Excess nutrients, coupled with climate change, damage the most highly resilient corals

Experimentalists conducted a simulation of future conditions in the Red Sea caused by global warming and acidification, while simultaneously increasing levels of nutrients such as nitrate and phosphate. They found that when nitrate and phosphate were added, the coral thermal resilience was compromised while algal growth benefited from excess CO2 and nutrients. »

Floridians could far far more frequent, intense Heatwaves

By the late 21st century, if atmospheric greenhouse gas concentrations reach worst-case projections, Floridians could experience summer heatwaves three times more frequently, and each heatwave could last six times longer and be much hotter than at present, according to new research. »

Marine animals have been following their preferred climate for millions of years

Current global warming has far-reaching ecological consequences, also for the Earth's oceans. Many marine organisms are reacting by migrating towards the poles. Researchers have now discovered that marine animals have been migrating for millions of years when the temperature on Earth increases or decreases. »

Climate change impacts fragile river ecosystems

Research undertaken in South Africa's Kruger National Park (KNP) has shown that some of the world's most sensitive and valuable riverine habitats are being destroyed due to an increasing frequency of cyclone-driven extreme floods. »

Uncertainty in long-run economic growth likely points toward greater emissions, climate change costs

A challenge in estimating the extent and cost of damages from climate change over the next 100 years is developing forecasts of long-run economic growth. In a new study, researchers present a systematic method of integrating current models to develop forecasts of uncertainty in global and regional per capita economic growth rates through the year 2100. »

Global 2 degrees C rise doubles population exposed to multiple climate risks compared to 1.5 degrees C

New research identifying climate vulnerability hotspots has found that the number of people affected by multiple climate change risks could double if the global temperature rises by 2 degrees C, compared to a rise of 1.5 degrees C. »

Major shifts in global freshwater

A new global, satellite-based study of Earth's freshwater found that Earth's wet areas are getting wetter, while dry areas are getting drier. The data suggest this pattern is due to many factors, including human water management practices, human-caused climate change and natural climate cycles. »

New approach to global-warming projections could make regional estimates more precise

A new method for projecting how the temperature will respond to human impacts supports the outlook for substantial global warming throughout this century - but also indicates that, in many regions, warming patterns are likely to vary significantly from those estimated by widely used computer models. »

New phase of globalization could undermine efforts to reduce CO2 emissions

New research reveals the growth of carbon production from Chinese exports has slowed or reversed, reflecting a 'new phase of globalization' between developing countries that could undermine international efforts to reduce emissions. The study found that trade among developing nations -- known as South-South trade -- more than doubled between 2004 and 2011. »

How land use and climate change are driving species distribution shifts

Climate change is altering where species live all over the planet. With global warming, species are moving towards the poles and up elevation where temperature is lower. However, along with global climate change, the world is also experiencing massive changes in land use which may also impact where species live. Could both of these forces be influencing current changes in species distributions? »
