Misleading: The temperature effect of this low so

Misleading: The temperature effect of this low solar activity is primarily felt in the far upper reaches of the outer atmosphere, and is not expected to have any effect on the surface temperatures we experience.

Fails to grasp significance of observation: A low point ("minimum" in the normal 11-year solar activity cycle is not equivalent to a prolonged "grand minimum" like the Maunder Minimum that lasted from the mid 1600s to the early 1700s.

KEY TAKE AWAY

Observations have shown that solar flare activity on the surface of the Sun is in the quiet phase of its continuing 11-year cycle. This causes cooling of the thermosphere—a layer of the atmosphere that starts 65 miles above the surface—and will not cause noticeable cooling at the surface.

SCIENTISTS' REVIEW

CLAIM: "Humanity could soon face a long, cold winter which could see temperatures across the planet plunge to depressing lows.

A Nasa scientist who [sic] fears sunspot activity on the surface of our star has dropped to a new low.

It’s feared this could herald the arrival of a uniquely grim ‘mini Ice Age’.

‘We see a cooling trend,’ Martin Mlynczak of Nasa’s Langley Research Center told Space Weather."


UPDATE (22 Nov. 2018):
This article was updated after this review was published. The author completely changed the title and the main claim of the article, making it clear that no mini ice age would be imminent, and appended an update statement. See details below.

Martin Mlynczak, Senior Research Scientist, NASA Langley Research Center:

The claims such as those in the Metro article are false. If you check the original story at Space Weather [the source of the quotes], there is no mention of a mini ice age, nor is there any mention of consequences for weather and climate at Earth’s surface.

To emphasize, the cooling effects we are seeing in Earth’s thermosphere are a result of the current solar minimum conditions. The thermosphere is the layer of Earth’s atmosphere beginning 65 miles above Earth’s surface and is highly sensitive to solar activity.

There is no relationship between the natural cycle of cooling and warming in the thermosphere and the weather/climate at Earth’s surface. NASA and other climate researchers continue to see a warming trend in the troposphere, the layer of atmosphere closest to Earth’s surface.

There is no inconsistency between the science findings of a warming troposphere [where we live] and the Thermosphere Climate Index described above in the Space Weather article.
