How do oceans determine regional climatic conditions-Part II

Well, hello there!

I know it has been a while, but with the ever warmer summers that we have been having (thanks for that, by the way) I get extremely busy this time of year. Now that we are back we shall continue our discussion on the effects of oceans on the world climate, and subsequently, the contemporary world. This post is the continuation of the effects of oceans on regional climate. If you haven’t read it already, please do so by clicking here. Caught up? Good, let us continue.

How do oceans determine regional climatic conditions? Part I- Effect

This post is part of a series of posts written by Priyadarshan Pandey. 


Welcome back, watermen (no?)!

So, in the last couple of posts we talked about the reason for my importance, my structure on an atomic level and the properties it generates, and my role in sustaining life on earth. And we talked about my birth and cosmological significance. Today I would like to resume this conversation, but on a more local level (both temporally and spatially).

Reusing wastes: Epic ideas to tackle carbon emissions and climate change

The problems of rising carbon in the atmosphere, along with the changing climate is one of the biggest in the 21st century. These problems are so large scale, so beyond human control that many people have just made peace with the fact that the world as we know it will soon end (or worse, live in denial). When the problem is so huge? How can a few people make a difference?

Turns out, they can.

Positive feedback loops: Controlling global climate

(This is the fifth post in the “feedback loops” series.)


Climate is weather, over a long period of time. Unlike weather, climate is predictable. It has a number of factors like solar insolation, rainfall, temperature and latitude/altitude that controls it in a particular place. Also, climate encompasses a large area.

Because of the spatial and temporal extent of climate, and because of the large scale environmental factors that control it, you would not expect it to change much. Global climate, in fact, does regulate itself in the short period of a few years or decades. You will be hard-pressed to find massive climate shifts in this time period in the geological record. Climate changes are usually seen in the form of cycles; the cycle have a time period of 20,000-40,000 years. It also has smaller cycles, in the range of a few centuries as well.

These cycles are generally positive feedback cycles, with a specific threshold at each end. When that threshold is breached, the environmental factors generally change in a way that allows the cycle to reverse itself. In this, I’m going to explain this phenomenon by taking the example of glacier growth and glacier melting.

Ecological succession: What controls the climax community?

Climax community: the final community in the process of ecological succession. This stage of ecological succession has been the object of much scrutiny and attention from ecologists, merely because it is rare and so many different possibilities can theoretically arise, depending on the path of succession.

However, all our studies are shown that every climax community has a certain specific set of characteristics- Continue reading Ecological succession: What controls the climax community?
