From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum.

Climate change is putting people at greater risk from deadly carcinogens while threatening their access to cancer treatment, according to a new study by public health experts.

Extreme weather events like hurricanes and wildfires are increasing in intensity and frequency due to climate change and in turn, release carcinogens into the atmosphere.

Hurricane Harvey battered Louisiana and Texas in 2017 with devastating impacts felt along the Gulf Coast and in the city of Houston. The category-4 storm inundated chemical plants, oil refineries, and Superfund sites that contained vast amounts of carcinogens that were released into the Houston community, the researchers found.

In 2018, an investigation by the Associated Press and Houston Chronicle found more than 100 toxic releases into surrounding communities related to Hurricane Harvey, on land, in water and in the air.

The increase of patients' exposure to carcinogens was compounded by the fact that the hurricane conditions made it difficult for patients to seek preventative care and treatment while also threatening the lab and clinical infrastructure that supports cancer care.

The study was published today in CA: A Cancer Journal for Clinicians by researchers from the American Cancer Society and Harvard University. Cancer is the second-leading cause of death for Americans.

Wildfires are another risk. Global warming has led to longer wildfire seasons in the US that have spread over greater areas. Widespread burning releases vast amounts of air pollutants that are known to cause cancer, the study notes.

Lung cancer is associated with long-term exposure to particle pollution and wood-fire smoke but few studies have been conducted. It’s unclear how short-term exposure to such smoke will affect people, AP reported.​

Tackling climate change will have both environmental and health benefits. Reducing greenhouse gas emissions will not only be good for the planet but will reduce air pollutants emitted from combustion processes that are harmful to health, the study noted.

Another proposal for tackling cancer is diet. The Mayo Clinic estimates that around a third of cancer cases could be prevented by switching from animal sources to a plant-based diet.

The agricultural sector is the source of one-third of greenhouse gas emissions with cattle as the main agricultural source of greenhouse gases worldwide, according to UC Davis.

The authors of the new study wrote: "While some may view these issues as beyond the scope of responsibility of the nation's cancer treatment facilities, one need look no further than their mission statements, all of which speak to eradicating cancer.

"Climate change and continued reliance on fossil fuels push that noble goal further from reach.

"However, if all those whose life work is to care for those with cancer made clear to the communities they serve that actions to combat climate change and lessen our use of fossil fuels could prevent cancers and improve cancer outcomes, we might see actions that address climate change flourish, and the attainment of our missions to reduce suffering from cancer grow nearer."​
