WASHINGTON — Troves of new data from a NASA probe’s close encounters with the sun are giving scientists unique insight about the solar wind and space weather more generally as the spacecraft zooms through the outermost part of the star’s atmosphere.
Researchers on Wednesday described the first published findings from the Parker Solar Probe, a spacecraft launched in 2018 to journey closer to the sun than any other human-made object. The findings, offering fresh details about how the sun spawns space weather, are reshaping astronomers’ understanding of violent solar wind that can hamper satellites and electronics on Earth.
“We were certainly hoping we’d see new phenomena and new processes when we got close to the sun — and we certainly did,” Nicola Fox, director of the U.S. space agency’s heliophysics division, told reporters. “Some of the information that we found pretty much confirmed what we expected, but some of it is totally unexpected.”
Earth is roughly 93 million miles from the sun. The probe ventured as close as 15 million miles (24 million km) to the sun to gather the data used in the studies published in the journal Nature. The probe eventually will travel within about 4 million miles (6 million km) from the sun’s surface, seven times closer than any previous spacecraft.
The probe has endured extreme heat while flying through the outermost part of the sun’s atmosphere, called the solar corona, that gives rise to solar wind — the hot, energized, charged particles that stream outward from the Sun and fill the solar system.

Oscillations in the speed of these charged particles beaming outward from the solar corona have previously been thought to dissipate gradually, much like the waves seen after plucking a guitar string fading from the middle.
One of the probe’s “really big surprises,” according to one of the researchers, was the detection of sudden, abrupt spikes in the speed of the solar wind that were so violent that the magnetic field flips itself around, a phenomenon called “switchbacks.”
“We’re finding these discrete, powerful waves that wash over the spacecraft, kind of like rogue waves in an ocean,” said Justin Kasper, a principal investigator whose team at the University of Michigan built a solar wind-sensing instrument on the Parker probe. “They carry a tremendous amount of energy.”
“This will dramatically change our theories for how the corona and solar wind are being heated,” Kasper added.

NASA has been monitoring and documenting the sudden heating up of our planet and everyone knows that global warming is Fake News and alternate facts. Oh, and don't forget those phonied-up "moon landings" ...

NASA only tells the truth when it suits our sensibilities.

The same NASA that says this:

Quote:

Global temperature records start around 1880 because observations did not sufficiently cover enough of the planet prior to that time. The period of 1951-1980 was chosen largely because the U.S. National Weather Service uses a three-decade period to define “normal” or average temperature. The GISS temperature analysis effort began around 1980, so the most recent 30 years was 1951-1980. It is also a period when many of today’s adults grew up, so it is a common reference that many people can remember.

When NASA says "Hottest Year on Record" they are saying "Hottest Year in Comparison to our 1951-1980 data set."

Canada on track to be slightly warmer than normal in 2019

Using temperatures from Jan. to Aug. to evaluate all of 2019 wtf?

Pure Bullshit

Time to peer review that claim.

First question. WTF is "normal" and how is it determined.

Environment Canada says...

Canadian Climate Normals 1961-1990

1.0 Introduction

"Normals" is the term commonly used for values of climatic elements averaged over a
fixed, standard period of years. In the 1930's, the 30-year period from 1901 to 1930 was selected as the first international standard period. The selection of this number of years

was somewhat arbitrary, however it was considered sufficiently long to eliminate year- to-year variations. In 1960 it was agreed that countries should continue to use 30-year periods, but that normals should be updated every decade rather than every 30 years, beginning with the period 1931 to 1960.



10 year average and as you noted Jan-Aug? Are they serious?

F-cking fake news. This shit has to stop.

More from the fake news article...


The dire report, released ahead of the UN Climate Change Conference COP25 in Madrid, found that exceptional global heat driven by greenhouse gas emissions mean this decade will most likely go down as the warmest on record.

Where does that "record" come from?

The Record consists of the 1951-1980 data set as noted by NASA:

Global temperature records start around 1880 because observations did not sufficiently cover enough of the planet prior to that time. The period of 1951-1980 was chosen largely because the U.S. National Weather Service uses a three-decade period to define “normal” or average temperature. The GISS temperature analysis effort began around 1980, so the most recent 30 years was 1951-1980. It is also a period when many of today’s adults grew up, so it is a common reference that many people can remember.

This article is all over the deception map.

More from T_M's link...

It also stated that 2019 will be the second or third warmest year, with the global average temperature during January through October roughly 1.1 C above the pre-industrial era.

Whitewood said Canada was 0.8 C above average from January to August, and that the country is on track to be the 21st warmest since 1948, the year that the agency began tracking temperatures for the whole country and not just the southern half.


“It is above normal, not record-setting, but part of a warming trend across the country… the temperature is increasing over the years,” he said in an interview Friday.


Hold the flippin phone! 1.1C above pre-industrial era? Didn't NASA say "Global temperature records start around 1880 because observations did not sufficiently cover enough of the planet prior to that time"?

I never know "ever" was only 71 years.

Does this mean I can razz my mother over being born 20 years before time began?

21st warmest out of 71 years. Think about that.

Show us those stats. A bar graph will do.

That data set is only being used to produce that one map on their website.

The hottest year on record statement is made using all available data.

Science is not your thing.

No. It's the standard. Wake up Mr Woke.
