Through out the geologic record CO2 had trailed temperature by 800 years. This is due to the sequestration of CO2 by the ocean.CO2 – the major cause of global warming

CO2 emissions are the major cause of global warming
Global warming is caused by the emission of greenhouse gases . 72% of the totally emitted greenhouse gases is carbon dioxide (CO2), 18% Methane and 9% Nitrous oxide (NOx). Carbon dioxide emissions therefore are the most important cause of global warming. Recent investigations have shown that...timeforchange.org
I don't know who trained you to parrot that, but you might wish to acquire a megaphone and educate NOAA, among other institutions. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.Repeat after me... there is no empirical evidence that CO2 causes climate changes. None, nada, zip.
Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. Fossil fuels like coal and oil contain carbon that plants pulled out of the atmosphere through photosynthesis over the span of many millions of years; we are returning that carbon to the atmosphere in just a few hundred years. According to State of the Climate in 2019 from NOAA and the American Meteorological Society,
From 1850 to 2018, 440 ± 20 Pg C (1 Pg C = 10¹⁵ g C) were emitted as CO₂ from fossil fuel burning (Friedlingstein et al. 2019). For 2018 alone, global fossil fuel emissions reached 10 ± 0.5 Pg C yr−1 for the first time in history (Friedlingstein et al. 2019). About half of the CO₂ emitted since 1850 remains in the atmosphere. The rest of it has partially dissolved in the world’s oceans… . While the terrestrial biosphere is currently also a sink for fossil fuel CO₂, the cumulative emissions of CO₂ from land use changes such as deforestation cancel terrestrial uptake over the 1850–2018 period (Friedlingstein et al. 2019).Climate Change: Atmospheric Carbon Dioxide
In the past 60 years, carbon dioxide in the atmosphere has increased 100 times faster than it did during the end of the last ice age.www.climate.gov
