         | So sure, from the figures given in this post we're seeing
         | record antarctic sea ice anomolies, record sea surface
         | temperature anomolies and record temperature mean anomolies.
         | 
         | But what does this mean for the average person?
         | 
         | What portion of our farmland is no longer serviceable? What

         | 
         | How many people will have to move, find other sources of
         | food/water? What other severe downstream effects are coming
         | that I'm not even aware of? Severe weather? Flooding? Ecosystem
         | collapse?

         | I understand that this blog is likely more dedicated towards
         | the science behind climate rather than communication of the
         | consequences to the layman, but it seems that most science

         | the outcomes are likely to be.

         | That's the crux of the dilemma. It's too hard. Nothing in our
         | daily experience gives us an intuition for it.
         | 
         | For instance, the media often says "solving climate change
         | requires lowering emissions". Which gives the impression that
         | if we lower emissions we solve it.
         | 
         | But lowering admissions merely slows the speed at which the
         | problem worsens. To solve the problem we would need to go to
         | zero and then actually suck extra co2 from the atmosphere.
         | 
         | And total global emissions, the only number which matters, are
         | at a record high.

               | 
               | So, if you don't know, during winter there is almost no
               | sun in antartica (and even in the areas you can see it 3
               | hours a day like in the Kerguelen, it isnt absorbed that
               | much to to a low angle of incidence). So we clearly don't
               | care about random averages of the sea ice over a year,
               | but its state when the sun hit the water, in summer
               | (because the angle of incidence is higher, and also, the
               | sun almost never sets there).
               | 
               | That's why your data is correct, but misleading. What's
               | important isn't the ice sheet surface this winter, during
               | june-july-august-september (sorry to over-explain, but i

               | but how much ice was present last summer (this winter if

         | [1] Nine long and nearly continuous sea level records were
         | chosen from around the world to explore rates of change in sea
         | level for 1904-2003. These records were found to capture the
         | variability found in a larger number of stations over the last
         | half century studied previously. Extending the sea level record
         | back over the entire century suggests that the high variability
         | in the rates of sea level change observed over the past 20
         | years were not particularly unusual. The rate of sea level
         | change was found to be larger in the early part of last century
         | (2.03 +- 0.35 mm/yr 1904-1953), in comparison with the latter
         | part (1.45 +- 0.34 mm/yr 1954-2003). The highest decadal rate
         | of rise occurred in the decade centred on 1980 (5.31 mm/yr)
         | with the lowest rate of rise occurring in the decade centred on
         | 1964 (-1.49 mm/yr). Over the entire century the mean rate of
         | change was 1.74 +- 0.16 mm/yr. [0]
         | 
         | ----
         | 
         | We compare estimates of coastal and global averaged sea level
         | for 1950 to 2000. During the 1990s and around 1970, we find
         | coastal sea level is rising faster than the global average but
         | that it rises slower than the global average during the late
         | 1970s and late 1980s. The differences are largely a result of
         | sampling the time-varying geographical distribution of sea
         | level rise along a coastline which is more convoluted in some
         | regions than others. More rapid coastal rise corresponds to La
         | Nina-like conditions in the tropical Pacific Ocean and a slower
         | rate corresponds to El Nino-like conditions. Over the 51 year
         | period, there is no significant difference in the rates of
         | coastal and global averaged sea level rise, as found in climate
         | model simulations of the 20th century. The best estimate of
         | both global average and coastal sea level rise remains 1.8 +-
         | 0.3 mm yr-1, as found in earlier studies. [1]

         | Kemp et al. (1) note that recent Intergovernmental Panel on
         | Climate Change (IPCC) reports emphasize sub-2 degC scenarios.
         | Simultaneously, IPCC reports also overemphasize catastrophic
         | scenarios, as does broader discourse. For example, the
         | cataclysmic Representative Concentration Pathway 8.5 (RCP8.5)
         | and Shared Socioeconomic Pathway 5-8.5 (SSP5-8.5) scenarios--
         | now widely considered implausible (2)--account for roughly half
         | of the scenario mentions in recent IPCC Assessment Reports'
         | impacts (Working Group II) sections (Fig. 1A), similar to
         | underlying scientific literature (3). The SSP3-7.0 emissions
         | pathway, which Kemp et al. (1) use in their analyses, assumes a
         | world in 2100 heavily reliant on coal and with no climate
         | policy--an implausible future (3, 4). It projects vastly higher
         | emissions than the International Energy Agency (IEA) stated
         | policies scenario, which has continually been revised downward
         | in recent years (4) (Fig. 1B). [2]

               | The problem is the vast majority of this "adapt and

               | 
               | - Historically: a geologically remarkable period of

               | 
               | - More recent: abundant fossil fuels

               | I see this comment all the time but it's a very odd one.
               | As far as species go humans are very, very young and
               | survived very little, just about 300,000 years.
               | Additionally, like I said, we've only existed as a
               | species during one of the most stable climates in the
               | history of the planet.
               | 
               | One final point on the "people always think the world is
               | ending!" rhetoric. We've only really started seeing
               | strong apocalyptic thinking in the last several hundred
               | years. Let's say, for argument, that humans were wiped
               | out in the next 100 years. Alien scientists visiting
               | would see people thinking about the end times in the last
               | 1/300,000 of the species' existence to be fairly
               | prescient, even if they were off by several of their own
               | species lifetimes.
               | 
               | On top of that the writing on this topic is not without
               | merit historically. Revelations was written during the
               | Siege of Jerusalem, when things _were_ collapsing for the
               | world of the author. Most medieval apocalyptic literature
               | was written or based on the black death which wiped out
               | between 30-50 percent of Europe. Hardly irrational
               | beliefs that the world is ending based solely on
               | existential anxiety.
               | 
               | There's also an obvious logical fallacy in all this

               | think they have cancer, and they don't most of the time.

               | Reasoning:
               | 
               | - 19 countries with the highest number of ecological
               | threats are among the world's 40 least peaceful countries
               | including Afghanistan, Syria, Iraq, Chad, India and
               | Pakistan.
               | 
               | - Over one billion people live in 31 countries where the
               | country's resilience is unlikely to sufficiently
               | withstand the impact of ecological events by 2050,
               | contributing to mass population displacement.
               | 
               | - Sub-Saharan Africa, South Asia, the Middle East and
               | North Africa are the regions facing the largest number of
               | ecological threats.
               | 
               | - 3.5 billion people could suffer from food insecurity by
               | 2050; which is an increase of 1.5 billion people from
               | today.
               | 
               | - The lack of resilience in countries covered in the ETR
               | will lead to worsening food insecurity and competition
               | over resources, increasing civil unrest and mass
               | displacement, exposing developed countries to increased
               | influxes of refugees.

           | being acceptable than our current warming trend.
           | 
           | I'm not pretending that cooling via sulfur emissions is
           | without costs -- but e.g. if living at 2018 levels of sulfur
           | emissions (which were already 90% down from peak) can give us
           | 0.5C of cooling, that's a deal I'm willing to take,
           | especially in light of how hard it is proving to reduce
           | carbon emissions. It especially seems like we're hitting a
           | number of tipping points with warming, and if sulfur
           | emissions (or any other albedo-increasing intervention) can
           | keep us from crossing those lines, we should, in my view.
           | Would we be better off with 2014-level sulfur emissions?
           | 2008? At _some_ point, trading sulfur emissions for cooling
           | becomes a bad deal, and we shouldn't scale up without limit.
           | But is it a good direction to move from where we are now? I
