(NaturalNews) A leading climate scientist from the U.K. had a Freudian slip moment recently when he admitted, perhaps without realizing it, that climate geoengineering in the form of "chemtrails" is not only not some wild conspiracy theory, but is an actual thing happening all around the world right now.

Professor Tim Lenton, chair of Climate Change/Earth Systems Science at the University of Exeter in the U.K., participated in a question and answer session at the Our Common Future Under Climate Change conference in Paris back in July, where he agreed to answer a compelling question about weather modification and its effects on our planet.

Olga Raffa from Chemtrails Project U.K. asked Prof. Lenton why "ongoing" geoengineering programs are taking place without any research as to their outcomes. She also asked about how the use of "aerosols" is justified when the aluminum, barium and other chemicals they contain is a known killer of bees.

"I represent a large group of people who are wondering why programs such as weather modification and ongoing geoengineering programs throughout the world have not been taken into consideration with a lot of the research done," Raffa asked, pointing to the ongoing climate change debate and its lack of attention on geoengineering.

"And we notice, on a daily basis, that our environment is being tipped through the aerosols being dumped into the atmosphere blocking our sun. And there seems to be a lot of aluminum in the environment – within the bees now have aluminum, and it's destroying their, well, there's a bee collapse obviously with the insects and the biodiversity."

Raffa also brought up electromagnetic radiation (EMF), HAARP (the High Frequency Active Auroral Research Program), covert military programs and other hard-hitting topics that many other climate scientists have chosen to ignore – but not Prof. Lenton.
