If you want to talk about
REAL global warming, look at Venus!

Actually any real global warming - runaway greenhouse effect - on Venus happened aeons ago; Venus isn't warming
now. It's surface temperatures are remarkably stable - the same temperature at night as day, the same whether at the poles or the equator iirc. Global warming on Earth is real right now.
In my childhood, the air temperature in my latitudes in the summer was an average of 20 to 25 degrees Celsius. Now I have grown up, and I see that now it is much hotter, and the temperature is from 30 to 35 degrees Celsius.
Arctic warming is approaching those kinds of levels of average warming in places but policy makers cannot base responses on anecdotal accounts. We need better than that - and climate scientist
do require and do use better. The frequency and intensity of extremes are significant data, along with the temperature averages and other indicators; climate science does look to all kinds of data.
Still, our personal observations and experiences do matter - they impact our sense of how important the issue is.
Having recently been through the most intense period of drought on record here (Eastern Australia - we got less than 30mm of rain across a whole year), that included exceptional bushfires, that got out of control
in Winter, global warming stopped being something hypothetical, for some far future. Unprecedented in timing, unprecedented in intensity as fires continued through Spring into Summer. According to firefighters, unprecedented in fire behavior - there were more and more intense fire tornadoes, and more fires creating pyro-cumulus clouds and storms with dry lightning, that started even more fires.
If you live in a cold climate a few degrees of warming may not seem like much - may
seem beneficial even (although I doubt it actually will be) - but where I live Summer heatwaves already get unbearable and fire risks are reaching unprecedented levels with 1.4C of local average warming (from 1C of global average warming); adding another 4 or 5C degrees cannot be viewed as anything but catastrophic. I suspect that could be enough for heatwaves to kill crops, livestock and wildlife outright.
Even the warming of
Winter temperatures has problem impacts here, from perennial noxious weeds that were kept in check by frosts, now growing all year (once we got some rain again), requiring more work and expenditure to deal with them, to making Winter burning of grass and bushland for bushfire fuel reduction difficult (to reduce hot weather fire risks) with additional labour and equipment and expenditure requirements to do it safely. I cannot treat it as some kind of hypothetical possibility any more.
