Is it 'geoengineering' or 'hacking the climate?' A raging dispute among climate scientists is breaking into the open. Could they slow global warming by injecting aerosols into the atmosphere to reflect sunlight, or are the unintended consequences potentially so dangerous that even experimentation should be prohibited? The very idea was beyond the pale at the time of the Paris Agreement, but now it's gaining some traction. Opponents say it's beyond reckless. Would trying to resolve one problem create others that could get out of control?
Will the Senate write a healthcare bill in secret? While Democrats and Republicans argue White House relations with Russia, another question is being decided behind closed doors: who gets help buying health insurance and who doesn't? We hear how the pros and cons are being shrouded in secrecy.
Is the threat from Russia missing from the Russia meddling probe? There's much being made about the Trump administration's possible ties with Russia. But the bottom line is Russia's effort to influence American democracy. Do the President and his aides care enough to take action before voters go back to the polls?
The longest US war: Will Trump send more troops to Afghanistan? The Trump White House is divided over the Pentagon's request for more troops in Afghanistan—where the US has been fighting for the past 16 years. Is there a formula -- either for "victory" or a political settlement? Is there an end in sight for America's longest war?
