As far as we know, infrared radiation is not harmful to humans. However, you must never leave a new born baby or an animal in a car on a sunny day. The infrared light will get trapped in the car and the baby or animal has a very high risk of dying. This is the same thing that happens to our atmosphere, causing global warming.
its trapped by radiation. your welcome.
The danger is, if the infrared is trapped by atmospheric gases it can cause greenhouse effect.
Aluminum foil is a conductor of heat energy. However, it does reflect radiation from heat sources, so it can reduce heat transfer through radiation. When aluminum foil is wrapped around something, pockets of air can be trapped. Trapped air is an excellent insulator against conduction and convection. However, if you want to prevent something like a can of soda from getting warm in your lunchbox, a wool sock will be a better insulator. Even paper toweling is better at insulating than aluminum foil when light is not shining.
Solar radiation that is not reflected is absorbed by clouds, the atmosphere and the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%Source: (NASA)

Yes, some of it can. Infrared radiation is trapped by greenhouse gases, but not all of it is trapped. These gases only trap radiation in very specific parts of the electromagnetic spectrum, so there are "windows" where it can escape.
infrared
That would be infrared rays, this is due to the wavelength.
terestrial
Greenhouse gasses such as carbon dioxide, water vapour and methane act to slow down the escape of infrared radiation from the atmosphere. It is this trapped radiation that warms up the planet.

green house effect
more heat can be trapped in the atmosphere...
Trapping infrared radiation (rising from the surface of the earth) keeps the atmosphere warm enough for life. This has been happening for hundreds of millions of years.However, when too much heat is trapped, as is happening now, then the atmosphere starts getting warmer. This is called global warming. This is a bad thing!
