I have about 7000 hours in the CR2 now and can say with confidence that an awful lot of windshear events are pilot induced. Guys chase airspeed with throttle too aggressively and end up fast then a gust kills the speed and they overreact and the speed climbs like crazy and then they pull it back to idle. Or something like that.
Many of these events can be dealt with by holding a bit more speed to begin with and bring it back slowly closer to the ground.
I'm not saying real windshear can't happen but in my experience it is often accentuated by overcorrection with the throttles.

If I get windshear I'm mashing those throttles into the EICAS. What is this BS "graduated" approach to using power in a windshear. You don't pay for the engine hours and stress put on them from max power, you are paid to keep people alive.
You have no way knowing how bad it is or how bad it can get. You might just be encountering the edge of a stronger microburst event that could get really bad really fast. I'd rather at that point have as much speed and altitude as I can get.

Never had a windshear warning in the CRJ-200, but did have a couple of windshear cautions going into DCA and PHL on particularly breezy winter/spring days.
Had a couple of windshear cautions in the CJ2+ too, but again, no warnings...and all of them were +/-15kts.
If I ever get an honest-to-goodness warning, its escape maneuver until I see 4000fpm+ climb and let maintenance inspect the engines when we land.
As saab2000 said, carry a little extra speed and you don't have to go sawing on the power levers, making a crappy situation worse.

In my nearly 9 years now in the CRJ-200 I have never seen a red windshear warning that was legit. There were a couple of false alarms which were quite clearly not wind shear. Calm winds and blue skies in ILM once and another with about 10 knots out of the NW. False alarms. No panic. No shoving the levers to the stops. No drama.
People need to take the possibility of wind shear seriously but gusty winds is not a reason to panic. I landed at JFK once with gusts to 50 knots and there was no real trouble.
If you're landing underneath a thunderstorm it could be different but we need to be asking ourselves if that is a wise move to begin with.
