In an era when global biodiversity is increasingly impacted by rapidly changing climate, efforts to conserve global biodiversity may be compromised if we do not consider the uneven distribution of climate-induced threats. Here, via a novel application of an aggregate Regional Climate Change Index (RCCI) that combines changes in mean annual temperature and precipitation with changes in their int...

Tree taxa shifted latitude or elevation range in response to changes in Quaternary climate. Because many modern trees display adaptive differentiation in relation to latitude or elevation, it is likely that ancient trees were also so differentiated, with environmental sensitivities of populations throughout the range evolving in conjunction with migrations. Rapid climate changes challenge this ...

introduction land use change and climate change are the major concerns in the global environment. many environmental parameters affect the behavior of the earth’s climate system and its terrestrial components. effects of land use and land cover changes have direct influences on climate changes. now, climate change is known widely as a global health problem that has adverse impacts on natural an...

Anthropogenic forcings have contributed to global and regional warming in the last few decades and likely affected terrestrial precipitation. Here we examine changes in major Köppen climate classes from gridded observed data and their uncertainties due to internal climate variability using control simulations from Coupled Model Intercomparison Project 5 (CMIP5). About 5.7% of the global total l...

The Australian Drosophila Ecology and Evolution Resource (ADEER) collates Australian datasets on drosophilid flies, which are aimed at investigating questions around climate adaptation, species distribution limits and population genetics. Australian drosophilid species are diverse in climatic tolerance, geographic distribution and behaviour. Many species are restricted to the tropics, a few are...

The climate changes represent one of the major challenges in our century with major impact upon human being. This is the reason for which the study of the effects brought about by the climatic changes is one of the most current themes on international level. According to the meteorological events of the last years, Romania will be one of the most affected countries by the climate changes effect...

Many economic sectors, like housing or transportation, are exposed to climate and likely to suffer efficiency losses when climate changes. The global economy is far from being sheltered from climate, these sectors represent a significant fraction of the existing capital stock. Using an optimal growth model with perfect knowledge, we examine the balance between efficiency losses and investment i...

The present study analyzes the deployment of technologies to reduce CO2 emission in the global energy sector and the implied costs using the energy-economy-climate model ReMIND. The results depend on the policy chosen for inducing changes of investments. Climate policies price emissions and therefore induce changes of investments. The mitigation costs of less than 1% of GDP are relatively small...
