When floods ravage Asian monsoon regions in summer, megadroughts often attack extratropical North America, which feature an intercontinental contrasting precipitation anomaly between Asia and North America. However, the characteristics of the contrasting Asian-North American (CANA) precipitation anomalies and associated mechanisms have not been investigated specifically. In this article, we fir...

Recent public debate and the scientific literature have frequently cited a "pause" or "hiatus" in global warming. Yet, multiple sources of evidence show that climate change continues unabated, raising questions about the status of the "hiatus". To examine whether the notion of a "hiatus" is justified by the available data, we first document that there are multiple definitions of the "hiatus" in...

The growth rate of climate forcing by measured greenhouse gases peaked near 1980 at almost 5 W/m(2) per century. This growth rate has since declined to approximately 3 W/m(2) per century, largely because of cooperative international actions. We argue that trends can be reduced to the level needed for the moderate "alternative" climate scenario ( approximately 2 W/m(2) per century for the next 5...

Very often, when I talk to the public or the media about “global warming”, they ask me if I believe in global warming. This unfortunate question is apparently very popular among scientists as well. And I say ‘unfortunate’ because when we are dealing with a scientific problem ‘believing’ has no place. In science we either ‘prove’ or ‘disprove’. We ‘believe’ only when we cannot possibly prove a t...

In a short period of time, climate 'geoengineering' has been added to the list of technoscientific issues subject to deliberative public engagement. Here, we analyse this rapid trajectory of publicization and explore the particular manner in which the possibility of intentionally altering the Earth's climate system to curb global warming has been incorporated into the field of 'public engagemen...

This paper addresses the relationship between climate change and aquaculture sector through comparing the contribution of developed and developing countries in gas emission (CO2) and aquaculture production. As long as aquaculture industry is vital source of food and revenue for most developing countries, their livelihood presumably would be affected negatively by global warming. Examining data ...
