Can the effects of a hotter region of the universe be mitigated on earth, at least for some time, by drastically reducing C02 emissions?
Global warming might not be directly caused by us, but if the problem slowly begins to threaten life as we know it on Earth, changing our way of life with it may make it more bearable and livable for generations.
That's my idea anyway.

Did we just learn our solar system is moving through space and the temperature varies?

In a cold corner of the world, carbon dioxide is doing something surprising. Instead of causing warming, rising CO2 levels over central Antarctica produce a net cooling effect, new research suggests.
That discovery does not undermine the fact that accumulating greenhouse gases raise temperatures elsewhere around the world (SN: 4/4/15, p. 14), the researchers say. The effect is instead a testament to the extreme and unique conditions in Antarctica’s interior.

Deep below our planet’s surface a molten jet of iron nearly as hot as the surface of the sun is picking up speed.
This stream of liquid has been discovered for the first time by telltale magnetic field readings 3000 kilometres below North America and Russia taken from space.
The vast jet stream some 420 kilometres wide has trebled in speed since 2000, and is now circulating westwards at between 40 and 45 kilometres per year deep under Siberia and heading towards beneath Europe (see diagram, below). That is three times faster than typical speeds of liquid in the outer core.
...
Why the jet is getting faster is more of a mystery. It may be related to the rotation of the inner core, which was found in 2005 to rotate a bit faster than Earth’s crust, says Xiaodong Song of the University of Illinois in Champaign, Illinois.
...
Livermore thinks the acceleration of the jet is down to push-back from magnetic fields. The flow of iron generates the magnetic field, but, he says, the magnetic field may then be affecting the flow of the iron.
...
Earth’s magnetic field seems to have been weakening, especially since around 1840, at about 5 per cent per century.
The team estimates that in total there could be about 3 million submarine volcanoes, 39,000 of which rise more than 1000 metres over the sea bed.

The 2010–2014.3 global earthquake rate increase

1. Introduction
Obvious increases in the global rate of large (M ≥ 7.0) earthquakes happened after 1992, 2010, and especially during the first quarter of 2014 (Table 1 and Figure 1). Given these high rates, along with suggestions that damaging earthquakes may be causatively linked at global distance [e.g., Gomberg and Bodin, 1994; Pollitz et al., 1998; Tzanis and Makropoulos, 2002; Bufe and Perkins, 2005; Gonzalez-Huizar et al., 2012; Pollitz et al., 2012, 2014], we investigate whether there is a significant departure from a random process underlying these rate changes. Recent studies have demonstrated that M ≥ 7.0 earthquakes (and also tsunamis) that occurred since 1900 follow a Poisson process [e.g., Michael, 2011; Geist and Parsons, 2011; Daub et al., 2012; Shearer and Stark, 2012; Parsons and Geist, 2012; Ben-Naim et al., 2013]. Here we focus on the period since 2010, which has M ≥ 7.0 rates increased by 65% and M ≥ 5.0 rates up 32% compared with the 1979 – present average. The first quarter of 2014 experienced more than double the average M ≥ 7.0 rate, enough to intrigue the news media [e.g., www.nbcnews.com...]. We extend our analysis to M ≥ 5.0 levels, as many of these lower magnitude events convey significant hazard, and global catalogs have not generally been tested down to these thresholds.
2. Methods and Data
We work with the Advanced National Seismic System (ANSS) catalog of M≥ 5.0 global earthquakes for the period between 1979 and 2014.3 with a primary focus on the recent interval between 2010 and 2014.3 that shows the highest earthquake rates (Table 1 and Figure 1). A variety of tests suggest that the catalog is complete down to magnitudes between M=4.6 and M=5.2, depending on the method used to assess it (see supporting information). We examine a range of lower magnitude thresholds above M =5.0 to account for this uncertainty.

they don't want people to panic and stop working they need people producing until the end or there would be chaos and non allied military action to secure their underground cities and "offworld" launch sites.

Our star system completes its journey through the milky way every 25920 years
In our last cycle Earth has been going through heat periods/waves and an ice age and this must be a pattern, in each of this long year cycles. If this happened to Earth so it must have happened to our companions in our solar system.
So it is repetitive, and our solar system came through this fairly unharmed each time.

Yeah. That is what I took from the OP as well. It makes complete and total sense that as we move through space and time that there would be variations in temperature and density whether our feeble instruments could record it or not. Good question.

there's more to it, than that...
as Our Galaxy rotates, our solar system, and many others, go with it like horses fixed on a merry-go-round platform
the rogue stars and comets & asteroids and molecular clouds which do not move along with the Milky-Way rotation are in vectors resulting from highly energetic events in the past (Novas ?) or else are remnants from our Galaxy cannibalizing a smaller Galaxy as happens a lot in the Cosmos
we do not know the history of the presently encountered 'hot' molecular cloud which is steadily enveloping our Solar System.... but there must be some Metaphor/Parable in religion to account this event that is 'dangerous' to all peoples/civilizations on Earth---> how could eschatology by a Divine Authority-Creator be unawares of such a catastrophe ?
#2.... why hasn't Voyagers 1 & 2 alerted Earth of this 'hot gas' approaching ? or were we notified already ?
