1. If we cannot limit it to 1.5 we will start to slowly see every species on earth succumb to worse and worse conditions rapidly as the planets atmosphere catches up to the amount of emissions we created

   Remember for the entire time many of you have been alive we have been putting 16 nuclear bombs into our oceans EVERY SECOND.

   A really good example of why we don’t see that energy transfer immediately is to imagine using terra cotta pots in your home in order to maintain a stable temperature, the water inside the pots is very stubborn and won’t change temperatures too rapidly letting it be cool in the heat and warm in the cold.

   Now imagine the ocean is the terra cotta pot and it is the only pot inside our entire home.

   When that pot heats up, with no actual “night” to cool it back down the water will stay hot.

   Every summer for the rest of your life will be hotter than the last Reddit.

   Every year we will see a growing number of species go extinct as they couldn’t handle extremely fast changing conditions.

   This is happening now and we all are on THE VERY EDGE of the catastrophic consequences of our actions.

   On a geologic timescale this entire species existence is a blink of an eye. On that same timescale what we did to our planet is quicker than a thought could have been formed and getting worse every day.

2. The implication of the amount of GHG already in the atmosphere (573 ppm, when all of the non-CO2 GHG are converted into their CO2 equivalents) is that 1.5C is going to be exceeded. Even 2C is going to be exceeded. That’s not some wildly pessimistic prediction, that’s the conservative prediction of the IPCC:

   >Note: The IPCC suggests that a constant concentration of CO2 alone at 550 ppm would lead to an average increase in Earth’s temperature of ~3°C (5.4°F).

   According to the link, we were almost there two years ago, when CO2 was 419 ppm and CO2e was 534 ppm.

   The only reason we’re not there yet is for the same reason a pot of water doesn’t come to a boil instantly when you put the burner on high underneath it — it takes a while.

   And every day, that number gets fractionally higher.

3. It means DEATH ! – To many animals and plants….
   And more than quite a few problems for humanity too !

4. It’s going to get worse before it gets better. What worse means depends on where you are. Southwestern US is going to get hotter and dryer, while the Northeastern US is going to get wetter. If temperatures reach 120F people will migrate in order to survive. Crop failures become more severe, leading to food shortages and higher prices. Closing of the southern border and stationing troops there will lead to armed conflict over migration and access to water. This is what the next 5 years will look like in the US.
