Heat wave in early July 2010 / Hitabylgjan í byrjun júlí 2010

Víða í BNA og Evrópu var óvenju heitt í byrjun júlí. Kortið hér að neðan sýnir hitastigs-frávik fyrir vikuna 4 – 11 júlí 2010, samanborið við sömu dagsetningar árin 2000 – 2008.

Nýleg rannsókn vísindamanna við Stanford háskóla bendir til þess að í BNA verði hitabylgjur algengar og langvarandi innan 30 ára (http://www.eurekalert.org/pub_releases/2010-07/su-hwc070810.php).

In parts of USA and Europe early July was unusually hot. The map below shows the temperature anomaly for the week of 4 – 11 July 2010, compared to the same dates in 2000 – 20008.

Recent studies by scientists at Stanford suggest that long heat waves will be common within the next 30 years (http://www.eurekalert.org/pub_releases/2010-07/su-hwc070810.php).
