Significant changes in plant phenology have been observed in response to increases in mean global temperatures. There are concerns that accelerated phenologies can negatively impact plant populations. However, the fitness consequence of changes in phenology in response to elevated temperature is not well understood, particularly under field conditions. We address this issue by exposing a set of...

One of the potentially greatest threats to human beings is climate change. Climate scenario modelling indicates that our environmental conditions will change with increasing speed in the coming years with one of the most significant changes being a warming of the global climate. However, although there will be warming on the global scale there will be large regional variations in climate that w...

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 ...

Abstract The response of plant leaf and root phenology biomass in the Arctic to global change remains unclear due lack synchronous measurements above- belowground parts. Our objective was determine phenological dynamics parts Eriophorum vaginatum its warming. We established a common garden located at Toolik Lake Field Station; tussocks E. from three locations, Coldfoot, Sagwon, were transplante...

The human population passed the 7 billion mark last month. As the population grows, the environment, which in turn is necessary for our survival, suffers as a result of increased demand for natural resources and global warming. Key to addressing these challenges will be new knowledge provided by the evolutionary and ecological sciences. But, alarmingly, these areas are underfunded, as Cyrus Mar...

OBJECTIVE To show how a mathematical model can be used to describe and to understand the malaria transmission. METHODS The effects on malaria transmission due to the impact of the global temperature changes and prevailing social and economic conditions in a community were assessed based on a previously presented compartmental model, which describes the overall transmission of malaria. RESUL...

We propose that past abrupt climate changes were probably a result of rapid and extensive variations in sea-ice cover. We explain why this seems a perhaps more likely explanation than a purely thermohaline circulation mechanism. We emphasize that because of the significant influence of sea ice on the climate system, it seems that high priority should be given to developing ways for reconstructi...

The most important driver of climate variability is the El Niño Southern Oscillation, which can trigger disasters in various parts of the globe. Despite its importance, conventional forecasting is still limited to 6 mo ahead. Recently, we developed an approach based on network analysis, which allows projection of an El Niño event about 1 y ahead. Here we show that our method correctly predicted...

Pressure influences both magma production and the failure of magma chambers. Changes in pressure interact with the local tectonic settings and can affect magmatic activity. Present-day reduction in ice load on subglacial volcanoes due to global warming is modifying pressure conditions in magmatic systems. The large pulse in volcanic production at the end of the last glaciation in Iceland sugges...
