Climate change. In writings as early as 1883 (and through to the end of his life) Russell repeatedly expressed the view that the world's climate would gradually but significantly change as a prelude to the re-establishment of Eden-like conditions. These changes, he said, would include the gradual melting of the Greenland ice sheet, the Arctic and Antarctic polar ice caps, and the general warming of the earth. 
I think His Christian Zionism teachings also explain why jehovah's witnesses seem to mirror judeism in there beliefs.
Christian Zionism. Expanding upon an idea suggested by Nelson Barbour, Russell taught as early as 1879 that God's favor had been restored to Jews as the result of a prophetic "double" which had ended in 1878 (favor from Jacob to Jesus, then disfavor from Jesus until 1878). In 1910, he conducted a meeting at New York's Hippodrome Theater, with thousands of Jews attending. Jews and Christians alike were shocked by his teaching that Jews should not convert to Christianity. Russell believed that the land of Palestine belonged exclusively to the Jewish race, that God was now calling them back to their land, and that they would be the center of earthly leadership under God's Kingdom. Early in Russell's ministry, he speculated that the Jews would possibly flock to Palestine and form their own nation by the year 1910. Shortly before his death, he utilized the Jewish press to stress that 1914 prophetically marked the time when Gentile nations no longer had earthly authority with the result that all Jews were, from that time onward, permitted and guided by God to gather to Palestine and boldly reclaim the land for themselves.
edit no I do not think he was correct
