National Climatic Data Center's global map of Selected Significant Climate Anomalies and Events for June 2014
Full version here.
From the National Climatic Data Center of the National Oceanic and Atmospheric Administration:
  • The combined average temperature over global land and ocean surfaces for June 2014 was the highest on record for the month, at 0.72°C (1.30°F) above the 20th century average of 15.5°C (59.9°F).
  • The global land surface temperature was 0.95°C (1.71°F) above the 20th century average of 13.3°C (55.9°F), the seventh highest for June on record.
  • For the ocean, the June global sea surface temperature was 0.64°C (1.15°F) above the 20th century average of 16.4°C (61.5°F), the highest for June on record and the highest departure from average for any month.
  • The combined global land and ocean average surface temperature for the January–June period (year-to-date) was 0.67°C (1.21°F) above the 20th century average of 13.5°C (56.3°F), tying with 2002 as the third warmest such period on record.
And there's more bad news from the U.S. Drought Monitor, over the fold.

Greg Laden explains:
The US Drought Monitor produces an assessment of drought conditions every week. The drought in California has taken a large jump over the last few days, with the highest category, “Exceptional,” jumping from 36.49% to 58.41%. At the start of the calendar year, that category was represented in California by 0%, so this is a continuation of an ongoing trend.
Laden provides graphs to put it all in context. The Drought Monitor itself provides a summary:
Increasingly, drought indicators point to the fact that conditions are not appreciably better in northern California than in central and southern sections of the state. In addition, mounting evidence from reservoir levels, river gauges, ground water observations, and socio-economic impacts warrant a further expansion of exceptional drought (D4) into northern California. For California’s 154 intrastate reservoirs, storage at the end of June stood at 60% of the historical average. Although this is not a record for this time of year—the standard remains 41% of average on June 30, 1977—storage has fallen to 17.3 million acre-feet. As a result, California is short more than one year’s worth of reservoir water, or 11.6 million acre-feet, for this time of year. The historical average warm-season drawdown of California’s 154 reservoirs totals 8.2 million acre-feet, but usage during the first 2 years of the drought, in 2012 and 2013, averaged 11.5 million acre-feet.

Given the 3-year duration of the drought, California’s topsoil moisture (80% very short to short) and subsoil moisture (85%) reserves are nearly depleted. The state’s rangeland and pastures were rated 70% very poor to poor on July 27. USDA reported that “range and non-irrigated pasture conditions continued to deteriorate” and that “supplemental feeding of hay and nutrients continued as range quality declined.” In recent days, new wildfires have collectively charred several thousand acres of vegetation in northern and central California. The destructive Sand fire, north of Plymouth, California—now largely contained—burned more than 4,000 acres and consumed 66 structures, including 19 residences.
