Global warming and climate change could in fact bring back an old stating back into circulation: “Water, water everywhere but not a drop to drink” Fresh water is crucial to human society – not just for drinking, but also for farming, washing and many other activities. It is expected to become increasingly scarce in the future, and this could at least […]
Interestingly, volcanoes can have both a cooling and warming effect on the planet’s climate. When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of these, such as ash and sulphur dioxide, have a cooling effect, because they (or the substances they result in) reflect sunlight away from the earth. Others, such as CO2, cause […]
The world emits about 35 Giga-tons (billion tons) of CO2 every year owing to human activities. But CO2 is not the only greenhouse gas. There are half a dozen other greenhouse gases we should be worried about as well. So, how much does the world emit of the other greenhouse gases? Apart from CO2, the other prominent greenhouse gases and […]
The Clean Development Mechanism (CDM) is an incentive policy framework designed to reduce the amount of greenhouse gas emissions. CDM is one of the flexible mechanisms defined in the Kyoto Protocol (IPCC, 2007). The CDM allows emission-reduction projects in developing countries to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2. These CERs can be traded […]
All along history, while a few wars have been fought over ideologies, most wars had resource acquisition and exploitation at their core. With climate change and global warming likely to have significant adverse effects on natural resources, it is only likely that these too could become causal factors for wars worldwide. Let us explore this topic a bit further. Environmentalists […]
Curbing the world’s huge and increasing appetite for meat is essential to avoid devastating climate change, according to many studies. Hello! What has eating the delicious meat got to do with climate change? You might want to know this fact: Estimates suggest that the global livestock industry produces more greenhouse gas emissions than all cars, planes, trains and ships combined! The total […]
Which industrial sectors emit the most CO2? Here is the list that provides an approximate estimate of the various sources and their contribution to CO2 emissions:
Carbon price is a cost applied to carbon emissions, in order to encourage emitters to reduce the amount of greenhouse gas they emit into the atmosphere. Economists and policy makers broadly agree that introducing a carbon price is the most effective way for countries to reduce their emissions. Climate change is considered a market failure by economists, because it imposes huge costs and […]
If you thought that the only way global warming would directly affect human health is through hot temperatures and heat waves, think again! Rising greenhouse gas levels and global warming are triggering climate and environmental changes that will affect human health in many ways. Climate change brings with it an increase in malnutrition, mental health conditions, infectious disease spread and even […]
Given that any analyses of climate change and global warming require researching a diverse range of inputs, how do scientists and climate change experts approach data collection and analyses? To a significant extent, the work of scientists so far had been to confirm cause-effect relationships – that it, to ascertain the extent to which each greenhouse gas resulted in global warming, and […]
