Yes, unless you believe in coincidences and can come up with the coincidental cause.
These days, almost everybody agrees that the climate is warming. However, there is still disagreement as to how much of the warming is human caused. I started this site with an open mind, and I am still reading studies and modifying what I previously thought. You can find my listing of climate warming causes on this page.
Almost certainly, most of climate warming is caused by humans. Any alternative theory must explain why temperatures stayed within a less than one degree C range for eight thousand years, but has been rising rapidly (and steadily, if you take pollution into account) since mid-19th century industrialization — by 1.8º C (3.2º F) as of this writing. If there is a non-human cause, it is a strange coincidence! I do not believe in such a coincidence. Do you?
Moreover, having studied every alternative possibility that I know of, I cannot find one that holds up scientifically. I give background relevant to the earth’s orbit, the sun, location in the galaxy, the oceans, and volcanos on my pages discussing climate science.
Present explanations of climate warming were not disproved during the COVID lockdown of 2020. Human CO2 emissions are only about 8 % of plant and microbial emissions1. (It’s these additional human emissions that throw the carbon cycle out of balance.) While human emissions drive the average yearly increases in CO2 emissions, natural causes are almost entirely responsible for the fluctuations. A 7% reduction of human emissions during COVID is far to tiny to be detected. A 7% drop in the yearly yearly human emissions is only a 1/2 percent of natural emissions. Yearly CO2 increases vary by up to fifty percent in years when human emissions are mainly unchanged.
The average human-caused CO2 increase each year between 1916 and 1923 may be 2.4 ppm. A 7% reduction would bring this down to 2.232. The 2020 CO2 emissions increase was less than this, only 2.0 ppm (parts per million), (down from 2.5 the year before; and it was far less than the 2016 emissions increase of 3.0)2.
Below are two graphs2 3showing how temperatures held steady for thousands of year, but have shot up by 1º C to 2016, and another 0.8º C as of this writing. This within the last 100 years.
See my discussion of the causes of climate warming here.
And as of this writing, despite all the publicity and efforts, on balance worldwide humans are accelerating climate warming and not slowing it. I discuss this here: Are we slowing climate warming?
On the page: What more can we do to reduce the rate of warming? and its sub-pages I discuss the importance of controlling methane, and why wind and solar efforts alone, though less controversial than nuclear, only can go part way to slowing greenhouse emissions.
And finally, I have many pages looking at possible but not actual causes of climate warming and the science behind the actual causes of the warming.
