Letters: Global warming isn't a hoax; it's a scientific consensus

"Scientific consensus from 97% to over 99% of climate scientists confirms that Earth is warming and that human activity—specifically burning fossil fuels—is the primary driver. Rapid temperature increases cannot be explained by natural cycles alone; and evidence shows rising temperatures, greenhouse gas accumulation and significant measurable impacts on climate."

"The United Nations Intergovernmental Panel on Climate Change concludes that human influence has unequivocally warmed the atmosphere, ocean and land, causing rapid, widespread and intensifying changes."

"California is the fourth-largest economy in the world. Every 12th person in America is a Californian. Our state is a national leader in and an international model of progressive policy, policy largely sponsored by Democrats."

A letter writer responds to claims that global warming is a hoax, citing overwhelming scientific consensus from climate scientists confirming Earth's warming and human responsibility through fossil fuel burning. The UN Intergovernmental Panel on Climate Change confirms human influence has unequivocally warmed the atmosphere, ocean, and land, causing rapid and intensifying changes. The writer supports senators who recognize climate change threats and back mitigation legislation to protect constituents. A second letter addresses California's gubernatorial race, noting the state's significant economic and political influence as a progressive leader. The writer expresses concern that California's primary system could result in two Republican candidates advancing to November despite the state having nearly twice as many registered Democrats as Republicans.
