New research suggests that air travel in tropics increases global warming more than a flight in temperate latitudes.
As well as producing carbon dioxide and contrails, planes also produce nitrogen oxide, which triggers both the creation of the warming gas ozone, and the destruction of another greenhouse gas, methane, according to the study.
Cold Truth in Antarctica: Penguins Freeze to Death
Global warming is leading to unusual epic rains in Antarctica, which is in turn causing the region's penguins to freeze to death.

But the brighter sunlight in the tropics is very efficient at converting nitrogen oxide to ozone - in fact it creates ozone five times faster than in the air of mid-latitudes, according to Shine's calculations.
Whereas methane destruction only increases marginally, Shine added.
Research Finds Ozone Being Destroyed Over Tropical Atlantic Ocean
Scientists have discovered that large amounts of ozone - around 50% more than predicted by the world's state-of-the-art climate models - are being destroyed in the lower atmosphere

The research raises the question of whether future attempts to control aircraft emissions should consider extra penalties for flights in tropical countries where air travel is booming. India, for instance, has the fastest growing airline fleet in the world.

World Should Focus on Short-term Goals to Reduce Carbon Emissions, Says Study
A new study has called for stronger short-term goals to reduce carbon emissions, as long-term climate change policy is likely to reverse the tide of climate change very slowly.
