Sydney's record-breaking weather juggernaut rolls on, with summer confirmed as the city's hottest for both days and nights over records stretching back 157 years.

The continent of Antarctica officially has a new record high temperature of 63.5 degrees, scientists from the World Meteorological Organization (WMO) announced Wednesday.

In a typical February, much of the United States is in the grip of cold winter weather - not this year.

Study claims 50 percent chance of major chill before end of the century.

• Scientists from the World Meteorological Organisation (WMO) say there is a possibility of a new El Niño event forming later this year.

The 2015-16 El Niño was the strongest since the record event of 1997-98

Understanding the sources and evolution of aerosols is crucial for constraining the impacts that aerosols have on a global scale. An unanswered question in atmospheric science is the source and evolution of the Antarctic aerosol population.

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.

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.
