Sputnik comes live from Sharm el-Sheikh as US President Joe Biden gives an address at the 27th United Nations Climate Change Conference (COP27).
Biden is expected to focus on his administration's efforts to build on the "unprecedented work" done by the US to cut emissions and help the most vulnerable to resist climate impacts.
