My new video shows how Marcellus shale gas is changing economics of plastic production, increasing risks of plastic pollution and climate change.
Vox has a great video that explains how loss of sea ice in the arctic is affecting our weather.
Peter Sinclair (https://climatecrocks.com/) provides excellent video interviews with climate scientists. Here’s an interview with Asa Rennermalm of Rutgers.
NOAA’s Weather Prediction Center is forecasting up to 20-inches of rain for Texas coastal areas over next 7 days (link).
Corpus Christie and Houston are in 20+ inch total 7-day rainfall belt, New Orleans is in the 4-6 inch belt.
Here’s an ArcGIS 10.3 map of the WPC forecast to show the rain belts and Texas – Louisiana cities.
Best wishes to all in path of this major flooding event.
The Snow,Water, Ice, and Permafrost in the Arctic, or SWIPA, has released a report on their 5 year study. Highlights have been summarized in this powerful video.
I recommend Peter Sinclair’s Climate Denial Crock of the Week for those concerned about climate change.
This animated gif shows changes in annual mean temperature at 12 East Coast USA airports that had continuous daily data for the 1950 – 2015 period. The data was retrieved from Weather Underground using the R weatherData package .
11 of the 12 airports (all but JAX) show statistically significant increases in annual mean temperatures.
2016 has been a hot and dry summer in Philadelphia. Here are a few charts that summarize the 1950-2016 daily temperature and precipitation data at Philadelphia International Airport (PHL).
August 2016 warmest in 1950 – 2016 period
41 Days with maximum daily temperature was 90 or more degrees.
Very Dry Summer
It’s been a hot summer in Philadelphia so far this year. I started wondering in the global warming has anything to do with our recent spate of 90+ days.
First, lets look at the global warming situation. NASA has announced that July, 2016 is the warmest month on record (here, here). We are well on our way to the 3rd year of record breaking global temperatures.
Is there a connection between global temperature increases and our 90+ summer? To find out, I first downloaded temperature data from the Weather Underground for Philadelphia’s NE Airport. I then plotted the daily maximum and minimum temperatures for the summer months of May through yesterday.
On first glance at the chart, I was sure that I found proof that our 33 90+ days was proof that global warming has hit Philadelphia. As I dug deeper I found that the number of 90+ days varies from a low of 6 in 1978, to 41 in 2010 and a high of 43 in 1988. We are in the high end of the 6 – 43 day ranges of 90+ temperatures range of the number of 90+ days we have had in the 1975 – 2015 period.
We need to dig deeper to find links between the number of Philadelphia’s dog days of summer and global warming. I’ll be writing on this more in the comming months.
