170:, especially natural influences on global temperatures. In 2009, Tsonis, with Kyle Swanson, published a paper reporting that natural climate shifts are superimposed on the warming trend observed during the 20th century. They concluded that "a break in the global mean temperature trend from the consistent warming over the 1976/77–2001/02 period may have occurred." The authors also argued that "there are times when different types of natural variation in the climate synchronize, which shifts the climate to a new state", and that this may explain the supposed cessation of warming that, according to him, began in 2001 or 2002. They contend that this shift changed the climate state from "warming" to "cooling". Tsonis has argued that natural factors, especially ocean currents, may contribute more to climate change than human activity, and that the Earth is "now in a period of cooling that could last up to fifty years." In 2013, he reiterated his view that this cooling trend was occurring, and might continue for the next 15 years. That year, shortly after the
