Clearly the warming trend continues worldwide, despite an ultra-normal summer for Southern California, and one only has to piece together the fires in Russia and extreme heat in Europe and the Eastern Seaboard of the US, flooding in New England and the southern midwest, and now, disastrously, Pakistan, to see the warming trend manifesting worldwide.

See: “Heat Records Broken in 17 Countries so far this Year,” By Andrew Freedman, Climate Central
“These nations comprise 19 percent of the total land area of Earth. This is the largest area of Earth’s surface to experience all-time record high temperatures in any single year in the historical record. Looking back at the past decade, which was the hottest decade in the historical record, 75 countries set extreme hottest temperature records (33 percent of all countries.) For comparison, fifteen countries set extreme coldest temperature records over the past ten years (six percent of all countries).”
“The climate is changing,” said Jay Lawrimore, chief of climate analysis at the National Climatic Data Center in Asheville, N.C. “Extreme events are occurring with greater frequency, and in many cases with greater intensity.”
He described excessive heat, in particular, as “consistent with our understanding of how the climate responds to increasing greenhouse gases.”
