英国代写留学生作业:自然循环

全球变暖是近年来人们关注的一个趋势,它描述了人类活动和其他因素导致的气候变化。在今年的物理课上,我了解到建立模型是为了帮助科学家预测地球未来的气候状况。这些变化包括但不限于温室气体成分的变化、火山活动和地球轨道的周期性变化。虽然地球变暖是由某些自然力量造成的,但科学家认为,自从工业化开始以来,人类一直在通过排放温室气体来加强这些影响。这些模型帮助我们了解地球当前的气候状况,这些模型可能在短时间内是准确的。在模型中会出现一些知识问题在我看来,可靠性和准确性是其中最重要的。一些专家声称,地球最终可能处于冷却阶段,而不是变暖。然而,由于有相对较多的证据支持地球变暖,这些主张很容易被反驳。但是,如果全球气候变化与人类无关,而且是不可避免的自然循环,那该怎么办?有一些促成因素,如太阳耀斑活动和火山活动的增加,这是不可避免的。尽管如此,这些模型表明,人类通过对全球变暖做出贡献,提高了这一速度,并显示出这种效应的快速性。

英国代写留学生作业:自然循环

Global warming is a recent trend that people are concerned about which describes climate change due to human activity and other factors. In physics this year I learnt that models are developed in order to help scientists predict the future climate state of our planet. These are, but are not limited to, changes in the component of green house gases, volcanic activity and cyclical changes in the Earth’s orbit. Though the warming of the Earth is caused by certain natural forces, scientists believe that humans have been enhancing these effects by contributing to the greenhouse gases since industrialization began. Such models help us know about the current climate state of the Earth and the models might be accurate for a short period of time. There are knowledge issues that are brought up in the case of models and reliability and accuracy are the most important of these in my opinion. Some experts claim that the Earth might end up in a cooling phase instead of getting warmer. However, because there is comparatively more evidence to support the warming of the Earth, these claims are easily countered. But what if the global climate change has nothing to do with humans, and it is an unavoidable natural cycle? There are some contributing factors like increased solar flare activity and volcanic activity which are inevitable. Nonetheless, these models suggest that humans have enhanced this rate by contributing to the overall warming and show rapidity of this effect.
