There are a handful of things -- around energy efficiency, renewable energy, reducing deforestation -- a handful of things that the world could do and we could help turn the corner by 2020 and get on track to reduce emissions enough to keep the climate safe.
Renewable energy sources like solar, wind and hydropower create 8.5 percent of the worlds energy. Nuclear power creates about 11.5 percent.
Mr. Koehane says the report shows some countries are not making the change from fossil fuels to cleaner energy.
When you look at the stats and the data in the report, it shows, for example, that coal has been growing faster than other sources. So we need to reverse that trend and we do need to rapidly ramp up the sources of renewable power, the share of renewable power.
The report says there will be a greater cost to public health and the environment if there continue to be delays in reducing emissions.
Mr. Koehane says voters must tell their leaders that reducing climate change is important to them. He says we have the knowledge and the technology to make changes. He is hopeful about the possibility of change.
If we do get that political will and if we can push in that direction, that we have the technologies to get started on this problem. We just need everybody to pitch in.
The report says there is still time for the international community to take actions to reduce climate change caused by human activity.
