Is climate change a ‘ticking time bomb’? It is no secret to anyone that our planet is warming but what many of us don’t know is why and perhaps more importantly the consequences it poses. The roots of our problem lie in the form of a simple molecular compound‚ carbon dioxide. In 1870 the amount of carbon dioxide in the atmosphere was 290 parts per million. 144 years later‚ to this very date‚ it has risen to over 400 parts per million. But why does this cause a problem you may ask‚ well it is

The Science and Impacts of Climate Change on the Maldives Science of global warming and climate change Anthropogenicly produced greenhouse gases has exacerbated global warming. The burning of fossil fuels and deforestation have resulted in almost doubling the amount of CO2 in the atmosphere. The concentration of CO2 has increased at a rate of 2.0 ppm/yr.‚ which is much faster than in pre-industrial times (1). This greenhouse gas absorbs long wave radiation heat emanated away from the earth which

Professor David Karoly School of Earth Sciences‚ University of Melbourne Some views from leaders • Ban Ki Moon “Climate change is the greatest threat facing humanity. It threatens to undo 50 years of our development work and it will impact the poor in the greatest sense.” • Barack Obama “We will respond to the threat of climate change‚ knowing that the failure to do so would betray our children and future

Topic: “There is nothing that we as individuals can do to prevent climate change”. During last several decades‚ industrialization and human activities have produced greenhouse gases (mainly carbon dioxide). These gases make the earth’s temperature higher that leads to more serious events‚ such as ice smelting‚ floods‚ storms and droughts. This is called “climate change”. Climate change would have significant impacts on environment‚ economy and the way we live so it needs to be prevented. In my

Abstract Human influences and pressure is triggering a range of environmental changes. These changes on the geography of the Earth within such a small time frame are unheard of‚ and may be irreversible. Climate change has a wide range of adverse effects on the natural world and manmade systems. The main concerns are the risks posed on the Earths geophysical and ecological processes. Many causes influence climate change with the main cause being increased atmospheric greenhouse gases. Other major

Climate change is one of the biggest problems facing the world today. Climate change refers to the changes of the climate in which bad phenomena that caused directly or indirectly by human activities. Global warming is one of the main factors that contribute to the climate change. Global warming occurs when heat trapped in the earth’s atmosphere that caused by excess greenhouse gases such as Carbon Dioxide (CO2)‚ Methane (CH4) and Nitrous Oxide (N2O). All of these gases form a layer in the atmosphere

1 CLIMATE CHANGE I have decided to talk about climate change for my first topic – as the weather at the moment is changing. There has been a hurricane overseas and we are getting some of it so the winds are very strong they say it can be up to 70mph some airports have been shut. Windy rainy days but still very humid. Sunny and windy days but cold. Climate measures the average pattern of variation in temperature‚ humidity‚ atmospheric pressure‚ wind‚ precipitation. Climate is different from weather

Not surprisingly‚ therefore‚ the HRM concepts and practices being created and carried Ollt today are also increasingly different from those of the past.

Why climate change is good for the world Don’t panic! The scientific consensus is that warmer temperatures do more good than harm Climate change has done more good than harm so far and is likely to continue doing so for most of this century. This is not some barmy‚ right-wing fantasy; it is the consensus of expert opinion. Yet almost nobody seems to know this. Good news is no news‚ which is why the mainstream media largely ignores all studies showing net benefits of climate change. And academics

To complete the Warming Debate analogy‚ I’ll add that to date‚ there is no credible evidence to demonstrate that the climatological changes we’ve seen since the mid-1800’s are outside the bounds of natural variability inherent in the earth’s climate system. Thus‚ any impartial jury should not come back with a “guilty”
