Worldwide heat records have been broken again, with 2016 declared the hottest for a third consecutive year, a new report has revealed. 2016 was the hottest year on record globally for the third year in a row. Climate change was the dominant factor in driving the record-breaking heat worldwide.

Taking a global average of the land and sea surface temperatures for the entire year, NOAA found the data for "2016 was the highest since record keeping began in 1880," said the announcement.

Although many ecological properties of species respond to climate change, their evolutionary responses are poorly understood. Here, we use data from long-term demographic studies to predict evolutionary responses of three herbaceous perennial orchid species, Cypripedium parviflorum, C. candidum and Ophrys sphegodes, to predicted climate changes in the habitats they occupy. We focus on the evolution of sprouting probability, because all three species exhibit long-term vegetative dormancy, i.e. individual plants may not emerge above-ground, potentially for several consecutive years.

Moving to a low-carbon economy only way to tackle impact of global warming

Models and physical reasoning predict that extreme precipitation will increase in a warmer climate due to increased atmospheric humidity. Observational tests using regression analysis have reported a puzzling variety of apparent scaling rates including strong rates in midlatitude locations but weak or negative rates in the tropics. Here we analyse daily extreme precipitation events in several Australian cities to show that temporary local cooling associated with extreme events and associated synoptic conditions reduces these apparent scaling rates, especially in warmer climatic conditions.

Ocean surface warming is resulting in an expansion of stratified, low-nutrient environments, a process referred to as ocean desertification. A challenge for assessing the impact of these changes is the lack of robust baseline information on the biological communities that carry out marine photosynthesis.

Attempts to measure the impacts of climate change on agriculture must invariably rely on models that translate changes in climate to changes in agricultural outcomes. This need for models exists even when assessing the impacts of climate trends that have already occurred, since simultaneous changes in other factors that affect agriculture, such as technologies and government policies, preclude direct observations of impacts. Over several decades, many approaches to developing these models have evolved, with most falling into one of two camps.

Global warming could be responsible for killing trees that are thousands of years old

Climate change may cause the wing length of some birds to rapidly grow, according to scientists who warn that even small rise in temperatures may have a profound effect on various species.

The Arctic continues to amaze.
