ITS NOT A OR BMia looked at a graph showing average global temperatures. She noticed that the average temperatures have risen abruptly over the past several decades. This indicates that global warming is occurring at a fast rate. What additional pieces of evidence do scientists use to support the idea that global warming is happening? the amount of greenhouse gases leaving the atmosphere and increases in amounts of sea ice

the greenhouse effect and reductions in sea levels

greenhouse gas concentrations, decreases in amounts of sea ice, and increases in sea levels

ocean temperature changes, greenhouse gases concentrations, and harmful emissions reductions
