A
Alternative technologies are not yet available.
B
Alternative technologies consume more fossil fuels.
C
Alternative technologies can be more expensive than traditional technologies.
D
Alternative technologies have been proven not to work very well.
Explanation: 

Detailed explanation-1: -What is one challenge that comes with using alternative technologies to reduce greenhouse gas emissions? Alternative technologies are not yet available. Alternative technologies consume more fossil fuels. Alternative technologies can be more expensive than traditional technologies.

Detailed explanation-2: -The wind turbines reduce carbon dioxide emissions by providing an energy source that does not burn fossil fuels, while artificial trees, a new emerging technology, would remove carbon dioxide already in the atmosphere.

Detailed explanation-3: -Climate technologies that help us reduce greenhouse gas emissions include renewable energies such as wind energy, solar power and hydropower. To adapt to the adverse effects of climate change, we use climate technologies such as drought-resistant crops, early warning systems and sea walls.
