Kamala Harris: ‘This July Was the Hottest Month Ever Recorded on Earth’

(CNSNews.com) - Sen. Kamala Harris sent out a Tweet on Wednesday warning that July 2019 was the hottest month ever on Earth and that glaciers are melting.

“This July was the hottest month ever recorded on Earth,” Warren said. “Glaciers are melting. Yet this Administration continues to deny climate change. Americans deserve leaders who will fight or our planet.

“I look forward to discussing the climate crisis at @CNN’s town hall September 4,” she said.

The National Oceanic and Atmospheric Administration (NOAA) is in fact reporting that July was the hottest month for what it calls “average global temperature.”

“The average global temperature in July was 1.71 degrees F above the 20th-century average of 60.4 degrees, making it the hottest July in the 140-year record, according to scientists at NOAA’s National Centers for Environmental Information,” NOAA said in a statement published on Aug. 15. “The previous hottest month on record was July 2016.

“Nine of the 10 hottest Julys have occurred since 2005—with the last five years ranking as the five hottest. Last month was also the 43rd consecutive July and 415th consecutive month with above-average global temperatures,” said NOAA.

“Record-low sea ice: Average Arctic sea ice set a record low for July, running 19.8% below average – surpassing the previous historic low of July 2012,” NOAA said.

Not all parts of the Earth were warmer than usual, however.

“Some cool spots: Parts of Scandinavia and western and eastern Russia had temperatures at least 2.7 degrees F below average,” said NOAA.

What does NOAA mean by “average global temperature”?

Here is how NOAA tries to explain it:

“The concept of an average temperature for the entire globe may seem odd. After all, at this very moment, the highest and lowest temperatures on Earth are likely more than 100°F (55°C) apart. Temperatures vary from night to day and between seasonal extremes in the Northern and Southern Hemispheres. This means that some parts of Earth are quite cold while other parts are downright hot. To speak of the ‘average’ temperature, then, may seem like nonsense. However, the concept of a global average temperature is convenient for detecting and tracking changes in Earth's energy budget—how much sunlight Earth absorbs minus how much it radiates to space as heat—over time.

“To calculate a global average temperature, scientists begin with temperature measurements taken at locations around the globe. Because their goal is to track changes in temperature, measurements are converted from absolute temperature readings to temperature anomalies—the difference between the observed temperature and the long-term average temperature for each location and date. Multiple independent research groups across the world perform their own analysis of the surface temperature data, and they all show a similar upward trend.

“Across inaccessible areas that have few measurements, scientists use surrounding temperatures and other information to estimate the missing values. Each value is then used to calculate a global temperature average. This process provides a consistent, reliable method for monitoring changes in Earth's surface temperature over time.
