Anyways, it's all good. I got bored of trying to dig up ten year old posts and webpages, so whatever. I still believe that even though humans do contribute in a small way to everything, this is all still a cycle of the Earth that we may never completely figure out.
Earth is billions of years old. We'll never figure it all out.

You would have wasted your time anyhow. You fell for the same thing so many people do, you were fed one report out of context and assumed that negated all the others.
Just because a person has nice hair doesn't mean their lung cancer went away. Just because one ice sheet has gained mass over the last 10,000 years does not change all the effects we see Humans have done to the climate in the last 150 years all over the planet.

There may be things we'll never know, but we know what our effect of dumping pollutants into the environment has had.

Why go round and round with the same points?
Go for the real culprit. Deflecting blame is what's important.
Climate change is a natural cycle. Covid leaked from a Chinese lab.
The fact they're killing us isn't what's important. Why should I have to do anything, it wasn't my fault?

And my point was that it really doesn't matter what the cause is or was, if it fucks you up - you DO something about it.
Even if it's all you know how to do at the time. Wear the fucking mask, reduce your CO2 emissions....

Antarctic is interesting. Yes, NASA reported ice gains greater than losses a few years ago. Even more interesting was that the melt that was occurring was thought to be more attributable to geothermal heating from beneath than to the troposphere. The mass of ice is so great that it deforms the earth around it, and thins the crust underneath it, bringing the surface closer to magma, so geothermal is significant. Even with that, it appears that some slopes were expanding. There's a lot of theories to why that are interesting.
Eventually, of course, sheer physics will make itself known and the warmer temperatures will start melting the ice caps. There's an unknown continent under there, compressed and waiting to spring free.

Perhaps, but if you've noticed, I do not do well with change. I hate it. I'm tired of having to adapt when I don't want to. Everything was fine and dandy until the turn of the millennium, and things have gone steadily downhill since.
I want the 80's and 90's back, so I can have the world I knew and loved.

IPCC steps up warning on climate tipping points in leaked draft report
Climate scientists are increasingly concerned that global heating will trigger tipping points in Earth’s natural systems, which will lead to widespread and possibly irrevocable disaster, unless action is taken urgently.
The impacts are likely to be much closer than most people realise, a a draft report from the world’s leading climate scientists suggests, and will fundamentally reshape life in the coming decades even if greenhouse gas emissions are brought under some control.
The Intergovernmental Panel on Climate Change is preparing a landmark report to be published in stages this summer and next year. Most of the report will not be published in time for consideration by policymakers at Cop26, the UN climate talks taking place in November in Glasgow.
A draft of the IPCC report apparently from early this year was leaked to Agence France-Presse, which reported on its findings on Thursday. The draft warns of a series of thresholds beyond which recovery from climate breakdown may become impossible. It warns: “Life on Earth can recover from a drastic climate shift by evolving into new species and creating new ecosystems … humans cannot.”
Tipping points are triggered when temperatures reach a certain level, whereby one impact rapidly leads to a series of cascading events with vast repercussions. For instance, as rising temperatures lead to the melting of Arctic permafrost, the unfreezing soil releases methane, a powerful greenhouse gas that in turn causes more heating.
Other tipping points include the melting of polar ice sheets, which once under way may be almost impossible to reverse even if carbon emissions are rapidly reduced, and which would raise sea levels catastrophically over many decades, and the possibility of the Amazon rainforest switching suddenly to savannah, which scientists have said could come quickly and with relatively small temperature rises.

Latest non-human victims of the excessive heat - our innocent roads! 
https://www.sfgate.com/weather/article/ ... 279055.php
$1:
It's so hot in the Pacific Northwest that roads are buckling.
Asphalt and concrete roadways are expanding and cracking and even Interstate 5 has been impacted amid a heat wave that has sent temperatures soaring to dangerous levels.
"There have been several instances of road impacts across Western Washington today, including along I-5 at times," the National Weather Service's Seattle office wrote on Twitter. "Additional impacts likely tomorrow with another day of extreme heat. Remain vigilant on your commutes!"
A state trooper shared images on social media of a damaged highway near Everson, Washington, about 10 miles south of the Canada border.
"State Route 544 milepost 7 near Everson, Wa is currently closed," read the message from the Washington State Patrol District 7. "The asphalt roadway is buckling and unsafe for travel. WSDOT is advised and detours are currently being set up."
A concrete panel popped up on a northbound section of Interstate 5 near Interstate 405 in Tukwila, 12 miles south of Seattle, according to the Washington State Department of Transportation.
The agency wrote on Twitter that heat equals expansion.
"Crews are removing the damaged panel and filling it back in," WSDOT shared. "No estimated time for getting these lanes and ramp back open. Fortunately, not much of a backup at the moment."
A historic heat wave is gripping the Pacific Northwest, pushing daytime temperatures into the triple digits, disrupting Olympic qualifying events and breaking all-time high temperature records in places unaccustomed to such extreme heat.
Portland, Oregon, reached 112 degrees Fahrenheit on Sunday, breaking the all-time temperature record of 108 Fahrenheit, which was set just a day earlier.
In Eugene, Oregon, the U.S. track and field trials were halted Sunday afternoon and fans were asked to evacuate the stadium due to extreme heat. The National Weather Service said it hit 110 in Eugene, breaking the all-time record of 108.

Temperature Extremes
As the climate continues to warm, changes in several types of temperature extremes have been observed (Donat et al., 2013), and are expected to continue in the future in concert with global warming (Seneviratne et al., 2012). Extremes occur on multiple time scales, from a single day or a few consecutive days (a heat wave) to monthly and seasonal events. Extreme temperature events are often defined by indices (see Box 2.4 for the common definitions used), for example, percentage of days in a year when maximum temperature is above the 90th percentile of a present day distribution or by long period return values. Although changes in temperature extremes are a very robust signature of anthropogenic climate change (Seneviratne et al., 2012), the magnitude of change and consensus among models varies with the characteristics of the event being considered (e.g., time scale, magnitude, duration and spatial extent) as well as the definition used to describe the extreme.
. . .
It is virtually certain that there will be more hot and fewer cold extremes as global temperature increases (Caesar and Lowe, 2012; Orlowsky and Seneviratne, 2012; Sillmann et al., 2013), consistent with previous assessments (Solomon et al., 2007; Seneviratne et al., 2012). Figure 12.13 shows multi-model mean changes in the absolute temperature indices of the coldest day of the year and the hottest day of the year and the threshold-based indices of frost days and tropical nights from the CMIP5 ensemble (Sillmann et al., 2013).

Arctic Circle is already recording 118 F degree days (and summer is just heating up)
$1:
On the summer solstice (June 20 — the longest day of the year) two European Union satellites recorded a scorching temperature of 118 degrees Fahrenheit (48 degrees Celsius ) on the ground in Arctic Siberia.
This isn't quite a new heat record; as a post on the EU's Copernicus satellite website noted, this egg-boiling temperature was detected only on the ground in Siberia's Sakha Republic, while the region's air temperature (the temperature people would actually feel while walking around) was a toasty 86 F (30 C).
However, that's still an anomalously high temperature for the Arctic Circle — and one that could exacerbate the region's melting permafrost, which is the only thing preventing ancient caches of greenhouse gases from reentering Earth's atmosphere, according to Gizmodo.
The EU's Copernicus Sentinal-3A and 3B satellites recorded the high temperatures in the midst of an ongoing heat wave over much of Siberia. The heat spike is, unfortunately, a predictable start to summer, following a spring that saw hundreds of wildfires scorching the Siberian countryside and blacking out major cities with blankets of smoke.
Many of these spring fires were "zombie fires," so named because they are thought to be the rekindled remains of wildfires that ignited the previous summer and were never fully extinguished. The zombie fires smoldered for months under winter ice and snow, fed by the carbon-rich peat below the surface. When the spring melt arrived, the old fires blazed anew, Live Science previously reported.
If last summer is any indication, the hot solstice temperatures are just the beginning. Precisely one year ago, on June 20, 2020, the same region of Siberia recorded the first 100 F (38 C) day above the Arctic Circle — the hottest temperature ever recorded there. The sweltering day in Siberia fits into a larger climate change trend. For years, average temperatures in the Arctic have been rising at a far faster rate than anywhere else on Earth, largely due to melting sea ice induced by man-made global warming.
