(This is only very brief)
Environmental issues are created by the earth as a whole which includes all the countries within it therefore making environmental issues global issues. No country alone has caused global warming.

Answer:
It would look like an uplift or dome because the laccolith below is a lens-shaped mass of magma that pushes the rock above it upward.
Explanation:
The laccolith is formed by volcanic activity. Not all of the magma is contracted in the volcano and comes out form it or solidifies in it. Some of the magma actually moves below ground in the surrounding area, using the cracks as pathways. When this magma cools off deep underground it creates intrusions.
One of those intrusions is the laccolith. The laccolith can be described as having a lens-shape, or that it looks like a mushroom. The laccolith is in intrusion that pushes the crust upwards, so the surface above it uplifts or looks like a dome that sticks out in its surroundings.
The laccolith may come out eventually on the surface because of the weathering and erosion, but for that to happen usually millions of years are needed.
