Question

Predictions made from models used by the IPCC for future emissions show that as of 2007, which of the following has not accelerated faster than predicted?

a) Sea level rise
b) Carbon dioxide levels
c) Global temperatures
d) Glacier melting

Answer 1

As of 2007, global temperatures have not accelerated faster than predicted by the IPCC, while sea level rise, carbon dioxide levels, and d) glacier melting have exceeded earlier projections.

Step-by-step explanation:

Predictions made from models used by the Intergovernmental Panel on Climate Change (IPCC) for future emissions show that as of 2007, global temperatures had not accelerated faster than predicted. In the context of climate predictions, sea level rise, carbon dioxide levels, and glacier melting have all accelerated faster than earlier projections. Factors contributing to sea level rise include thermal expansion of the oceans due to rising temperatures and melting ice from glaciers and ice caps. Meanwhile, rapid increases in carbon dioxide emissions from the burning of fossil fuels have contributed to the greenhouse effect, exacerbating global warming. It's important to consider that while global temperatures have increased, this rise may not have exceeded IPCC predictions by 2007. However, other related phenomena such as sea level rise and melting of polar ice caps have shown faster acceleration than previously modeled. The continuation of such trends has significant implications for coastal areas, marine ecosystems, and global climate conditions.
