Despite worrisome issues regarding climate change, I think that there may be little benefit we humans or aquatic animals stand to gain as global climate changes. What do you think?????
yes, the colder region will get the beneficial effects from on going global warming, but the warmer and low laying developing countries will receive the burden.....
Your question seems to be asking whether humans and some aquatic species would benefit from warming climate. Under changing ecological conditions—including stresses—species benefit or suffer adverse consequences differentially. Except under extreme conditions (e.g., volcanic eruptions that wipe out all populations of all species in the immediate vicinity) we expect some species to be, on balance, winners and others, on balance, to lose some of the advantages they previously enjoyed.
People in some regions would benefit from warming conditions. In currently arid regions that experienced increased rainfall, for instance, conditions would likely support greater agricultural productivity, but under warmer, wetter conditions mosquito populations and the prevalence of mosquito-borne illness could increase. On the other hand, if areas with ample rainfall that are currently agriculturally productive and prone to mosquito-borne illness were to become more arid, the opposite would be true there.
Aquatic organisms represent a varied range of examples. Warming water would alter the ranges of aquatic species while potentially reducing cold water habitat. Warmer water holds less dissolved oxygen than colder water, which would increase stress on aerobic species. Thermal stresses could also present direct problems. Because temperature fluctuations are typically greater in air than water, aquatic species are often adapted to a more limited range of temperatures than terrestrial species, which means even slight temperature increases can be a problem. For example, coral reefs experience die offs as a result of temperature increases of several degrees that might seem trivial to humans.
The other consideration here relates to the rate of temperature change. Faster temperature increases place greater stress on species.
That’s a brief, varied overview, but I hope it’s helpful.
Worldwide, one of the two mega energy consumers is heating/cooling of indoor space (the other is mobility). Climate change may lead to less heating in colder areas and to more air conditioning in warmer ones. In my current place of residence heating needs may decline (but have not yet). Maybe someone has made the global sums.
As examples, warming has already caused a change in the distribution of fish species: species with boreal affinity have disappeared from catches on the north shore, while species with tropical affinity that had existed only on the shore south are increasingly present in catches on the north shore.
It is general perception that northern hemisphere countries will be benefited and southern hemisphere will loose. But many things are still uncertain and we can speculate on the basis of common man perceiving burns from current rate of cyclones, irrational rainfall pattern, seasonal changes calendar is mismatching and also duration also change specially winter and autumn. wild plants and animals are best indicators to show that there i some effect already started only needed to quantify and make strategy to counter it.
There is an advantage we stand to gain from climate change. For example organisms that thrive in areas with high temperature will have positive effect, while those that thrive in cold climate will have negative effect. So for those organisms that love heat or high temperature there will be explosive growth and reproduction. For example mangrove distribution is mainly influenced by temperature so during climate change there will be intense growth, expansion in population and migration to warm areas. Their expansion will increase their ecosystem services to man and the environment. In conclusion, there will be a ripple effect to other organisms globally.
