Climate Challenges Don't See Borders As NASA Pic Shows Smog-Covered Lahore, Delhi

It shows location pins for Lahore in Pakistan's Punjab and New Delhi, with both cities under huge cloud of grey smog. Lahore - a city of 14 million people stuffed with factories on the border with India - regularly ranks among the world's most polluted cities, but it has hit record levels this month.
