Blocked by someone trying to deny climate change, LOL!!!

As some of you may know, I've accumulated numerous graphs and images and links regarding climate change, and I readily deploy them to counter climate change deniers.

This onslaught of facts and figure can be dispiriting to some deniers, such as this one, who deleted many of my posts and blocked me! I'm sure there's room for a snowflake joke here somewhere, [b]LOL!!![/b]

I believe the Climate has changed, and is changing. Sometimes in good ways.
Sometimes in bad ways. Do you think we will ever be able to control the climate?

I hear that someone is working on ways to change the weather, but I don't know
if that would change the worlds climate.

@DogMan Yes, I think that the accumulation of greenhouse gasses over the last 100 or so years has had a measurable effect on temperatures. And the system has 'momentum,' so reducing CO2 outputs won't have an instantaneous effect; there's still more temperature rise baked in. Higher CO2 isn't really a problem; plants love it. Higher temps aren't a problem in most areas.

The problem is sea level rise due to glacial melting; mostly glaciers in Antarctica where most of the ice is. Many major cities are near sea level, and a two or three foot rise starts to become costly. For me, the argument is a cost-benefit argument: which is cheaper, erecting sea walls around many major cities and seaports, or reducing CO2 output?

A secondary effect is that some areas become drier and some wetter, so farmland that's good now might not be good in a generation or two. Supporting few million acres worth of failing farms isn't as big a deal as preventing floods in low lying cities.

@ElwoodBlues Has Antarctica been melting? I have heard about melting in the Artic.,
but not Antarctica.

@DogMan Here's a copypasta from my climate change parking place. Satellites in polar orbits pass over Antarctica and (with GPS to measure orbital altitude) can make detailed radar measurements of the "altitude" of the ice masses there. That's the source of the estimates mentioned below.

[quote]April 1, 2021. The Antarctic ice sheet's mass has changed over the last decades. Research based on satellite data indicates that between 2002 and 2020, Antarctica shed an average of 149 billion metric tons of ice per year, adding to global sea level rise.Apr 1, 2021
. . .
Areas in East Antarctica experienced modest amounts of mass gain due to increased snow accumulation. However, this gain is more than offset by significant ice mass loss on the West Antarctic Ice Sheet (dark red) over the 19-year period. Floating ice shelves whose mass change GRACE and GRACE-FO do not measure are colored gray.[/quote]

[quote]For Antarctica, BEDMAP2 and Bedmachine provides the most complete and up-to-date estimate of ice volume, and it is derived by combining thousands of radar and seismic measurements of ice thickness [2,3].

In fact, BEDMAP 2 is derived from 25 million measurements. Fretwell et al. 2013 estimated that the Antarctic Ice Sheet comprised 27 million km3 of ice, with a sea level equivalent of ~58 m. BedMachine estimates the sea level equivalent of Antarctica to be 57.9±0.9m [/quote]
