I'm writing about a planet that is harsh but livable. This planet is covered with mountains and active volcanoes. Far more volcanoes than what exists on Earth. It is more like Venus but is much further away from the Sun and has a faster rotation speed. This planet has a very hot core and there is a volcanic eruption somewhere on the Earth-sized planet every day.
Assuming the planet has many characteristic similar to Earth, just with more volcanoes, how would the climate be like? On one hand, a hot core and all of the magma and gasses pouring out should heat up the planet. On the other hand, the volcanic eruptions would block sunlight from reaching the planet's surface which would cool down the planet. As a result, I'm not sure if the planet would be overall hotter or cooler than Earth assuming that it orbits a yellow dwarf star 1 astronomical unit away. I'm assuming it would be hot near volcanoes and cold elsewhere.
