Global Metropolitan Urban Area Footprints

Areas are drawn to reflect total urban built up area, including suburbs, and do not reflect municipal boundaries. Where one metropolitan region bleeds into another as part of a megaregion, as with New York and Tokyo, the area limits are drawn subjectively Populations are mean to reflect cities'metropolitan regions. Again, as with areas, results vary with sampling methods. All populations and areas below are approximate and intended for basic comparison purposes only.

Modelling The Indonesian Throughflow

Ocean currents flow along the surface with the trade winds and westerlies. However an even greater flow takes place at depth. This deeper system of flow is called the Global Conveyer Belt. It is driven by temperature and salinity gradients, and takes 1000 years to complete one cycle. Ecologists and oceanographers are particularly interested in a region of the conveyor belt called the Indonesian Throughflow, where ocean currents facilitate one of the most biodiverse regions on Earth. This biodiversity can be attributed to the Global Conveyor Belt passing across the complex ocean floor of the Indonesian Throughflow. The patterns of mixing waters are of particular interest to a variety of researchers. This simulation, known as CT-ROMS, was developed to better understand the mechanics of nature in this region. The patterns of intermixing that occur here support a series of coral reefs that a collectively referred to as the Coral Triangle. This region is recognized as the global ce

Billion-dollar weather and climate disasters by state (1980 - 2016)

The map below reflects a summation of billion-dollar events for each state affected. From 1980–2016, there have been 23 drought events, 24 flooding events, 7 freeze events, 81 severe storm events, 34 tropical cyclone events, 13 wildfire events, and 14 winter storm events with losses exceeding $1 billion (CPI-Adjusted) each across the U.S. Via NOAA

The only person to survive on our roads

The truth is that cars have evolved a lot faster than we have. The strongest man cannot hold himself from going forwards in a car accident because the forces are so great. The most significant part of the body for injury is the head. Our bodies are just not equipped to handle the forces in common crash scenarios. As much as we like to think we’re invincible, we’re not. The human body can only withstand certain amounts of force in a car accident. In fact, the impact forces of just 30km/hr are enough to be fatal – such as striking a pedestrian or a side-on collision with a tree. But what if we were to change? What if our bodies could cope with the impact of a crash? What might we look like? Meet Graham, the only person who can survive on our roads. Multiple nipples help protect ribs like a natural set of airbags. Graham’s brain is the same as yours but skull is a lot bigger with more fluid and more ligaments to support the brain when a collision occurs. Skull

Surging Seas: Risk Zone map

Climate Central’s Surging Seas: Risk Zone map shows areas vulnerable to near-term flooding from different combinations of sea level rise, storm surge, tides, and tsunamis, or to permanent submersion by long-term sea level rise. Within the United States., it incorporates the latest, high-resolution, high-accuracy lidar elevation data supplied by NOAA, displays points of interest, and contains layers displaying social vulnerability, population density, and property value. Outside the U.S., it utilizes satellite-based elevation data from NASA. It provides the ability to search by location name or postal code. The accompanying Risk Finder is an interactive data toolkit for the U.S. that provides local projections and assessments of exposure to sea level rise and coastal flooding tabulated for every zip code and municipality along with planning, legislative and other districts. Exposure assessments cover over 100 demographic, economic, infrastructure and environmental variables using d

Food Insecurity and Climate Change

This website allows you to explore how different scenarios of global greenhouse gas emissions and adaptation to climate change could change the geography of food insecurity in developing and least-developed countries. By altering the levels of future global greenhouse gas emissions and/or the levels of adaptation, you can see how vulnerability to food insecurity changes over time, and compare and contrast these different future scenarios with each other and the present day. Vulnerability to food insecurity in the present-day The climate and food insecurity index shown on this website is a measure of vulnerability of the food system to climate-related hazards. Vulnerability is calculated at a country level and is comprised of three components: - Exposure to climate-related hazards, - Sensitivity of national agricultural production to climate-related hazards, - Adaptive capacity a measure of capacity to cope with climate-related food shocks.

Between 1975 and 2014, the worldwide prevalence of adult obesity tripled

The researchers compiled data from 1,698 obesity-related studies, covering 19.2 million people in 186 countries. They then used the information to estimate the distribution of body mass index (BMI) for every country in the world, for every year from 1975 to 2014. Between 1975 and 2014, obesity rates increased from 3.2% to 10.8% for men, and from 6.4% to 14.9% for women. Those numbers translate to 105 million obese adults in 1975, and 641 million obese adults in 2014, as shown in the chart below. During the same period the world population increased from 4 billion to 7.2 billion.  The study also estimates that 2.3% of the world’s men and 5% of the world’s women are severely obese. In 1975, the prevalence of severe obesity was just a fraction of 1% for both genders. In the U.S., obesity rates for men and women are about the same, 34% and 35% respectively. For comparison, Egypt, Turkey, and South Africa have higher rates of female obesity than the U.S. But their obesity r

Environmental Performance Index 2016: How environmentally friendly are the world's nations in 2016?

The Environmental Performance Index ranks countries’ performance on high-priority environmental issues in two areas: protection of human health and protection of ecosystems. Within these two areas the Environmental Performance Index scores country performance in nine issue topics comprised of 20 indicators. Indicators in the Environmental Performance Index assess countries’ proximity to internationally established targets or, in the absence of agreed-upon targets, how individual nations compare relative to the best performing countries. The Environmental Performance Index gives decision makers information relevant to policy, allowing the comparison across countries, and over time.
