Are meteor showers threatening? I know all of them burn up in our atmosphere but are there any big enough to harm us in space debris?

Eventually, over time, some object will land somewhere and cause harm, but most of the stuff is basically only sand-size or thereabouts at most, so is not a source of danger. Burns up from friction when in the air.
To my knowledge, there is only one person in documented history that was struck by a meteor. Some lady in Alabama or someplace like that had a meteor crash through the roof of her house and hit her while she was sitting in her living room.
So, sure, it is possible that something from up there can get through and cause problems (like the monster rock that supposedly wiped out the dinosaurs) but it is a very, very rare thing. Most don't make it to earth, and the ones that do, don't hit anything "important" like people and cities. Only a few ever get big enough to even make a crater, which apparently happens every few thousand years or at the very least. Random enough that it is impossible to predict accurately.
Probably more at risk from the falling leftovers of all our satellites and spacecraft, actually. Some of those things tend to be big enough that some can make it to ground, although most does not, and even when it does, it mostly lands in the ocean, which covers about 2/3 of the surface of the earth.
You are far more likely to be hit by a car walking around town. And you don't really worry about that much, I bet.

not if you can escape to greenland in time.

Meteor showers are a triumph of hope over reality. They are nothing like a firework display with the sky aglow with falling sparks. A meteor shower is where you stand out in the dark looking up at the night sky, and if you are lucky you see one or two meteors every few minutes.
Most harm comes from people either tripping over things in the dark, or straining a neck muscle while they are at it.

About 500 meteors make it to the Earth's surface each year.
One could harm someone if it hit their house or car, but so far there are only 2 recorded cases in the entire world in the entire written history of someone being hurt by a meteor.

Everything smaller than about 10 meters across burns up in the atmosphere.
Most of the meteors in meteor showers are a hundred times smaller in diameter and a million times smaller in mass.
Every year or two there is a bolide that is bigger than 10 meters somewhere on Earth, usually falling into the ocean.

Components of meteor showers are invariably small (<5 cm.) and never survive to reach the surface of Earth. Meteorites, objects which have reached the surface, are larger and travel as individuals, not part of showers.
There have been a few cases of fatalities, the most recent was the Tunguska Impact of 1908, in which a man 30 kilometers away was knocked off his porch and died days later of injuries. One in the early 18th century in Arabia is believed to have killed a couple people, and Latvia claims one from prehistory killed people in what is now their country.

There *can* be larger chunks that are big enough that they don't completely burn up in the atmosphere; we find them all the time. Usually, they're small pieces of rock or metal that have fallen randomly, but they can be quite large.
To my knowledge, only 1 person in history was injured from a meteorite; a woman was struck by the rock after it crashed through her roof in 1954. https://en.wikipedia.org/wiki/Sylacauga_(meteorite...
The really large ones - those that cause damage around them, leaving craters and such - are pretty rare. It's *possible*... but not very probable.

Meteor showers are remnants of what comes out of comets (the tail) when and if they intersect Earth's orbit path. These particles remain there for a long period of time orbiting the sun too just like the mother comet. And they are usually more bright and numerous when the mother comet has passed Earth's orbit nor long before.
No they will not harm us because they are as small as grains and will fully disintegrate before reaching earth's surface.
