Today, you can literally taste climate change.

Spain and Portugal are already suffering the impact of global warming to the point where winegrowers either cannot grow their classic grape varietals because they shrivel in the intense heat, or they have had to invest millions of euros to move their vineyards to higher ground where the vines can enjoy the air conditioning provided by the cool currents wafting through hills and mountainsides. Winegrowers testified that they cannot control the sugars in their grapes and are making wines that don't come close to expressing true varietal character (the typical taste profiles of Syrah or Chardonnay, for example), much less a sense of place, the terroir of the vine.

Extreme heat wave in Africa and Asia continues to set all-time high temperature recordsA withering heat wave of unprecedented intensity and areal covered continues to smash all-time high temperatures Asia and Africa. As I reported earlier this week, Saudi Arabia, Iraq, Chad, Niger, Pakistan, and Myanmar have all set new records for their hottest temperatures of all time over the past six weeks. The remarkable heat continued over Africa and Asia late this week. The Asian portion of Russia recorded its highest temperate in history yesterday, when the mercury hit 42.3°C (108.1°F) at Belogorsk, near the Amur River border with China. The previous record was 41.7°C (107.1°F) at nearby Aksha on July 21, 2004. (The record for European Russia is 43.8°C--110.8°F--set on August 6, 1940, at Alexandrov Gaj near the border with Kazakhstan.) Also, on Thursday, Sudan recorded its hottest temperature in its history when the mercury rose to 49.6°C (121.3°F) at Dongola. The previous record was 49.5°C (121.1°F) set in July 1987 in Aba Hamed.We've now had seven countries in Asia and Africa, plus the Asian portion of Russia, that have beaten their all-time hottest temperature record during the past two months. This includes Asia's hottest temperature of all-time, the astonishing 53.5°C (128.3°F) mark set on May 26 in Pakistan. All of these records are unofficial, and will need to be certified by the World Meteorological Organization (WMO). According to Chris Burt, author of Extreme Weather, setting six national heat records in one month is eight in one summer is unprecedented. The only year which can compare is 2003, when five countries (the UK, France, Portugal, Germany, Switzerland, and Liechtenstein) all broke their all-time heat records during that year's notorious summer heat wave. Fortunately, the residents of the countries affected by this summer's heat wave in Asia and Africa are more adapted to extreme high temperatures, and we are not seeing the kind of death tolls experienced during the 2003 European heat wave (30,000 killed.) This week's heat wave in Africa and the Middle East is partially a consequence of the fact that Earth has now seen three straight months with its warmest temperatures on record, according to NOAA's National Climatic Data Center. It will be interesting to see if the demise of El Niño in May will keep June from becoming the globe's fourth straight warmest month on record.
