SUMMARY: Dust from asteroids entering our atmosphere could affect the weather more than scientists previously believed, according to a new study published this week in the journal Nature. An international team of researchers have studied the dust trail of an asteroid that burned up as it descended through the atmosphere above Antarctica. The 1,000 tonne asteroid formed a cloud of micron-sized particles large enough to influence the local weather in Antarctica.

I have always believed that space weather and dust as well as other phenomena will effect our weather/climate here on Earth. It just stands to reason that if dust happens to blow into the area btween the Eath and the Sun, our weather here will be affected. Less sunlight, cooler temps, more benign weather. (To a point) Also solar winds triggered by solar activity should effect our climate here by changing the amount of heat radiation that strikes the Earth's atmosphere and surface. Since our weather is caused by however much heat is generated by solar radiation at the time, any dust, debris, etc. Should affect how comfortable we are.

Space is much larger than our little blue planet and the protective atmoshpere is relatively thin. B)
