Check out this awesome global population density heatmap

global-population-density-heatmap-world

Population density maps tend to be boring and ugly. Róbert Szűcs, a GIS Analysis from Hungary had the same feeling and decided to change it. He took the population density raster available at NASA, did a bit of experimenting with QGIS, then he made a color relief version using GDAL and imported this into TileMill, where he finished the map.

The map can be a real eye-opener for a westerner, seeing the relative ‘darkness’ of the Americas and even Europe, compared to India, Eastern China, the island of Java in Indonesia, or the last few hundred kilometres of the Nile. Also check how Sub-Saharan Africa is rising, with Nigeria, Ethiopia, Kenya, Uganda, Tanzania leading the way.

If you like the map you can buy it on Etsy.

Top 11 maps that ultimately explain climate change and its impact

Scientists and politicians all agree – climate change and global warming are not just myths. They are a fact. This compilation of maps will show you what are the reasons behind it and what are the consequences of that process.

An atlas of pollution: the world in carbon dioxide emissions

China overtook the US as the world’s biggest emitter in 2006. While the emissions in the Europe and the US fell substantially, China still sees a huge double-digit increase.

Global greenhouse gas emissions

Countries around the world are trying to get their greenhouse gas emissions under control. However in order to make it work everyone needs to be on board.

NASA visualizes the year of Earth’s CO2 emissions

Cool visualization by NASA shows the annual CO2 emission cycle around the Earth. The study shows that most of the CO2 emissions are generated on the Northern Hemisphere which corresponds to the location of the most industrial centres. The gases travel around the world to be largely absorbed by new vegetation in the springtime. In the winter the emissions start to take over the planet again.

Deforestation

Between 2000 and 2012 2.3 millions km² of forest have vanished. The greatest amount of loss still occurred in the tropics that count for 32% of all losses. While in Brazil due to political efforts the rate of loss reduced slightly (though after 2012 the restrictions for deforestation were loosened up again), the deforestation rate in Indonesia doubled after 2003 from 10.000 km² to more than 20.000 km² forest cut per year.

Global Temperature Rise

This cool infographic combines 167 global temperature maps—one for every year from 1850 to 2016—into a single chart. Blue signifies cooler temperatures (relative to a 1961-1990 reference period) and red warmer ones. If a cell is grey, it indicates there was insufficient data to determine its color for that year.

Ice cover is melting

Ice cover on the Poles and Greenland is quickly melting. In a few years most of the European glaciers might disappear.

Rising sea level

216 feet (66m) overall! Yup, that’s the level by which the sea levels are predicted to increase if all the ice melted into the oceans.

Animal migration because of the climate change

Global warming means the rising of the sea level but scientists predict that it will initiate a chain reaction of micro and macro effects in many different areas of life on our planet. One of them is the migration of animals. In order to survive over the next century many species will have to move to cooler or more suitable habitats. This map shows the trajectories that species are expected to take in the course of the coming decades as the climate changes.

The world getting warmer already cause disasters that devastate lives and cost hundreds of billions of dollars.

Climate change awareness

As much as 40 percent of the world’s adult population is unaware of climate change, according to a recently study. The awareness of threats related to that process is even lower.
