Sumatra region heats up as rainforests are razed for palm oil plantations – “The land use change does not only impact biodiversity and stored carbon, but also has a surface warming effect, adding to climate change”

By Hans Nicholas Jong 29 October 2017(Mongabay) – The wholesale destruction of rainforests across parts of Indonesia’s Sumatra island to make way for cash-crop plantations has not just devastated animal and plant biodiversity in the region, but may also be driving an alarming rise in temperatures on the ground, a new study suggests. Average temperatures […]

Tenfold increase in childhood and adolescent obesity in four decades – World will have more obese children and adolescents than underweight by 2022

LONDON, 11 October 2017 (WHO) – The number of obese children and adolescents (aged five to 19 years) worldwide has risen tenfold in the past four decades. If current trends continue, more children and adolescents will be obese than moderately or severely underweight by 2022, according to a new study led by Imperial College London […]

Histograms of daily maximum wet-bulb temperature, TWmax (°C), and maps of the ensemble averaged 30-year TWmax. (A) The histograms are generated for the most populous cities in the selected regions for each scenario: HIST (blue), RCP4.5 (green), and RCP8.5 (red). Values within each panel correspond to the 2- and 25-year return period of the bias-corrected annual maxima of TWmax, and the x and y axes indicate TWmax (°C) and the number of occurrences on a logarithmic scale, respectively. The background image was obtained from NASA Visible Earth. (B to D) The spatial distributions of bias-corrected ensemble averaged 30-year TWmax for each GHG scenario: HIST (1976–2005) (B), RCP4.5 (2071–2100) (C), and RCP8.5 (2071–2100) (D).

Climate change to cause humid heatwaves that will kill even healthy people

By Damian Carrington 2 August 2017 (The Guardian) – Extreme heatwaves that kill even healthy people within hours will strike parts of the Indian subcontinent unless global carbon emissions are cut sharply and soon, according to new research. Even outside of these hotspots, three-quarters of the 1.7 billion population – particularly those farming in the Ganges […]

IMF says global debt tops all-time high at $152 trillion

By David Lawder; Editing by Marguerita Choy 5 October 2016 WASHINGTON (Reuters) – The world is swimming in a record $152 trillion in debt, the IMF said on Wednesday, even as the institution encourages some countries to spend more to boost flagging growth if they can afford it. Global debt, both public and private, reached […]

The world is about to install 700 million air conditioners – “Demand for cooling, particularly in hot climates, is going to be an incredible driver of electricity requirements”

By Chris Mooney and Brady Dennis 31 May 2016 (Washington Post) – As summer temperatures finally settle in, many in the United States take it for granted that they can dial down the thermostat: Americans use 5 percent of all of their electricity cooling homes and buildings. In many other countries, however — including countries […]

Status of polar bear populations for 2014

24 January 2015 (Polar Bear Specialist Group) – The present table was discussed during late fall and early winter 2014, and agreed upon by the group on 20 January 2015. This status table will be updated whenever there is new information available that is considered credible and valid by the group. This year’s status table […]

Graph of the Day: Carbon emissions and human population, 1751-2013

13 June 2015 (Desdemona Despair) – Data show that growth of human carbon emissions in the modern era is pretty close to exponential (cf. “Graph of the Day: Global carbon emissions from fossil fuels, 1751-2013”). But what about carbon emissions per person? The Carbon Dioxide Information Analysis Center (CDIAC) maintains a database of fossil-fuel CO2 […]

The deadly combination of heat and humidity

By Robert Kopp, Jonathan Buzan, and Matthew Huber 6 June 2015 (The New York Times) – The most deadly weather-related disasters aren’t necessarily caused by floods, droughts or hurricanes. They can be caused by heat waves, like the sweltering blanket that’s taken over 2,500 lives in India in recent weeks. Temperatures broke 118 degrees in parts […]

Graph of the Day: Worldwide population estimates of large-carnivore species

10 January 2014 (Science) – Worldwide population estimates of large-carnivore species. Error bars represent the low and high range of the estimates when available. Population estimates were not available for all species. Species ranges vary widely, and range sizes can have a strong influence on species population levels (table S1). Sources: Gray wolf (90), all […]
