Massive storms, flooding, extreme heat, droughts, air pollution, increased rates of disease, changes to our food and water… global warming, and the changes to climate that come with it, are increasing human health risks. Our physical and mental health both stand to suffer, and some populations are more vulnerable than others. What are the specific health issues, what can we do to address them, and most importantly – is there any hope?
We hope to answer these questions and more in a handful of episodes on Climate Change and Health. This year, we’re going to be taking a look at how Climate Change can impact health.

Climate change is not affecting my health
Propaganda. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.
Propaganda. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.
Propaganda. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance.
Propaganda. Heatwaves were much more severe in the 1930s.
More climate propaganda. As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found:
‘The number of significant trends was about the number expected due to chance alone.’
‘Changes in the frequency of major floods are dominated by multidecadal variability.’
‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’
‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’
Lies and propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time.
For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires.
Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data).
Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus).
There is no climate crisis.
Propaganda. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017.
Propaganda. Methane (CH4) is only 0.00019% (1.9 parts per million) of the atmosphere. Both of its narrow absorption bands occur at wavelengths where H2O is already absorbing substantially. Hence, any radiation that CH4 might absorb has already been absorbed by H2O. With the concentration of water vapour in the atmosphere being between 1,000 and 20,000 times greater than CH4, the effects of CH4 are completely masked by H2O.
We’ve had solar panels on our roof for several years.
May the Anthroprocene epoch make the Permian-Triassic extinction event seem like a minor footnote in the pages of Earth's history. Here's to making scenario SSP5-8.5 of the IPCC assessment a reality.
The world is at 1.1 Deg C and the IPPC say it could be 1.5 by 2030. Its already getting bad at 1.1 deg.
While the significant, sometimes cataclysmic, impacts and consequences of climate change are frequently mentioned during any discussion of the topic, i.e. rising sea levels swallowing coastal towns, methane gases obliterating our ozone layer, I find it refreshing to come across a video that relays the day-to-day daily impacts that these changes have on all of us, some of us with even greater significance. This is not to diminish the very real threat of long-term climate impacts, but that a degrading and detrimental environment to the human ecosystem can absolutely hasten these consequences! That aside, the implications of climate change already have very real effects on some of the most common health issues we face as a society. Respiratory syndromes across the board, with specific emphasis on conditions such as asthma and other constrictive airway diseases, can be exponentially worsened in populations that are subject to daily air pollutants. With an ever increasing global temperature, air pollutants tend to take longer to dissipitate and the vicious cycle continues. And this is just one example of very common place health concerns being affected by climate change. The less that is done to combat it, the more likely that moderately controlled health issues may become ever more pervasive.
Dr. Aaron Carroll talks about specific health issues impacted by climate change. The biggest worry is “drastic, immediate impacts on health. And we’re worried about them happening more often.” This touches on the ethics principle of justice seeing how more health crisis will lead to thinning out an already over-worked healthcare system. The justice principle is about providing fair and equitable care to patients. Tying this into climate change means not only worrying about patients impacted by extreme weather events, but also considering the rise of asthma and allergy attacks as “increases in temperature cause increases in air pollutants and allergens”. Other health concerns are the rise in infectious diseases as ecosystems are impacted by climate change. Access to clean water and food are vital to maintaining good nutrition but are hard to come by in resource-limited areas. Dr. Carroll also brings up “events like disease, severe weather, and limited access to food and water generally affect more than physical health – there are terrible mental health consequences as well”. Specifically, a positive correlation between climate change and anxiety due to the unknown future. While I agree with the points made about needing climate action to not only prevent further disparities in healthcare service, I wonder if these changes needed to be made already for it to be effective or is it already too late for any meaningful reversal climate change effects. Another discussion point utilizing justice is where should these programs be implemented first (in an area where the program will do the best or the area that needs it the most or an area that will see a modicum of success while still allowing for revisions). Discussions revolving around climate change and future healthcare policies need to take into consideration the justice ethics of their decisions to not worsen the growing socio-economical divide seen in healthcare.
This individual cares about our species but has not addressed that the economic mode: market capitalism, is indeed the actual problem. It should be understood by individuals that systems change is a transition we can no longer keep avoiding. If effective policy and legislation pushed by "moral and caring politicians" were enough then why are countries failing to meet the Paris Agreement, failing to reduce dependency on hydrocarbons. Hence increased investment in hydrocarbon, and its applications. Hence why we as a civilisation are on track for 1.5 degrees of warming AND MORE HORROR. Reduction in hydrocarbon use and a transition to cheaper renewable energy systems, and increased automation and by that abundance, would simply reduce the need for these false positions: monarchs, politician, and all businessmen, and high risk labour, and reduce the work a day week. Something our dear oligarchs are afraid of. Loss of power.
It should be known that class stratification and the resulting divide of the "have and have nots" produces unequal income, increased conflict, and produces all manner of epidemiological problems by country. We the people must actively protest for out systems change, not in systems change. The aristocratic and technocratic class will not give up their reward feedback loop, and will not reduce the conditional reinforcers that reward their operation and position. Therefore by default this video isn't for those who can acquire enough income, and agency to improve their worth to exist because our system makes people sick. They cannot reinvigorate their physical and mental health.
We have to be able to challenge the validity of the systems we live, and whether its producing viable outcomes.

We can take the YouTube video on its merits. This individual clearly cares but his suggestions on who or how some help or change occurs are for an audience who have the income and agency, and is in systems ideas, which at best produce patch work and catharsis. The systems demographic, by default, is for those who have the money to improve. He can only suggest some ideas, or ways to help but you cannot do that without money. Therefore the 3.4 billion members of humanity who struggle to meet their basic needs will never be able to take this advice. The kind of change required must be at the system level, and by improvement I mean transition into a more viable system.
Capitalist corporations are causing the 6th mass extinction and the rich elites think they're gonna survive it, true insanity
And Now for Something Completely Different. – Monty Python
Stoking fear by telling lies. Hmmmmm. Not good.
Dr. Carroll does a good job of highlighting some of the major effects climate change is already having on health. There are definitely more cases of direct effects of increased temperatures – just look at the heatwaves from summer 2022, which broke heat records and resulted in thousands of deaths. But there are so many effects down the line that are potentially even more dangerous. Mosquitos have increased rates of reproduction with every degree that the earth increases, and they spread further than ever before. Air pollution causes millions of deaths annually. The healthcare system is going to have a difficult time keeping up with all of these effects, just due to sheer volume. It’s going to be more difficult for healthcare workers to maintain ethical justice. Medical justice is the fair and equitable distribution of health resources. As Dr. Carroll mentioned, there are already many people without the means to compensate for the complications arising due to climate change. The systems in place currently violate this ethical principle as low resource countries are hit harder by climate disasters. It is the duty of healthcare professionals to treat everyone fairly regardless of their background or ability to pay, but as resources dwindle with climate change, how can fair distribution of care be maintained? This is something that we have to address as these issues only worsen.
Aerosols from jets spraying the atmosphere from top to bottom , should be your biggest health concern. Geo Engineering is real and ongoing , do some research, and stop listening to these propaganda videos about the causes.
Geo Engineering and Weather Modification programs are the main cause of " Climate Change"
It is the Big Elephant in the sky that they refuse to say they have been doing for decades ! Blaming climate change on the public is an absolute lie ! Geo Engineering has been deliberately used to cause drought and floods. These weather extremes cement the term "Climate Change"
Just another propaganda video here.
There is no climate change
3:48 I love that dress/top, what do you call an item of clothing like that?
Don't believe any of these government paid scientists say
And no mention of the Ohio train derailment. Hypocrites.
Not one mention about the Ohio chemical spill…unreal
Thank you for rising awareness about this!
There has been no increase in tornadoes, hurricanes, floods, droughts, or forest fires. They have lied to you, and this video lies to you. Wake up….. Open the door, walk outside and breathe deep, smile, and then take a kid fishing.
Glad to see you discussing this issue, though I would have preferred a bit longer of a video, including more on the solutions. Also, I feel like this video is more than a bit late, one would have hoped to have seen this sort of thing after over 200 medical journals made an emergency call to action for medical professionals in September 2021.
Even this video has attracted nay sayers who can’t be convinced by the data.
Strange. Why watch a video about something you don’t believe anyway?
Sadly there are a lot of people who refuse to consider that climate change is real and we need to do something about it. They'd rather keep driving their pollution spewing cars without concern, consuming without a care – all while being told by businesses with a vested interest in not being help accountable for the harm they're causing to the environment.
