The record-setting Canadian wildfires in 2023 were caused mainly by lightning igniting forests that were unusually hot and dry, in part due to climate change. But the recent conviction of a Quebec man led to false claims on social media that the majority of the fires were the result of arson.
Q: Are electric cars really better for the environment than gasoline-powered cars over their lifetimes?
A: Yes. Electric vehicles typically release fewer greenhouse gas emissions than internal combustion engine vehicles during their life cycles, even after accounting for the increased energy required to make their batteries. And their carbon footprints are expected to get smaller in the near future.
The Earth is warming at the fastest rate seen in the last 10,000 years, according to NASA, and the consensus among climate scientists is that human activity is causing the change. But a meme on social media tries to undermine the reality of climate change by misrepresenting the views and media coverage of a climatologist popular among those who believe climate change is a “hoax.”
Greta Thunberg recalled in a 2022 BBC interview how she began her environmental activism. But a recent video shared on social media deceptively alters the audio from that interview, making it appear that Thunberg called for the use of eco-friendly military weapons and “vegan grenades.” The altered video originated on a site that labeled it as satire.
It’s not known what sparked the wildfires in Maui, although some evidence points to downed power lines. The conditions were ripe for fire, as large amounts of invasive grasses were dry due to drought and high winds helped to rapidly spread flames. Bogus posts on social media, however, are baselessly claiming the fires were intentionally set.
