Oscillation as part of the northern hemisphere. There are factors that bring warm weather to North America and some of Europe, taking it away from the Arctic. This cycle is reversed in other years. It will influence the temperatures in a certain area but won't affect global weather greatly.
HUMAN-INFLUENCED CLIMATE CHANGES The effect humans have on the climate is called our anthropogenic influences on climate. We have a significant impact on ecosystems, the biophysical environment, natural resources, and biodiversity throughout the world. Our impact has led to global warming, loss of environmental resources, mass extinction of some species, crises in our ecological systems, acidification of our oceans, and loss of biodiversity overall. There is much talk about how we have impacted or will continue to impact the environment and our climate. Let's look at the different factors related to anthropogenic influences on the earth and its inhabitants: •
Overconsumption – this involves our use of resources beyond the capacity of the earth to provide them. There are things we over-consume that cannot be easily replaced, such as petroleum products. Lifestyle issues and the overpopulation of parts of the earth both impact the problem of overconsumption. This is why we talk about reducing the carbon footprint. Carbon is the basis of petroleum products. We also overuse metals at too high a rate.
•
Overpopulation – human population growth has been significant in the past three hundred years compared to the millennia prior to this. So many people need to be fed and taken care of; this takes a toll on the world's resources. When we add the use of synthetic materials and items to be thrown away and not recycled to the problem, there is a big strain on the ecosystem. Resources are strained already and are expected to get more strained over time.
•
Farming and fishing issues – these involve poor agricultural practices that worsen the amount of emissions into the environment. Fishing will worsen the sustainable resources by overfishing or by damaging or destroying other species in the quest for getting the desired fish species. It is estimated that we will run 154
