climatedigest

Overview

Each month, we will provide information regarding the previous month’s climate. July 2015 was the warmest July on record, with the combined average global land and ocean temperature at 1.46° Fahrenheit, or 0.81°Celsius, above the 20th century average.

Highlights Dataset

Dataset: 20150821 EarthNow: July 2015 Highlights

Dataset: 20150821 EarthNow: AUDIO July 2015 Highlights

 

This dataset shows some of the major June weather and climate highlights from the National Climatic Data Center’s (NCDC) monthly global climate analysis, and serves as an overview of what can be discussed in the datasets that follow. Highlights are noted below.

 

  • Typhoon Nangka: Warm waters of the West Pacific Ocean contributed to the formation of Nangka on July 3rd, which later made landfall in Japan, causing flooding rains and two fatalities.
  • Australia: A significant cold outbreak occurred during the middle of the July resulting in widespread snowfall over parts of New South Wales and Queensland.
  • Europe: Two extreme heat waves dominated the weather across Europe.
  • Africa: The average temperature for Africa was the second highest for July on record, behind only 2002, with regional record warmth across much of eastern Africa.
  • South America: For the Continent, July 2015 was the 5th warmest July ever recorded.
  • United States: The average U.S. temperature for July was 73.9 degrees Fahrenheit, or two-tenths above the 20th century average, resulting in the month ranking near the median. Meanwhile, drought conditions worsened across the Pacific Northwest and in parts of the Southeast.
  • Hurricane Dolores: Brought heavy rains to southern California, Nevada, and New Mexico.

Sea Surface Temperature Anomalies Dataset

Dataset: 20150821 EarthNow: July 2015 SST Anomaly

Dataset: 20150821 EarthNow: AUDIO July 2015 SST Anomaly

 

 

  • The real-time sea surface temperature anomaly dataset is a great way to visualize the El Niño – Southern Oscillation (ENSO) in the eastern Pacific Ocean.
  • The global sea surface temperature for July 2015 was the highest on record at 1.35° Fahrenheit (0.75° C) above the 20th century average.
  • According to NOAA’s Climate Prediction Center, strong El Niño conditions were present during July 2015. There is a greater than 90 percent chance that El Niño will continue into the Northern Hemisphere winter and an 85 percent chance it will last into spring 2016.
  • Remember blues indicate cooler than average temperatures and reds indicate warmer than average temperatures (white: average).

Snow and Ice Cover Dataset

Dataset: 20150821 EarthNow: July 2015 Snow and Ice Cover

Dataset: 20150821 EarthNow: AUDIO July 2015 Snow and Ice Cover

 

 

  • Aside from helping to illustrate seasonal changes, the real-time Snow and Ice Cover dataset is a great way to convey sea ice change through time, including discussing how the current sea ice extent compares to other noteworthy years.
  • The Arctic sea ice extent for June 2015 was 9.5% below the 1981-2010 average, making it the 8th smallest July sea ice extent since satellite records began in 1979.
  • In Antarctica, the sea ice extent was 3.8% above the 1981-2010 average, the 4th largest on record for the month of July.

Where do I find the datasets?
      • First, check your SOS system to make sure it’s not already in the EarthNow category.
      • In addition to the normal files, there is now a “digest” section. This section in the file structure has all of the normal files compiled into one video.
      • If not, you can download the datasets and playlist files from this FTP Site.
      • Then download and use playlist files at the top of the page (or create your own) and make sure they are in /home/sos/sosrc or /home/sosdemo/sosrc.

The State of our Lakes

climatedigest

Overview

Seen from space, Earth is a beautiful blue sphere. Take away the clouds and you’ll discover that 71% of the surface is covered by water. Looking a little closer you’ll see that just 3% is freshwater from lakes, glaciers, and ice caps. Of that 3%, just a quarter of a percent comes from freshwater lakes.

Freshwater lakes are a valuable resource that provide an important sense of place to people and communities. Data from buoys and satellites show that our lakes are warming, and the effects of warming lakes can cause serious problems to the ecosystems of those lakes.

About the Dataset

Dataset: 20150818 EarthNow: AUDIO The State of our Lakes

This dataset shows satellite and buoy data documenting the warming of surface waters in freshwater lakes and the effects of recent warming. These effects range from changing aquatic species, lack of nutrients in lake water, and Harmful Algal Blooms.

 

  • Section 1: From small fishing ponds to Great Lakes all over the world, freshwater lakes are precious resources that provide an important sense to people and communities.
  • Section 2: A recent NASA study shows that 95% of 167 inland freshwater lakes from all over the world have warmed by as much as 4°Fahrenheit(2.2°C) over a 24 year period(1985-2009).
  • Section 3: The Laurentian Great Lakes are warming, but what is more intriguing is that the largest and deepest of the lakes, Lake Superior has warmed the most.
  • Section 4: Warmer weather is leading to earlier lake ice melt and earlier stratification.
  • Section 5: Another cause for concern with warmer lakes is increased algae production with more potential for Harmful Algal Blooms.
