On global warming, data for all

WASHINGTON — The Obama administration hopes to fight global warming with the geeky power of numbers, maps, and even gaming-type simulations.

Officials figure the more you know about climate change, the more likely you will do something.

‘‘People need to understand what is happening and what is likely to happen,’’ White House science adviser John Holdren said.

The White House on Wednesday announced an initiative to give companies and local governments better access to public climate data. The idea is that with that localized data they can help the public understand the risks they face, especially in coastal areas where flooding is a big issue.

The government also is working with Google, Microsoft, Intel, and others to come up with tools to make communities more resilient in dealing with floods, heat waves, and droughts. They include computer simulations and new apps on disaster risk.

‘‘The more people that have information, the harder it is for a few to block action’’ on climate change, Holdren said.
