Yes, volcanoes can affect weather and the Earth's climate. Following the eruption of Mount Pinatubo in the Philippines, cooler than normal temperatures were recorded worldwide and brilliant sunsets and sunrises were attributed to this eruption that sent fine ash and gases high into the stratosphere, forming a large volcanic cloud that How many active volcanoes are there on Earth? There are about 1, potentially active volcanoes worldwide, aside from the continuous belts of volcanoes on the ocean floor at spreading centers like the Mid-Atlantic Ridge.
About of those 1, volcanoes have erupted in historical time. Many of those are located along the Pacific Rim in what is known as the " Ring of Fire. Can an eruption at one volcano trigger an eruption at another nearby volcano?

There are a few historic examples of simultaneous eruptions from volcanoes or vents located within about 10 km of each other, but it's very difficult to determine whether one eruption caused the other.
