy back into space, as does the white coverage of snow. The albedo of cloud and snow — it’s ability to reflect sunlight back into space — is vitally important for minimising the level of solar energy wandering around inside our atmosphere, heating up our planet. One of the fears

Ancient Arabic Histories Illuminate Past Climate

  Trees, coral, and ice cores provide us a very reliable method of looking at the past climate, but there isn’t as much human recorded data. New research has analysed scholarly writings from Iraq written during the Islamic Golden Age between 816 and 1009 AD in an effort to reveal more information about our planet’s

NASA Asks What Caused Snowmaggedon?

The winter of 2009-10 on the East Coast of the U.S. was dubbed Snowmagedon due to the massive 54.9 inches of snow that fell on the Baltimore-Washington area between December and February. NASA scientists quickly set out to discover what set of conditions allowed for such an unprecedented winter. This is one of those stories

NASA Asks Where Has All The Snow Gone?

On their science blog NASA has asked ‘What Happened To All The Snow?’ and it’s a good question, considering that the U.S. is currently experiencing a surprising lack of snow that, come spring time, may have serious consequences for communities reliant upon the snow runoff. “The Mammoth Mountain ski resort in the Sierras of California

Curry Lost in Denial (& Global Warming Still = More Snow)

I recently noticed an inane article in the Daily Mail trying to create another scandal out of climate skeptic Richard Muller’s recent finding that the climate scientists were right after all. Apparently, one of the co-authors, infamous (within climate science circles) Judith Curry was less than enthusiastic about the results. When seeing the news (in

What Will a 4 Degree Increase do to Australia

The results of research looking into what will happen to the Australian climate if and when a global increase of 4º Celsius across the world takes place was presented by CSIRO’s Dr Penny Whetton at the Four Degrees climate change conference in Melbourne.

Arctic Affected by Climate Change More than Expected

• The last five years have been the warmest since 1880 when monitoring began
• Tree ring data suggest that the summer temperatures over the past few decades have been the highest in 2000 years
• Snow cover in May and June has decrease by close to 20%
• The winter season in the Arctic has been shortened by almost two weeks
• There is worry about the decrease in snow and ice cover in the Arctic that will decrease the amount of solar radiation reflected back out into the atmosphere
• Warming is only expected to continue
• Sea level rise by 2100 is expected to be between 0.9 and 1.6 metres, approximately twice what was predicted by the UN panel on climate change

Pollutants in the Springtime Melting Snow

Spring has arrived for the northern hemisphere and the snow is beginning to melt. But according to a new study out of the University of Toronto, Scarborough (UTSC), the snow melt brings with it a massive uptick in pollutants.

That Is a Lot of Snow

For the contiguous United States of America, January saw snow reach every one of the 50 states except for Florida. The image comes courtesy of NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, showing the maximum snow cover for the month. The data shows that about 71 percent of the entire country had

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

The European Space Agency posted this image up on their Flickr page a week or so ago, showing the Apennine Mountains with their snowy peaks from space. The diverse and picturesque contours of southern Italy, known for its boot-like shape, take centre stage in this Envisat image. Its varied landscape is made up of sandy

Heavy Snow on the Korean Peninsula

In mid-February 2011, residents along South Korea’s east coast were struggling to dig out from the heaviest snowfall in more than a century. The BBC reported that hundreds of stranded motorists awaited rescue, and hundreds of homes had collapsed under the weight of heavy snow. The South Korean government had deployed 12,000 soldiers to assist
