Could the current climate change events cause long-term problems in the viability of Earth to sustain life?
There are a lot of reports on the consequences of climate change for the relative short term. From what I understand, in the next 100 years or so, we will face:
global floods of coastal areas, causing large-scale migrations;
desertification of…

Is it ever possible for an continental plate to subduct under an oceanic plate?
It is well known that oceanic plates subduct under continental plates. This may be attributed to the plate's age and density, plus the water on top of it.
So I was wondering if it is ever possible for a continental plate to subduct under an oceanic…

How is sea level measured?
In comments on Earth changes due to global climate change, sea level changes is a common topic. I hear quotes about sea level changes in the centimeter and even millimeter range and wonder how such precision is even possible. The sea moves a lot;…

How much of arctic ice is from snow fall versus frozen sea water? I presume arctic ice comes from both sources.
Is there a way to tell how the ice was formed? In other words, if you made a core through the arctic ice cap, could you tell how much of…

How does the pole-to-equator temperature gradient scale with height contours?
Are the pole-to-equator temperature gradients lower at higher heights than at lower heights (like 850 mb/500 mb)?
If so, why is it the case? Especially given that the zonal circulation tends to be much higher at higher heights, so one could expect…

Why are the latest additions to the Hawaiian-Emperor seamount chain the highest?
The Hawaiian-Emperor seamount chain stretches from Russia to the Hawaiian islands. When I look at them on a map, it seems that the oldest seamounts by Russia are shorter and smaller than the newer seamounts/islands, and even in the most recent…

Do 360 day calendars affect climate models?
I was recently reading Zach Holman's blogpost on time and remembering that I've had to work with CMIP5 output that used a 360 day calendar, rather than a 365 day or a Greogrian (or Proleptic Gregorian) one.
Do models that store output in this…

When did wildfires start to occur on earth?
An oxidizer, fuel, and heat are needed for a fire. When considering oxygen as the oxidizer, an oxygen concentration of approximately 16% is required for combustion. Plant material is the fuel considered when thinking of a wildfire. A couple…

Carbon's role in ocean acidification
This might seem like a basic question, but I'm a little confused about the effects on ocean acidification of different carbon compounds.
I have heard that increased levels of carbon dioxide in the atmosphere are causing ocean acidification, lowering…

Is altitude of everything decreasing due to sea level rise?
We know that sea level is rising, though some people say climate change is fake.
Altitude is defined as the height of something measured from sea level.
Since sea level is increasing, and the heights of most things is not: is the altitude of most…
