The seasons first real heat wave in the Northeast and Mid-Atlantic is about to arrive with heat indexes over 100 by mid-week from Boston to Baltimore and Washington. It will be a drastic change for those in the Northeast U.S. since it was unusually cool last weekend. Here in Maryland, temperatures were in the upper 40’s at sunrise Monday, but it will not last! Highs will reach the mid 90’s by Thursday afternoon with a dramatic increase in humidity.
Perhaps the most telling statistic of all is from Steve Scolnik over at Capital Climate. All 13 May’s this century were in the top 14 on record. It highlights just how ridiculous the claim that the planet has stopped warming really is. If anyone tells you this line, you are being give political propaganda and not science.
Just how unusually warm has this spring been? Take a look at the chart below for Baltimore. Every year of record is plotted. Click the image for a larger view.
