About "Catch & Research"

Welcome. I found my passion in ecological economics and fishing. They are all about pursuit of unknown and uncertain objects. I always enjoy the seemingly reckless pursuit itself. This blog is a record of my long journey in research and fishing. Your comments are welcome and appreciated.

Some Basics on Climate Change (1)

The effects of global warming are no longer a distant threat. Climate change is happening now in our generation. During the last century, the average surface temperature has increased by 0.74 ±0.18°C (Intergovernmental Panel on Climate Change, 2007). Figure 1.1 shows the positive trend of global mean temperature since the Industrial Revolution.

Climate change does not only mean abnormal increases in temperature, but it does mean disturbance of whole climate systems which many species have evolved to adapt to for millennia. It will indiscriminately affect everyone and everything on earth, and the impacts will be enormous and last for over 1,000 years (Matthews & Caldeira, 2008; Montenegro, Brovkin, Eby, Archer, & Weaver, 2007; Solomon, Plattner, Knutti, & Friedlingstein, 2009). The time has come to worry about survival of human civilization. Global efforts to mitigate the adverse impacts of climate change are underway, but it is difficult to see many positive signs that these efforts are making a real difference (Anderson & Bows, 2008, p. 17). Is there any hope that we can succeed in mitigating climate change?
