It's now official: 2014 was the warmest year in recorded history. According to two separate analyses by scientists at NASA's Goddard Institute of Space Studies (GISS) and the National Ocean Atmospheric Administration (NOAA), the globally averaged temperature over land and ocean surfaces in 2014 was the highest since 1880 when modern records started. And, with the exception of 1998, the 10 warmest years have all occurred since the beginning of the 21st century. Prior to 2014, the Earth's warmest years were 2005 and 2010. Since 1880, Earth’s average surface temperature has warmed by about 0.8 degrees Celsius — and the majority of that warming has occurred in the past three decades. This long-term warming trend is the direct result of human activity, says NASA. It is mainly being driven by an increase in carbon dioxide emissions and other greenhouse gas emissions released into the atmosphere from human activity. “This is the latest in a series of warm years, in a series of warm decades. While the ranking of individual years can be affected by chaotic weather patterns, the long-term trends are attributable to drivers of climate change that right now are dominated by human emissions of greenhouse gases,” said GISS Director Gavin Schmidt. But this doesn't mean that temperatures will keep increasing at a steady rate and that every new year will have record-breaking temperatures. There will be regional differences in temperature due to weather events such as El Nino and La Nina — natural weather phenomena that warms and cool the tropical Pacific. Year-to-year fluctuations will therefore still occur. “The globe is warmer now than it has been in the last 100 years and more likely in at least 5,000 years,” Jennifer Francis, a Rutgers University climate scientist, told Associated Press. “Any wisps of doubt that human activities are at fault are now gone with the wind,” she said.

This exquisite event has met millions supporters through the years striving to educate Australia's population on the benefits of green investments and Eco-oriented lifestyle. Being one of the greenest cities in Australia, Melbourne had been chosen to be hot of this year's Green Cities conference. The event was held at the Grand Hyatt Melbourne where world-leading Eco organizations and specialists joined forces in order to help reducing the carbon footprint of the country. The prime topics, which had been discussed in March 18 and 19, vary from researches on the benefits green buildings for the environment and nature diversity of Australia, to the development of sustainability strategies by the leading industries in the Southern Hemisphere. Main place in the debates took the presentation of Kent Larson, a researcher and director in MIT. Along with topics such as uncovering the opportunities for retrofitting existing buildings, intensely discussed were some outstanding researches on the effect the employees' satisfaction on the success of green building investments. Speakers such as Sean Chiao, the CEO of Buildings and Places and Ann-Kristin Karlsson, the director of WSP Sustainable cities were also an important part of Green Cities 2014 (@GreenCitiesConf). With a huge following and a great cause, the conference got a massive response in the residents of Melbourne inviting more and more organizations to take the path of sustainable living. But being part of a more verdant community is not new to the residents of Melbourne. Cleaning agencies, such as the housekeeping team Cleaning House Melbourne, have long ago adopted the cause of green living by offering Eco-oriented services and applying cleaning methods, well-known to be beneficial for the reduction of the country's carbon footprint. Still, there are goals we are yet to achieve in order to help the the world become a better place for all of us and the Green Cities conference took us one step closer to our aim.
