Hard to believe we’re about halfway through August and have weather this great. The skies started off clouded over, which kept our morning temps low. Highs are maxing out in the mid 80s downtown, and the low 80s in the suburbs. Dew points were in the mid 50s today, leading to low humidity. Tomorrow the air will be almost fall-like as yet another cold front sweeps through the region. We’ll take it!

Through Tonight: Temperatures drop to the mid to upper 70s after the work day as you head outside to enjoy the weather. It will be another windows-open kind of night — skies clear out and lows bottom out around 60 downtown, and the low to mid 50s in the suburbs. Winds are around 5 mph out of the west.

Tomorrow (Friday): Things cool down even more on Friday as temperatures only reach near 80 in the city and the upper 70s in the suburbs. In come places, it’ll be a few degrees cooler than that. Dew points will be amazingly comfortable in the mid 40s. Winds shift to the northwest at 5 to 10 mph.

Almost 70 percent of global glacier loss due to human activity

A new study in the journal Science finds that 69 percent of the global glacier loss seen since 1991 has been due to human activity, mainly the emissions of greenhouse gases from fossil fuels. Going back further than that, in the period from 1851 to 2010, they found that 25 percent of the glacier loss was attributable to humans. Glacier loss is a iconic sign of a changing climate that is not only visibly striking, but also leads directly to sea level rise and fresh water shortages.
