Week 1 - Climate Change course

Started this course today,

https://www.futurelearn.com/courses/climate-change-challenges-and-solutions


I learnt a few things I didnt know.

That Ice and Snow Reflects more from the Sun/Radiation than Deserts.

That that reflection is called an Albedo

Took a quote here about the feedbacks: 

The 3 feedbacks are water vapour, ice albedo and radiation (planck feedback). 
The key feedbacks to help the climate self regulate are the Atmosphere, hydrosphere (water, lakes, rivers) biosphere (plants) cryosphere (ice caps, sea ice, mountain glaciers) and the lithosphere (surface of the earths crust). All these components act together and are linked. 

I learnt That Climate is basically long term effects, 30 years plus, it was summed up in a good quote by this person: 


Mark Tyler


Climate is the long term data obtained from patterns and trends, this can be compared and measured to show change that may be occurring. Weather is the day to day component of the climate which provides measurable elements such as temperature, wind speed and rainfall levels.

And I took another quote below because that one worked for me too.


Juan Gabriel Correa Perez


The human activities are accelerating the climate change due to increase of the gases of the greenhouse effect that turn on the positive feedbacks such as the rise of temperature, acceleration of hydrology cycle and the radiation emitted. So, we need to think how are the natural negative feedbacks able to keep the energy balance and offset the effect anthropogenic

Some useful things, Liked it.
