Although Zelon's hypothesis is a bit more in depth and different, there have been peer-reviewed research papers which have linked geomagnetic field variations, or geomagnetic jerks aka changes in Earth's magnetic field, with cooling events/climate change in the past.
Climate determinism or Geomagnetic determinism?
Possible impact of the Earth's magnetic field on the history of ancient civilizations
The Mayans: Climate determinism or geomagnetic determinism?
Let's simplify this shall we.
Climate scientists are unsure exactly how much impact humans have on the climate. But more are coming around to the fact that humans have SOME impact. Some think we have a bit, and some believe humans have a greater impact than we realize.
Regardless, they are not positive. So OP and anyone else really.. how do YOU know if humans are actually impacting our climate? Answer: You don't. Unless you actually believe you know more than all the scientists who actually study our climate endlessly.. (hint: you don't).
Oil companies would love for people to think there is no problem - they still have trillions to make after all. So it's hilarious to me when I hear about a clean energy "scam" agenda. If it is, I'd rather be scammed by someone producing clean energy, rather than by oil companies.

The extent to me on how much impact we have on the warming is kind of moot.
It is not to the "carbon tax" people.
Clean renewable energy can make cleaner air and sever our reliance on asshole countries for their oil.
yeah but then the S&*thole countries aspire to be a$$hole countries and have their natural resouces(fossil fuels) exploited by the man
I agree we should lessen our reliance on a$$hole countries.
Should we start with canada?
Why start with any country when the carbon crisis is supposedly a hoax?

I don't forget the Sun, but I know that its output has not changed enough to account for the rise in temperatures.
Is the solar system entering a nearby interstellar cloud

Observational arguments in favor of such a cloud are presented, and implications of the presence of a nearby cloud are discussed, including possible changes in terrestrial climate. It is suggested that the postulated interstellar cloud should encounter the solar system at some unspecified time in the near future and might have a drastic influence on terrestrial climate in the next 10,000 years.
ESA sees stardust storms heading for Solar System
Date Released: Monday, August 18, 2003
Source: Artemis Society
Until ten years ago, most astronomers did not believe stardust could enter our Solar System. Then ESA's Ulysses spaceprobe discovered minute stardust particles leaking through the Sun's magnetic shield, into the realm of Earth and the other planets. Now, the same spaceprobe has shown that a flood of dusty particles is heading our way.
What is surprising in this new Ulysses discovery is that the amount of stardust has continued to increase even after the solar activity calmed down and the magnetic field resumed its ordered shape in 2001.
Scientists believe that this is due to the way in which the polarity changed during solar maximum. Instead of reversing completely, flipping north to south, the Sun's magnetic poles have only rotated at halfway and are now more or less lying sideways along the Sun's equator. This weaker configuration of the magnetic shield is letting in two to three times more stardust than at the end of the 1990s. Moreover, this influx could increase by as much as ten times until the end of the current solar cycle in 2012.
Like a wounded Starship Enterprise, our solar system's natural shields are faltering, letting in a flood of cosmic rays. The sun's recent listlessness is resulting in record-high radiation levels that pose a hazard to both human and robotic space missions.
Galactic cosmic rays are speeding charged particles that include protons and heavier atomic nuclei. They come from outside the solar system, though their exact sources are still being debated.
Magnetic Field Weakening in Stages, Old Ships' Logs Suggest
for National Geographic News
May 11, 2006
Earth's magnetic field is weakening in staggered steps, a new analysis of centuries-old ships logs suggests.
The finding could help scientists better understand the way Earth's magnetic poles reverse.
The planet's magnetic field flips—north becomes south and vice versa—on average every 300,000 years. However, the actual time between reversals varies widely.
The field last flipped about 800,000 years ago, according to the geologic record.
Since 1840, when accurate measures of the intensity were first made, the field strength has declined by about 5 percent per century.
Ribbon at edge of our solar system: Will the Sun enter a million-degree cloud of interstellar gas?
May 24, 2010
Space Research Centre, Polish Academy of Sciences
Is the Sun going to enter a million-degree galactic cloud of interstellar gas soon? A U.S.-Polish team of scientists suggests that the ribbon of enhanced emissions of energetic neutral atoms, discovered last year by the NASA Small Explorer satellite IBEX, could be explained by a geometric effect due to the approach of the Sun to the boundary between the Local Cloud of interstellar gas and another cloud of a very hot gas called the Local Bubble. If this hypothesis is correct, IBEX is catching matter from a hot neighboring interstellar cloud, which the Sun might enter in a hundred years.
The Northern lights, it seems, have moved further south and have been visible from countries including Germany and Denmark. So what exactly is causing this spectacle? And how long will it last?
