My Take on Climate Change by City Tech Blogger Jialun Xiao

In general, it is true that the global climate is warming, and that this warming is caused by human emissions of greenhouse gases. However, time scales need to be emphasized: on inter-annual to decadal scales, such as climate systems that include the El Niño-Southern Oscillation, and independent events such as volcanic eruptions (cooling of global temperatures). Human greenhouse gas emissions will continue to raise temperatures above natural fluctuations which should raise concern to the world.

Although we are aware that greenhouse gas emissions have caused climate warming, it is difficult to determine whether the current climate warming is due to human influence. In my opinion, the solution is to conduct controlled experiments comparing situations with and without human influence to confirm whether or not global warming is man-made. Unfortunately, the global climate is a huge and complex system, and it  will take years to fix the climate change disaster. There is no theory that can be used in one sentence to explain everything in words, but there are exceptions and details that we should  pay attention to.
