Why climate change is so hard to tackle: The global problem

Democratic presidential hopefuls are calling for aggressive action to reduce heat-trapping emissions, while nations are facing pressure to ramp up commitments ahead of a major United Nations summit next month.

The big picture: Despite that fervor, progress on climate change remains elusive. We have cultivated a deep dependence on fossil fuels that have been driving Earth’s temperature up for more than a century, creating a problem whose mostly negative impacts are unfolding over more centuries.

As wind and solar energy grow, so do their challenges

Costs for wind and solar electricity have plummeted in the U.S. and around the world, driving incredible growth in these cleaner sources of energy and helping combat climate change.

But, but, but: The costs associated with the variability of wind and solar — it’s not always windy or sunny — are growing as states, progressive politicians and corporations push for rapid increases in these resources to levels much greater than what we have today.

The energy and climate change puzzle

People often ask me how I decide what to cover in this noisy and disparate energy and climate change beat. My answer: I stay focused on the puzzle.

The big picture: I look at the various factors that go into reducing greenhouse gases in a world that depends upon the energy resources that emit them. That is a simple deduction of what is a complex dynamic. Like puzzle pieces, these numerous factors work in tandem, not in isolation.
