With the fast growth of Internet and cloud services, the need for more and larger data centers is also increasing globally. Data centers already consume significant amounts of electricity, and thus are responsible for significant amounts of CO2 emissions. Globally, about 600 million tons of CO2 emissions are contributed from data center operations alone, about 2% of total CO2 emissions. […]
The world wastes a lot of food. Make that a real lot – about 1 billion tons of food is wasted every year globally. Digest that for a moment. Can such a large amount of food waste be turned into something valuable? How about converting food waste into food – for animals? This is precisely what many innovative startups around […]
Today, climate change has become such a buzzword that people in all walks of life are using it. Most everyone who talks about has some vague idea that climate change is something quite worrisome, but only a few know what exactly it means. So, what indeed does Climate Change really mean? Before we talk about climate change, let us get the basics […]
As it turns out – lots of things. In fact, many of the causes for climate change are natural, and this is why our climate has been changing ever since the earth came into being some 4.5 billion years back, long, long before the remotest signs of human beings emerged! So, we humans had nothing to do with the climate change of the […]
Well, climate has been changing all the time since our earth was formed some four and a half billion years back. In the last one million years alone, there have been many significant changes in earth’s climate. The current warming trend is yet another example of climate change. Now, if you are one of those curious lot and are asking: “How […]
So what indeed is global warming? Is it just the increase in temperatures we experience in many parts of the world? Well, that’s a very simplistic and rather inaccurate definition of global warming. Sure, global warming does signify an increase in temperature of the Earth’s surface – both temperature on land and on oceans/water – as well as the temperature in […]
Global warming, a part of climate change, is caused by an increased greenhouse effect. Greenhouse effect is the effect caused by certain gases in the atmosphere classified as greenhouse gases. The main greenhouse gas is CO2. In the greenhouse effect, greenhouse gases trap heat. When sunlight reaches the surface of the Earth, some of it is absorbed and warms the ground, and some portion bounces back to […]
Global warming is a global problem, and one of the most serious ones at that. Naturally, the global body United Nations should play a key role in solving it? The UN indeed has been at the forefront of efforts to solve global warming. While the results of its efforts so far have been mixed, one can certainly say that it […]
How are the world’s climate change experts and leaders setting targets to control and manage climate change? Currently, the targets are being mainly set to control global warming, as that is the component of climate change that is of immediate urgency. And choosing global warming as the component to focus on makes sense too, as many other aspects of climate […]
If the earth is warming, is it getting warmer at the same rate everywhere? Well, I guess the intuitive answer is No, and that happens to be the correct answer too. Owing to global warming, Earth’s average annual air temperature – both on land and over sea – is rising, but not necessarily to the same extent in every single […]
