Farms that stop surviving winter due to it being warmer? Please point to these farms, and the underwater houses whilst you're at it.

It changes climates in a variety of ways, commonly making wet areas dryer, dry areas wetter, and producing larger temperature variations. Here in Florida, the last two years have been some of the worst orange harvests on record due to frosts in the winter. These cold snaps are largely driven by the breakdown of the polar wind currents. > underwater houses whilst you're at it.

  Local climate change happens constantly. There is no scientific evidence that global warming is enhancing variations about the mean increase, which is 0.13C per decade for the global troposphere[0]. Local climate change, especially extreme year on year changes like in California, is not noticeably affected by global warming, and thereby not by the human contribution to the global CO2 increase.

    The frosts the last few years have been from arctic cold blasting south, which is directly attributable to the weakening Polar vortex [0], which is directly linked to higher global ocean temperatures and sea ice loss [1].

    And yet the frequency of floods has increased in the past decade due to high tide events, e.g. rising oceans waters. https://climate.miami.edu/the-complex-climate/flooding-events-increase-on-beaches/ https://climate.miami.edu/the-complex-climate/flooding-event...

      Miami Beach tide gauge readings haven't changed since the year that study was published. https://psmsl.org/data/obtaining/rlr.monthly.plots/1858.png https://psmsl.org/data/obtaining/rlr.monthly.plots/1858.png Also, do you really find that study credible? "tide-induced events increased by more than 400%" in one single year? Sea level rise is a slow and steady process, but these guys are claiming it tripled in the span of a single year. That hasn't been reported anywhere else.

        The plot you posted shows a clear growth over the last 20 years. > Also, do you really find that study credible? I just looked for a local study. In either case, South Florida just this year had "once in 100 year" floods. At this point I would need studies to prove climate change isn't a key driver.

        Yes, but that's not what I said. Sea levels do rise globally at a slow rate, but it can also be offset by the land itself rising and falling (isostatic rebound), by minor changes to instruments (because the actual changes we're talking about are tiny), temperature changes affecting the volume of the ocean etc. In that particular city and beach, you can see that tides went down between 2000-2005, then remained more or less stable until 2015, then went up a bit and stabilized at a new level. CO2 levels meanwhile go up very steadily. This data clearly doesn't indicate something CO2 driven given the various trends including declines that have happened within the time since the gauge opened in 1995. These look like natural changes, which are expected because especially when zoomed into these tiny differences everything is always changing. In either case, South Florida just this year had "once in 100 year" floods If they happen every 100 years then why is human CO2 emissions to blame? Even climatologists don't claim there was much CO2 impact in 1920 or 1820.
