"On the whole, the trend of temperature growth is an objective process, it exists. The rise in temperature will be maintained at least until 2015," Alexander Bedritsky told RIA Novosti.
He said that a number of theories existed including that there could be a period of global cooling linked to the sun's activity. "None of the hypotheses can either be checked or discarded," he said.
"There is an opinion that Europe will freeze should the Gulf Stream disappear. I do not share such unequivocal opinions," Bedritsky said.
He urged, however, a reduction in industrial emissions into the atmosphere.
"Let us suppose that an increase in human activity and greenhouse gases has no affect on the climate. However, work to cut emissions should continue, as it is both fuel economy and a reduction in harmful emissions, as well as the development of alternative energy sources," he said.
The majority of climate change experts, environmental groups and organizations say that global warming is caused by greenhouse gas emissions due to human activity, which is causing significant damage to the Earth, a small minority, however, argue that the possible impact has not yet been proven.
