What would it be like to live in an ice age?

It depends where, the continental landmasses at higher latitudes would be covered by massive ice sheets. Therefore the life in the sections of the US and Europe that are close to the Ice sheets would ...

Esker vs. Kame vs. Drumlin - what's the difference?

Eskers are glaciofluvial deposits from sediment carrying subglacial tunnels. As the water emerges from a tunnel at the bed of an ice sheet or glacier it will slow down. Since the sediment movement ...

Remote sensing of glaciers, season for data collection

Looking around at some random articles, for example Karpilo 2009, Geissler et al 2021, Litt et al. 2019, and Racoviteanu et al 2008 my impression is that researchers primarily use images of the ...

Are we at the beginning of a Heinrich Event?

Definitely not. A Heinrich event requires massive ice sheets to grow and then collapse in the Northern hemisphere. The large outflow of icebergs that would result form such collapse would deliver ...

How would Earth map look like if all ice melts?

Calculated Earth is one of the better tools for this, you can either zoom in and get various flood stages or set a specific flood stage and see what would flood, it is in metric though so you may need ...

How old are Chile's fjords?

The Quaternary is definitely a good guess. But it is difficult to answer your question because the "age of a fjord" is a rather ambiguous concept. Also, I'll asume you are interested in the bedrock ...

Is there a mountain-shaped iceberg?

Ice being less dense than water, icebergs float to the degree they displace water, with about 1/8 of their mass above the surface. Icebergs are also dynamic, melting from exposure to sunlight, warm ...

Is 2,000 years from now a credible figure for return to glaciation?

It's a little dated and brief, but it's a cool article and I believe it's overall sound in it's predictions and arguments presented. On the overall point, the author isn't predicting an ice age in ...

Why would glaciers change its size? How to differenciate change in glacier size as a response to climate and its natural dynamics?

To understand the problem there are a few fundamental conditions we need to realise. First, we can look at the climatic aspect of a glacier. In this example I will focus on mountain or valley glaciers ...

How do you estimate the depth of a lake?

You may as well ask if you stand on the coast of east Africa, the Arabian peninsular, Iran, west coast of India, or the southern tip of India, the west coast of Sumatra, the east coast of Madagascar, ...

Difference between downwasting and dynamic glacier response to climate change

Downwasting refers to glacier thinning due to melting ice. The statement seems to try to clarify the ambiguity that occurs when glacier changes are studied using non-stereo satellite images. With such ...

How to judge a good journal for glaciology?

A first approach would be to look at the reference lists of some good articles on glaciology. The reference list should contain several articles from journals that would be of relevance. As a ...

How to improve this prediction about the climate in future?

The more carbon dioxide in the atmosphere the more global warming. The more global warming the more cloud formations that cool the earth [...] The effect of clouds on global warming is highly ...

How would Earth map look like if all ice melts?

The latest estimations of global land ice mass suggest they have enough water to rise sea level in 66.5 m. With this value you can go on and produce a global map (or one of you area of interest) at ...

Darwin theory about Japan and China

At the northern and southern ends of the Sea of Japan, there are only short stretches of very shallow sea separating Japan from the mainland. During the Ice Age which ended 12,000 years ago, sea ...

When would the next glaciation appear? Worst case

Milankovich cycles are steady predictors, so sometime in the next 24-50 thousand years. But "Glaciation" is a broad terms, glaciers take long time to accumulate, but they accumulate, EVEN ...

How do you estimate the depth of a lake?

IF (a big if) you can see enough local topography to estimate the underwater slopes, you can get some likely bounds. If the lake had filled yesterday, projecting the slopes on either side until they ...

Effect of eccentricity and axial precession on glaciation/deglaciation

Does high eccentricity in combination with perihelion Northern Hemisphere summers (and hence aphelion winters) lead to deglaciation or glaciation? Paradoxically, it's the other way around, at least ...

Atmospheric $\ce{CO2}$ fell at a Pleistocene interglacial-glacial transition. Ocean absorption vs biosphere absorption

CO2 follows temp, not the other way around. When temperatures decline, biological activity decreases and available biologically derived carbon also declines. When temps increase and soil carbon ...

How are Quaternary alluvial deposits differentiated in subglacial latitudes?

They seem to be differentiated according to their morphology, Qof deposits being highly dissected and more consolidated than Qyf, thus older. From a random pamphlet of the map series: Qyf Alluvial ...

Can the shape and orientation of a large glacial rock deposit indicate glacial flow direction

Yes, it can. There are large, elongated mounds of till carried by the glacier as it advanced and left behind as it retreated. These mounds are called drumlins. Their long axis points along the track ...
