An extensive new study shows that climatechange can aggravate over half of known human pathogenic diseases. MedTwitter infectiousdisease
she was particularly impressed with the data visualization."It really emphasizes the magnitude of what we're dealing with. It makes you feel the weight of what they're trying to represent," she said.
On the other hand, Hauser said she would have liked"more emphasis on how the climate hazards interact with each other. It sort of made it sound like each of these climate hazards is in a vacuum — like when there's floods, and that's the problem. But there are a lot of other things…like when we have warming and surface water temperature changes, it can also change the pH of the water and the salinity of the water, and those can also impact what we see with pathogens in the water.
McKenzie explained one limitation: the study looked only at 10 keywords. So an example of a dust storm in Africa causing an increase inin the US could not be identified by this approach."This also goes back to the scale of the problem, because we have something going on in the Sahara that's impacting the East Coast of the US," he said.
Instead of looking at only one individual or group of pathogens, the study provided a much broader review of infections caused by an array of climate hazards. As McKenzie said,"No one's actually done the work previously to really just try and get a comprehensive picture of what we might be dealing with. And so that was the goal for us.
McKenzie concluded:"If we're looking at the spread of some more serious or rare diseases in areas, to me then the answer is…we need to be aggressively mitigating greenhouse gas emissions. Let's start with the source."
