A cooler Berlin means higher emissions....

It's ironic - as things cool, emissions go up....

German coal consumption jumped 3.5 percent in January as colder weather increased demand, boosting emissions of greenhouse gases in Europe's biggest economy, government statistics show.

Electricity generated by burning hard coal and lignite climbed to 24.35 terawatt-hours from 23.52 terawatt-hours in the same month a year earlier, according to the state statistics office, whose January data is the latest available.

Coal burning expanded to meet higher demand for heating as temperatures in Berlin fell an average 2.3 degrees Celsius below those a year earlier.
