Jupiter becomes a star, how long have we left? (2010)

"Your children will be born in a world of two suns. They will never know a sky without them. You can tell them that you remember when there was a pitch black sky with no bright star, and people feared the night."

Except, I am very much afraid Christopher's children will never be born.

So Jupiter becomes a small star. Let's assume nothing else changes in the solar system gravitationally and orbitally speaking. Jupiter is farther away from Earth than the Sun. Let's suppose its apparent luminosity (once ignited) is 15% that of the Sun; should be enough to cancel out any other star in the night sky. Fusion initiated and is maintained due to some alien technology.

Will the increased light and energy from the Jupiter-star destroy the Earth's biosphere and/or human civilization within a timescale of years?
