Global Warming in My Lifetime – July’s Story

NASA GISS has a great web application that let’s users generate  maps of global monthly temperature anomalies in 2 degree grids.  I’ve made a 27 second video of 7 decade maps for July to see how global temperature anomalies have progressed through my life so far.

Here’s the link to NASA GISS’s map application page. It’s very easy to use.

My video shows 7 maps, each showing the July average for each of the 16,200 grid cells (2×2 lat/lon).

Tracking JAXA Arctic Sea Ice Extent Trends

See my Arctic Update Page for daily updates on Arctic Sea Ice Extent

Arctic Sea Ice Extent (SIE) follows an annual cycle, with maximum levels usually in March and minimum values in September.  Many analysts use day-of-year charts to compare the SIE cycle by years so that they can assess the current years trend with previous years. In this post, I present an alternative to the day-of-year chart which shows the daily values a calendar month previous years and the current year.

Arctic Sea Ice Extent (SIE)

I have discussed Arctic Sea Ice Extent (SIE) here and here. Both of those posts used the NSDIC monthly Arctic SIE data. In this post, I use the Japan Aerospace Exploration Agency (JAXA) daily data series, available at this link.

Here’s the JAXA day-of-year chart . Click image to enlarge.

Gulf of Mexico Oil: Visualizations of Sea Floor Situation – Update 3

Like many others, I am trying to keep up with the Gulf of Mexico situation, particularly efforts to stop to flow of oil from the damaged 5,000 foot long riser line. I have found it difficult to get a realistic picture of the situation on the seabed floor, 5,000′ below the Gulf surface.

I will be posting what I find here.

BP continues to try to capture oil release from the sunken riser.  Here’s a  BP graphic showing their Riser Insertion Tube approach.
