If society continues to pump greenhouse gases into the atmosphere at the current rate, Americans later this century will have to endure, on average, about 15 daily maximum temperature records for every time that the mercury notches a record low, new research indicates.

That ratio of record highs to record lows could also turn out to be much higher if the pace of emissions increases and produces even more warming, according to the study led by scientists at the National Center for Atmospheric Research (NCAR).

In large parts of Europe and North America, the decline in industrial emissions over the past 20 years has reduced pollution of the atmosphere and in turn of soils and water in many natural areas. The fact that this positive development can also have negative implications for these regions has been demonstrated by scientists at the Helmholtz Centre for Environmental Research (UFZ) in the journal Global Change Biology. According to their findings, declining nitrate concentrations in the riparian soils surrounding the tributary streams of reservoirs are responsible for the increasing release of dissolved organic carbon (DOC) and phosphate and a deterioration in water quality. In the case of drinking water reservoirs this can cause considerable problems with respect to water treatment.

Climate change is one of the most serious threats facing the world today. With the effectuation of the Paris Agreement, there has been a rising interest on carbon capture and utilization (CCU).

A new study, led by Professor Jae Sung Lee of Energy and Chemical Engineering at UNIST uncovers new ways to make biofuel from carbon dioxide (CO2), the most troublesome greenhouse gas. In their paper published in the journal Applied Catalysis B: Environmental, the team presented direct CO2 conversion to liquid transportation fuels by reacting with renewable hydrogen (H2) generated by solar water splitting.

Half of all coral species in the Caribbean went extinct between 1 and 2 million years ago, probably due to drastic environmental changes. Which ones survived? Scientists working at the Smithsonian Tropical Research Institute (STRI) think one group of survivors, corals in the genus Orbicella, will continue to adapt to future climate changes because of their high genetic diversity.

“Having a lot of genetic variants is like buying a lot of lottery tickets,” said Carlos Prada, lead author of the study and Earl S. Tupper Post-doctoral Fellow at STRI. “We discovered that even small numbers of individuals in three different species of the reef-building coral genus Orbicella have quite a bit of genetic variation, and therefore, are likely to adapt to big changes in their environment.”

Rudy Boonstra has been doing field research in Canada’s north for more than 40 years.

Working mostly out of the Arctic Institute’s Kluane Lake Research Station in Yukon, the U of T Scarborough biology professor has become intimately familiar with Canada’s vast and unique boreal forest ecosystem.

But it was during a trip to Finland in the mid-1990s to help a colleague with field research that he began to think long and hard about why the boreal forest there differed so dramatically from its Canadian cousin. This difference was crystallized by follow-up trips to Norway.

This year is on track to become the hottest year on record, with global temperatures measuring 1.2 degrees Celsius (2.2 F) above pre-industrial levels, according to the World Meteorological Organization(WMO). 

Most studies of global climate change attempt to predict what might happen to the Earth as temperatures rise in future.  A new study representing an international collaboration by ecologists and conservation biologists shows that global changes in climate have already impacted every aspect of life on Earth, from genes to entire ecosystems. It was published in the prestigious journal Science on November 10, 2016. 

The research team, led by the University of Florida and with participation from the University of Hong Kong, showed that of a total of 94 ecological processes evaluated globally, 82% of them showed evidence of impact from climate change.  Land, freshwater and marine ecosystems and species have all been all affected, and consequential impacts on people could range from increased pests and disease outbreaks, to unpredictable changes in fisheries and decreasing agriculture yields. 

A commentary on what should be included in the next IPCC special interdisciplinary report on oceans and the cryosphere has been released today in Nature by Daniela Schmidt, Professor of Palaeobiology from the University of Bristol and Philip Boyd, a professor of marine biogeochemistry from the Institute for Marine and Antarctic Studies, University of Tasmania.

The IPCC is an international body which was set up in 1988 to assess the science related to climate change.

Currently on its sixth assessment cycle, the goal of the IPCC is to inform policymakers of the science on climate change, the impacts, future risks and potential options for adaption and mitigation.

The latest IPCC report had for the first time chapters dedicated to the Oceans. This year, the IPCC are going one step further with a special interdisciplinary report on the ocean and the cryosphere which will be published in 2019.

A full 30 percent of the world’s electricity generation comes under the umbrella of just nine energy companies, and they have just joined forces to ramp up technology investments aimed at decarbonization. The global, collaborative effort was announced earlier this week by the companies’ nonprofit organization, the Global Sustainable Electricity Partnership.

To be clear, the decarbonization announcement leaves plenty of wiggle room for “clean” coal and natural gas, at least in the near future. However, a look at the group’s sole U.S. member, American Electric Power, demonstrates that a Republican administration cannot stop the global transition to low and zero-carbon electricity.

Climate change has already impacted nearly every aspect of life on earth, according to a new study in the journal Science. Warming global temperatures have altered everything from entire ecosystems down to the individual genes of species.
