Massive changes in the Artic weather and ice levels happening

In the last few years, there have been a spate of reports on how global warming is continuing to march ahead, irrespective of the debate among countries and politicians about the steps needed to stop the emissions that contribute to global warming. Global warming is supposed to have a horrific impact on the ice levels of the polar regions and Greenland, with large scale reduction of the Artic and Antartic ice shelfs, along with melting of the huge amount of ice present in Greenland. This melting will release enough water to increase sea water levels, in turn devastating many low lying islands and low lying coastal regions. Scientists further fear that we are moving to an accelerated level of changes due to global warming, where global warming will become unsustainable (as an example, less ice covering the water means that the blue dark water will absorb more energy rather than the light reflected by white ice).
Global warming is already devastating the habitat of animals in the colder regions in the extreme North. The impact on polar bears is already pretty well known, but there are a whole range of animals that are affected (link to article):


The Arctic as we know it may soon be a thing of the past. That's the message from Eric Post, lead scientist of a new report into the effects of climate change on life in the Arctic. "It seems no matter where you look -- on the ground, in the air, or in the water -- we're seeing signs of rapid change," said Post in a press statement.
With the decline in sea ice and snow, animals usually seen at lower latitudes are being found in more northerly regions, including red foxes that have been displacing native Arctic foxes. Migratory caribou in low Arctic Greenland and elsewhere are declining in number as they have not been able to keep their calving season in synch with changes in plant growth. With the decline in caribou comes a knock-on effect to native Inuit hunters, according to the report's authors. Hotter summers could result in more insects and parasites that prey on the caribou, which could then also reduce the annual caribou harvest by local indigenous peoples.


This impact on animals and the native human populations is different from 'Survival of the fittest' since these are changes made by humans. Unfortunately, these are just an indicator of the impact of global warming, the changes are happening all around us.

5 Photo tips (centered around the morning and daybreak)

Tip 1 (Use weather reports): There is nothing more frustrating than getting up early in the morning for some good sunrise photos, and then getting thwarted by clouds or bad weather. Even while developing patience is a good thing, you should read up about local weather, to make sure that you know what the weather is going to be like.

Tip 2 (Getting a good sunrise photo): Related to the above point, clouds are not bad altogether. If you don't have totally overcast conditions, with some cloud cover, then you can get some great photos. The clouds, tinged with color from the rising sun, as well as the sun playing hide-and-seek among clouds can give some great photos.

Tip 3 (Look for morning shadows): The shadows tend to be much longer at sunrise and sunset, and there are some pretty amazing looking photos you can get if you try and get the play of light and shadows in your photos.

Tip 4 (Look for a body of water): If you are near a lake, river, or other water body such as sea / ocean, the photos you get of the rising sun (or setting sun) over the water looks superb. Even if you can see a huge number of photos of the similar subject, they are still great photos to take to improve your collection.

Tip 5 (Taking light readings): If you are sufficiently professional enough to take light readings when you shoot, don't do so directly for a location with the rays of the rising sun. Take light readings of nearby areas (such as water that is starting to get lit by the sun, or of the sky, or buildings where the sun is not directly lighting up the outside wall). And then, take a number of photos to check which reading gives you the best photo.

Stormy Weather

A boy walked to and from school daily. On one particular morning, the weather was questionable as clouds were forming and the sky was grey, but the boy made his daily trek to the elementary school anyway.

As the afternoon progressed, the winds whipped up and the thunder and lightning began to roll. The boy's mother was concerned that her son would be frightened as he walked home from school and feared that the electrical storm might harm her child.

Worried, the mother got into her car and drove along the route to her child's school. Upon finding her son, she noticed her boy was walking along just fine, but at each flash of lightning, the child would stop, look up and smile. More lightning followed and with each one the boy would look at the streak of light and smile.

Puzzled, the mother approached him in her car, lowered the window and asked him, "What are you doing?"

The child answered, "I am trying to look nice; God keeps taking my picture."
