(6)Carbon dioxide is only a very small percentage of the atmosphere (0.038%) and humans only contribute a small part of the total CO2 emissions in a year (less than 1%). Volcanos, on the other hand, produce more than all the cars and factories in the world. This means that human CO2 emissions cannot be the main cause of global warming.
(7)Solar activity is currently at a high level, and likely to be the cause of the current global warming. The mechanism involves cosmic rays aiding cloud formation, and the solar wind deflects cosmic rays away from Earth during periods of high solar activity. Solar activity levels are far more relevant than the small percentage of greenhouse gases being emitted by humans described in other theories.
(8)According to the work of Eigil Friis-Christensen, changes in solar activity match changes in global temperatures much more accurately than do changes in CO2 levels.
(9)The current warming is nothing unusual and was surpassed during the Medieval Warm Period. This was a time of great prosperity in Europe, highlighting the beneficial effects of increased temperatures.

(6)Carbon 二氧化物是唯一大氣(0.038% 的) 非常小百分比並且人只貢獻總二氧化碳排放的一小部份在一年(少於1%) 。火山, 另一方面, 生產更多比所有汽車和工廠在世界上。這意味著,
人的二氧化碳排放無法是全球性變暖的主要起因。(7)Solar 活動當前是在一個高水平, 和可能是當前全球性變暖的起因。機制介入宇宙射線援助雲彩形成, 並且太陽風從地球偏轉宇宙射線在高太陽活動的期間。太陽活動程度比溫室氣體的小百分比相關的由人散發被描述在其它理論。(8)According 對Eigil Friis-Christensen, 變化工作在太陽活動比賽上更加準確地改變在全球性溫度比變化在二氧化碳水平上。(9)The 當前溫暖是□什麼異常和被超過了在中世紀溫暖的期間。這是偉大的繁榮的時期在歐洲, 突出增加的溫度的有利作用。

二氧化碳是佔大氣0.038% 且人類貢獻總二氧化碳排放少於1%,火山比所有汽車和工廠產出更多,這不是全球性變暖的主因。陽光可能是當前全球性暖化主因,成因為宇宙射線助雲形成及宇宙風使得射線偏斜遠離地球。當前溫暖並無異常比中世紀還好。歐洲工業繁榮對溫度的增加有影響。
