Do volcanoes impact global warming?

It all depends. 
During an eruption there is a mixture of gases and different particles that enter the atmosphere. These include ash and sulphur dioxide. The substances that they cause help to reflect the sunlight away from the earth.
Other types of gases and mixtures such as C02 can cause warming. This can add to the greenhouse effect.
