NASA hopes nations will work more closely together in the future on issues such as climate change, including greenhouse gas emissions, the space agency's chief, Bill Nelson, said Tuesday. Solutions to mitigate the greenhouse gas emissions that are rapidly warming the planet and driving the climate crisis already exist, but they require unprecedented change at a new scale and pace.

"This is something that nations can work together on because the information is there," Nelson said in Mexico City when asked how to address greenhouse gas emissions. "It's important that we act on it." (Stefanie Eschenbacher, more at Reuters.com)
