Himalaya Glaciers are Growing

Over the past few years there have been a number of news articles about the imminent disappearance of all the glaciers in the Himalayas. I won’t go into the detail of the IPCC report that predicted their demise by the year 2035, but it did happen. All of this is silly because that is not how the Earth’s climate behaves. Every source of climate information in the Northern Hemisphere shows that the Earth experienced the warmest climate of the last 100,000 years bout 6,000 years ago and since then (especially over the past 4,000 years) the Northern Hemisphere has been experiencing a gradual cooling. That does not mean that each century is colder than the one before, but it means that each millennium is colder than the one before.

2011 Northern Hemisphere: Snow Coverage Part 2

Part 2 is going provide some seasonal and regional detail that was not covered in Part 1 in the discussion of the NH snow coverage. One of the things I am trying to show in these articles is how normal it is for certain parts of the world to experience a mild (low snow) winter while others are experiencing a harsh (more snow) winter. This year has made headlines by being unusually mild in the United States, but that is one of the only regions that is experiencing a mild winter this year, but the discussion of 2012 remains an article for the future.

2011 Northern Hemisphere: Snow Coverage Part 1

The back and forth in the global warming debate about snow coverage is always amusing. The debate has stated both that snow will increase or decrease because of global warming. Both news stories get coverage almost simultaneously because every year there are some places that get more snow than average, while others get less than average. All a person needs to do is Google global warming, snow and let the conflicting stories and news articles paint the funny picture.

Tracking the Progression of the Autumn Snow

As Fall progresses I have been keeping an eye on the progress of the yearly snowfall. I use several methods to track this and have found an interesting disagreement between the methods. One measure is the snowpack which is a measure of how deep the snow is where the snow is located. The other is the snow extent which is how much area is covered by snow. The sources I use for the two measures are:
