WILMINGTON, Del. (AP) - Scientists say that climate change is prolonging allergy season and the suffering that goes along with it.

The News Journal in Wilmington, Delaware, reported Thursday that local doctors are seeing more people who are suffering from allergies and that they are suffering for longer periods of time.

Scientists say that deforestation and the burning of fossil fuels are sending more greenhouse gases like carbon dioxide into the atmosphere.

Those gases in turn warm the planet and extend allergy season. Some studies have even found additional carbon dioxide may even cause some plants to produce even more pollen.

Local historical data shows that Delaware appears to be getting warmer.

Delaware State Climatologist Daniel Leathers said that has meant a longer span between frosts when plants can bloom and grow.
