There is overwhelming scientific consensus that the climate is changing due to primarily human-induced activities. Emission of greenhouse gases from the energy and construction sectors is one of the main human induced causes. Most legislative and policy initiatives by countries to deal with climate change will have a significant impact on the energy and construction sectors. In proposing the appropriate sustainability lessons for Singapore's construction industry, this paper briefly examines the international framework for dealing with climate change and the key legislative and policy initiatives in the USA and Australia, two of the largest GHG emitters in the world. This paper argues that the relevant mechanism introduced in all three countries is insufficient to deal with the impacts of climate change, as their main focus is on mitigation. The most rigorous mitigation efforts currently might not be able to prevent climate changes in the near future; hence, adaptation to climate change should become an integral part of the planning process, especially in the construction sector.

Climate Change Threatens Coral
For many years environmentalists have stressed the importance of coral to the environment. Scientists estimate some kinds of coral have existed on earth for hundreds of millions of years. Currently, though, anthropogenic activity, especially CO2 emissions, pose a significant threat to coral populations. Coral reefs are irreplaceable; by implementing conservation strategies, protection plans, and climate change mitigation strategies, we can help preserve some of the most invaluable organisms on the planet. What...
Climate change is more than a tech problem, so we need more than a tech solution
At the COP 21 climate convention in Paris at the end of 2015, leaders from 194 nations agreed to pursue actions that will cut greenhouse gas emissions enough to keep global warming within 1.5 °C (2.7 °F) above pre-industrial conditions. Meeting this goal will avoid continued and increasing harm to people and ecosystems around the world caused by a changing climate, and it is also a great opportunity to turn the world into a place that embodies our collective and pluralistic values for the future. Neverthele...
Climate change to worsen drought, diminish corn yields in Africa
Original story at MIT News Nearly 25 percent of the world’s malnourished population lives in sub-Saharan Africa, where more than 300 million people depend on corn, or maize, as their main food source. Maize is the most widely harvested agricultural product in Africa and is grown by small farmers who rely heavily on rainwater rather than irrigation. The crop is therefore extremely sensitive to drought, and since 2015 its production has fallen dramatically as a result of record-setting drought conditions...
Financing urban adaptation to climate change
Municipalities across Europe increasingly acknowledge the need to adapt to climate change and have begun to adopt various measures. Meeting the costs of adaptation measures for climate change is, however, a major challenge. Municipalities have found innovative ways to overcome that challenge and have started implementing measures. These solutions could be relevant for other cities, towns and smaller municipalities too, and examples are collected and presented in this publication as an inspiration. It offers...
Transformational adaptation – when climate change means business as usual is no longer possible
1. A lesson from the past Deep in the central Sahara, a crumbling mud-brick town sits at the edge of a dry lake bed. This is the medieval town of Germa, in southwestern Libya, one of a string of settlements along the Wadi al-Ajal, a valley defined by the towering dunes of the Ubari Sand Sea to the north, and the black cliffs of the Messak Settafet plateau to the south. Germa is romantic and impressive, but a more interesting settlement lies beneath it. Under medieval Germa, the remains of large stone buildings...
