Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the troposphere, just below the stratosphere.
Weather is driven by density (temperature and moisture) differences between one place and another.
Space weather is the concept of changing environmental conditions in near-Earth space or the space from the Sun's atmosphere to the Earth's atmosphere. It is distinct from the concept of weather within the Earth's planetary atmosphere (troposphere and stratosphere). Space Weather is the description of changes in the ambient plasma, magnetic fields, radiation and other matter in space.
The amount of energy entering the troposphere and stratosphere from all space weather phenomena is trivial compared to the solar insolation in the visible and infra-red portions of the solar electromagnetic spectrum. However there does seem to be some linkage between the 11 year sunspot cycle and the Earth's climate.[24] For example, the Maunder minimum, a 70 year period almost devoid of sunspots, correlates to a cooling of the Earth's climate. One suggestion for the linkage between space and terrestrial weather is that changes in cosmic ray flux cause changes in the amount of cloud formation.[25] Another suggestion is that variations in the EUV flux subtlety influence existing drivers of the climate and tips the balance between states such as the El Niño/La Niña states.[26] However, a linkage between space weather and the climate has not been demonstrated conclusively.

It's based on bad science, paranoia, and ignorance.
I'm pretty sure we can blame Nick Begich for jump starting things with the book "Angels Don't Play This HAARP".

You don't know how the ionosphere affects communications yet you claim that HAARP must be up to no good.
Swell.

. By the time it reaches the ionosphere, the intensity of the HF signal is less than 3 microwatts (0.000003 watt) per cm2, thousands of times less than the Sun's natural electromagnetic radiation reaching the earth and hundreds of times less, even, than the variations in intensity of the Sun's natural ultraviolet (UV) energy which creates the ionosphere
