Researchers studying Oklahoma’s energy industry-linked earthquake surge and state regulators eager to quell the shaking have circled the wagons around a specific class of wells companies fill with wastewater and other fluid byproducts of oil and gas production.

As diplomats argue in Paris over a new global agreement to fight climate change, their work is driven by scientists' dire predictions of how unchecked warming will transform our planet decades and centuries from now.

But how can researchers be so sure of what will happen that far off?

The United States and 19 other countries on Monday promised to work toward doubling their spending over five years to support "clean energy" research.

At the same time, 28 private investors, including Microsoft's Bill Gates, Facebook's Mark Zuckerberg and Amazon's Jeff Bezos, pledged their own money to help build private businesses based on that public research.

There's a building in Mountain View, Calif., where energy-saving technologies of the future are being tried on for size.

Step inside, and the first thing you notice is the building is dead quiet: no noisy air whooshing through louvers.

That's because the building uses passive cooling instead of traditional air conditioning. Cool ground water passes through a system of small tubes running below the ceiling.

Leaders from around the world are converging on Paris for the 2015 U.N. Climate Change Conference. The two-week event is designed to allow countries the chance to come to an agreement on stifling climate change.

Below are 10 questions and answers that should better prepare you for the conference and what to expect during and after its completion.

The ground is shaking near Cushing, Okla., home to the largest commercial crude oil storage center in North America.

This little patch of prairie in northwestern Oklahoma is one of the most important places in the U.S. energy market.

Oklahoma is on track to have a record year of earthquakes — more than 5,000 have already been recorded. And those quakes appear to endanger the very industry that created them.

Nearly 150 world leaders are gathered near Paris for what is being billed as a last-chance summit to avoid catastrophic climate change.

NPR's Eleanor Beardsley reports that this is the biggest diplomatic meeting in France since 1948. She filed this report for our Newscast unit:

Delegates from nearly 200 nations are in Paris to negotiate a new agreement to curb global warming.

The first such meeting took place 18 years ago in Kyoto, Japan — a conference that produced the first international treaty aimed at slowing climate change. That attempt failed.

Scientists say the planet is closer than ever to a climate catastrophe. So this time, the climatocracy has devised a radically new approach, requesting all countries to come up with voluntary limits on greenhouse gasses. The new plan also offers poorer countries cash to help offset their costs.

Conjuring images of a dystopia, the shroud of bad air blanketing New Delhi in recent weeks has intensified global pressure on India to curb its greenhouse gas emissions.

India will arrive at the climate change summit in Paris next week as the third biggest generator of fossil fuel pollution blamed for warming the planet, after China and the U.S.

Half of India's emissions come from burning coal. A visit to the coal-rich northeastern Indian state of Jharkhand reveals how this stands to get even worse.
