Climate changes and emerging fungal infections

Background: Candida auris is a globally emerging yeast pathogen that has shown not only resistance to most anti-fungal drugs but also thermo-tolerance to temperatures higher than the mammalian’s body temperature. Although it has been only a decade since the fungus was identified, its spread of infections has been rapid and quasi-epidemics have been reported. Co-occurrences of the fungus infecti...

Photosynthesis and Global Change Can Climate Driven Changes in Photosynthesis Be Used to Predict Changes in the Rate and Temperature Sensitivity of Ecosystem Respiration?

INTRODUCTION Terrestrial ecosystem respiration releases approximately 60 Pg carbon into the atmosphere anually (Schimel et al 1995). This is a relatively large amount in comparison to the 7.1 Pg carbon released per year from fossil fuel combustion, cement production and land use changes. Terrestrial ecosystem respiration thus plays a critical role in determining net CO2 fluxes into the atmosphe...

Urmia Lake desiccation and the signs of local climate changes

The water crisis is one of the important issues in the Middle East countries. Many lakes are ‎drying up and/or facing critical situations, exerting tremendous impacts on the socio-economics ‎of their region. Lake Urmia, in northwestern Iran, currently is facing critical situations and is on ‎the brink of total ‎shrinkage and environmental disaster. This paper investigates the roots of crises ‎t...

Orbital changes and climate

At the 41,000-period of orbital tilt, summer insolation forces a lagged response in northern ice sheets. This delayed ice signal is rapidly transferred to nearby northern oceans and landmasses by atmospheric dynamics. These ice-driven responses lead to late-phased changes in atmospheric CO2 that provide positive feedback to the ice sheets and also project ‘late’ 41-K forcing across the tropics ...

Direct and indirect climate change effects on photosynthesis and transpiration.

Climate change affects plants in many different ways. Increasing CO(2) concentration can increase photosynthetic rates. This is especially pronounced for C(3) plants, at high temperatures and under water-limited conditions. Increasing temperature also affects photosynthesis, but plants have a considerable ability to adapt to their growth conditions and can function even at extremely high temper...
