Doesn't look like it, at least this time.
We've changed the sky. aka the atmosphere, by adding carbon-containing molecules to it. We've known about the heat-retaining properties of CO2 since '58. In '96, Arrhenius published his first global warming paper. and theorized that doubling CO2 would cause temperatures to rise 1.5-5 degrees C. The IPCC, with 120 years of data, says pretty much the same thing; 1.5-4.5, IIRC.
Abstract
The contribution of Eunice Foote (1819–1888) to early understanding of the relationship between atmospheric gases and climate change has become a focus of interest in the scholarly community and more widely on social media. In this article we offer a detailed interpretation of both of her known published papers, focusing particularly on her first and most significant paper of 1856, in which she related changes in the types and amounts of atmospheric gases, including carbon dioxide, to warming and changes in climate. We trace the derivation of her ideas and explore how she constructed, carried out, and interpreted her experiments.

Pre-industrial CO2 is 280; we're half way to doubling. We've already hit 1.5 degrees C monthly average above pre-industrial a few times. We've had La Nina for the last few years. Next El Nino, we'll have a record warm year.
