They’re hard to define. (Must they always be surrounded by water? What about ecosystems isolated on tops of mountains?) They’re also hard to count. (What, if anything, is too small to make the cut? A Kelvin wave enters the Atlantic, boosting the 2020 hurricane season peak. The peak of the Atlantic hurricane season is coming.

Current forecasts show that it will directly coincide with a Kelvin wave and the Madden-Julian oscillation approaching from the west. This will create a unique setup, which could be dangerous for the regions from Carribeans to the United States. Global weather is a very complex system. It is the definition of chaos theory, with an infinite amount of influencing variables. Global weather dynamics are also different across the world. Spring Flood Outlook 2020.

Karttapaikka - Maanmittauslaitos. Medieval Warm Period. Northern hemisphere temperature reconstructions for the past 2,000 years The Medieval Warm Period (MWP) also known as the Medieval Climate Optimum, or Medieval Climatic Anomaly was a time of warm climate in the North Atlantic region that may have been related to other warming events in other regions during that time, including China[1] and other areas,[2][3] lasting from c. 950 to c. 1250.[4] Other regions were colder, such as the tropical Pacific.

Medieval Warm Period

Averaged global mean temperatures have been calculated to be similar to early-mid 20th century warming. Possible causes of the Medieval Warm Period include increased solar activity, decreased volcanic activity, and changes to ocean circulation.[5] Initial research[edit] Evidence exists across the world, often very sparsely, for changes in climatic conditions over time.

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health.

Plastic Sources

Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information. Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total. 90% of plastic polluting our oceans comes from just 10 rivers. Over the last decade we have become increasingly alarmed at the amount of plastic in our oceans.

More than 8 million tons of it ends up in the ocean every year. If we continue to pollute at this rate, there will be more plastic than fish in the ocean by 2050. But where does all this plastic waste come from? Most of it is washed into the ocean by rivers. The world’s 7.5 billion people, in one chart. Our world has never been more connected than it is today. Nearly two-thirds of the world’s population is plugged into the matrix, with over 4.4 billion internet users across multiple device types. We use these devices for work and for play—and social media has altered the way we interact both online and offline. Today’s infographic from Global Web Index compares key generational and regional differences of social media use based on data from nearly 114,000 internet users, highlighting how pervasive social media has become in our lives.
