Throughout history humans (our species and others before us) have adapted to the most hostile environments of the plant; we have survived more severe weather pressures than the current one and we have occupied ecological niches for which we were not adapted at all. Now, in addition, we have to count on our technological capacity, which allows us, for example, to survive for months in outer space. I do not see any problem for humans. The problem is what the rest of the species will have, if the changes become too fast for them to adapt.
Specifically, what health problems? Often, there are allergies, to electric fields, dust and food components. Many health problems are local, and individual.
I understand that as a geologist you have a special perspective. Biologists are concerned that the global problem (the 1ºC temperature increase) can have different consequences according to the ecosystem. There are local effects that are added. The number of variables is huge, so the predictions are estimates. I do believe that we must act as soon as possible because if scientists are predicting these changes, the general public will act a posteriori. Skeptical postures do not help. We must begin to incorporate alternative forms of energy as soon as possible. The combustion of oil and derivatives must remain in history.
Your question is not very well written, however, I understand, the truth, I think not, you can take a review of blood and respiratory physiology, there you will find fundamentals to answer your question accurately, because there are many factors That influence the adaptation, at least, the partial pressure of oxygen, cardiac output, blood pressure, etc.
Here in Buenos Aires the weather has changed a lot since I was a little girl. It rains much more, there are more cloudy days, the change of seasons (autumn, winter, spring and summer) is less noticeable.
It should be have in mind that molecular oxygen (which allows aerobic life forms = O2) has formed in the Earth's atmosphere as a product of photosynthesis. Here there is deforestation and livestock activity (cows produce a lot of CO2) and large areas with monocultures (soy, corn, etc.). There are undoubted local effects (my English is not very good either, apologies).
Dear Maria, there is no doubt that changes in climate are occurring in many places in the world. Global warming and its impact on the climate is evidence for some time. Another thing is that we are concerned about these changes and take measures to stop them, or that certain countries, read those who have interests in the Arctic basin, prefer that the warming continue, before the opportunities that are coming with an Arctic without ice in summer.
For humans this will not be a bigger problem than moving economic activities and population to the new areas. But for many ecosystems the change can be catastrophic.
Possibly we lack some systematic studies on the subject of climate (it is not my specialty). I am a biologist. What I detect and observe is a great deterioration of the environment, pollution, a lot of rain, etc. Possibly there are multiple factors including the demographic. Of course, if there are economic possibilities, like the tunnels they do in Denmark, there will be places to take refuge in cases of chaos. We here have a very low standard of living and we are possibly much more exposed to suffer the consequences of that marvelous industrial revolution (I am a lover of Darwin's work!). But we are in a world of great inequality. Buenos Aires was once a place where people could develop more. We are very subject to an unfair trade, that is undeniable. Climate change is everyone's problem, but the amount "per capita" of CO2 emissions for which we are responsible is much less than of yours. Not to mention the harmful effect of the bombings anywhere on the planet. It's interesting and we're on track to help to solve it.
These changes have led to many environmental risks to human health, such as depletion of the ozone layer, loss of biodiversity, pressures on food-producing systems and the spread of infectious diseases globally.
Yes, our body try to adapt many of the changes that occur in our environment, however some of them are so serious leading to development of diseases like cancer, respiratory diseases etc.
Our body adapts to all changes, but consequences and the impacts on health are also seen on our body. Decrease in fertility level, skin problems, high rate of respiratory diseases even in toddlers, cancer, new viruses due to mutation etc. are some of the examples.
We will not only have to face the changes in our own body, but also the changes in animals and plants that we feed on. Agriculture and livestock will be seriously affected by plagues and unknown epidemics that will affect our own health.
