There you are! I was missing you.
Actually, imho, you are both partly right and partly wrong.
Earth heats and cools naturally over millenia. Humans have, until few thousands of years have made no more impact than other fauna have on the environment.
But, when humans reached various thresholds, in numbers, ability to change the land, build, we changed things in many ways.
Small ways at first. Then, in sufficient numbers, we hunted various animal into extinction. Changed landscapes, altering local microclimates.
Fast forward to the start of the industrial revolution. Millions of humans, burning, digging, building, became billions destroying forests, polluting rivers, lakes and oceans. Steam gave way to oil and bigger, more powerful machines that polluted and destroyed unrelenting until the air in the cities was brown and unfit to breath, the waters were poisoned from runoff from fertilizer and pesticides. A few weirdo "tree huggers" recognized what was happening. Explorer scientists, like Cousteau began to point out our errors. Environmentalism was born.
Now our interference with nature, by way of industry at all levels, drilling, digging, building, burning, terraforming, has accelerated the normal global warming far beyond what it would be if we never existed.
So, although the earth is warming naturally on it's own, we are responsible for the great and growing speed of global warming far in excess of what would be happening if we were hunter gatherers with a global population of a million or so.
The "camel" earth is already over loaded. We better start changing our way before we break the camels back. Cut pollution in all it's forms. I suggest we start with fossil fuels and plastics, and recycle like our existence relied on it. It
does! Whether you realize it or not we are all astronauts relying on the recycling of water, air, food, everything. Even our earthly remains!
