Air pollutants, such as ozone, have adverse impacts on human health and cause, for example, respiratory and cardiovascular problems. In the United Kingdom (UK), peak surface ozone concentrations typically occur in the spring and summer and are controlled by emission of precursor gases, tropospheric chemistry and local meteorology which can be influenced by large-scale synoptic weather regimes.

This paper presents a very high resolution atlas of daily precipitations across the Balearic Islands territory. The generation of this dataset allows not only to set the grounds for future updates ingesting a myriad of observation sources but also aims at providing support to local and network-topology independent studies of precipitation-senstive systems such as ecosystems, water resources and energy systems. As an example, a better understanding of the negative precipitation trends is found.

The IUCN (International Union for Conservation of Nature) Red List classifies species according to their risk of extinction, informing global to local conservation decisions. Unfortunately, important geospatial data do not explicitly or efficiently enter this process. Rapid growth in the availability of remotely sensed observations provides fine-scale data on elevation and increasingly sophisticated characterizations of land cover and its changes. These data readily show that species are likely not present within many areas within the overall envelopes of their distributions.

The Sundarbans mangrove ecosystem, located in India and Bangladesh, is recognized as a global priority for biodiversity conservation and is an important provider of ecosystem services such as numerous goods and protection against storm surges. With global mean sea-level rise projected as up to 0.98 m or greater by 2100 relative to the baseline period (1985–2005), the Sundarbans – mean elevation presently approximately 2 m above mean sea-level – is under threat from inundation and subsequent wetland loss; however the magnitude of loss remains unclear.

The 13th century CE Sun Temple at Konark in Odisha, India, is believed to have been built at the mouth of an ancient river named Chandrabhaga. This mythical river figures prominently in ancient literature, although at present no river exists in the proximity of the Konark Sun Temple. This study investigates the possibility of existence of a ‘lost’ river system near Konark through integrated geological and geophysical exploration in conjunction with historical evidence.

Cannabis agriculture is a multi-billion dollar industry in the United States that is changing rapidly with policy liberalization. Anecdotal observations fuel speculation about associated environmental impacts, and there is an urgent need for systematic empirical research. An example from Humboldt County California, a principal cannabis-producing region, involved digitizing 4428 grow sites in 60 watersheds with Google Earth imagery. Grows were clustered, suggesting disproportionate impacts in ecologically important locales.

Anthropogenic aerosols are a key factor governing Earth’s climate, and play a central role in human-caused climate change. However, because of aerosols’ complex physical, optical, and dynamical properties, aerosols are one of the most uncertain aspects of climate modeling. Fortunately, aerosol measurement networks over the past few decades have led to the establishment of long-term observations for numerous locations worldwide.

Worldwide riverine thermal pollution patterns were investigated by combining mean annual heat rejection rates from power plants with once-through cooling systems with the global hydrological-water temperature model variable infiltration capacity (VIC)-RBM. The model simulates both streamflow and water temperature on 0.5° × 0.5° spatial resolution worldwide and by capturing their effect, identifies multiple thermal pollution hotspots.

Matthew Hansen uses satellites to spot deforestation as it happens.

The aim of this study is to determine landscape dynamics in the classified forest of Haut-Sassandra (CFHS) during the periods of conflict in Ivory Coast (or Côte d’Ivoire). To achieve this, the land cover of this protected area was determined by classifying satellite images obtained before, during and after the conflicts, and via ground surveys. Metrics of landscape ecology were calculated. A ground campaign for observing the CFHS’s flora and damages incurred was carried out using a sampling of eighteen 500 m-long transects.
