Issue: Global

Summary:
"An International research team has discovered that seasonal temperatures in Europe, above all in winter, have been affected over the past 500 years by natural factors such as volcanic eruptions and solar activity, and by human activities such as the emission of greenhouse gases. The study could help us to better understand the dynamics of climate change."
It is now an understood fact based on research that the volcanoes, human impacts, as well as solar radiation all play a part in climate change on a level related to one another. Through Earth projection modeling, we can tell how things like volcanoes have influenced climates in the past, and how they can influence it in the future.


Opinion:
If  the three factors of human impacts, volcanoes, and solar radiation are on par with one another, it would be best to first figure out how EXACTLY do they influence the climate, and in what way. Afterwards we can focus on how we can use this knowledge to our advantage to maintain a balanced climate.
