Possible influence of anthropogenic aerosols on cirrus clouds and anthropogenic forcing [PDF]

open access: yesAtmospheric Chemistry and Physics, 2008
Abstract. Cirrus clouds have a net warming effect on the atmosphere and cover about 30% of the Earth's area. Aerosol particles initiate ice formation in the upper troposphere through modes of action that include homogeneous freezing of solution droplets, heterogeneous nucleation on solid particles immersed in a solution, and deposition nucleation of ...

Anthropogenic influences on major tropical cyclone events [PDF]

open access: yesNature, 2018
There is no consensus on whether climate change has yet affected the statistics of tropical cyclones, owing to their large natural variability and the limited period of consistent observations. In addition, projections of future tropical cyclone activity are uncertain, because they often rely on coarse-resolution climate models that parameterize ...

Detecting anthropogenic influence with a multi‐model ensemble [PDF]

open access: yesGeophysical Research Letters, 2002
Averaging results from multiple models has previously been found to improve estimates of the climatology and seasonal predictions of atmospheric variables. Here we describe how a multi‐model mean of the simulated response to greenhouse gas and sulphate aerosol changes may be used to detect anthropogenic influence on surface temperature.

PAN EURASIAN EXPERIMENT (PEEX) - A RESEARCH INITIATIVE MEETING THE GRAND CHALLENGES OF THE CHANGING ENVIRONMENT OF THE NORTHERN PAN-EURASIAN ARCTIC-BOREAL AREAS

open access: yesGeography, Environment, Sustainability, 2014
The Pan-Eurasian Experiment (PEEX) is a new multidisciplinary, global change research initiative focusing on understanding biosphere-ocean-cryosphere-climate interactions and feedbacks in Arctic and boreal regions in the Northern Eurasian geographical ...

The anthropogenic influence on carbonaceous aerosol in the European background [PDF]

open access: yesTellus B: Chemical and Physical Meteorology, 2009
To constrain the relatively uncertain anthropogenic impact on the organic aerosol load, radiocarbon analyses were performed on aerosol samples, collected year-round, at six non-urban sites including a maritime background and three remote mountain stations, lying on a west-east transect over Western Europe.

Detectable anthropogenic influence on summer compound hot events over China from 1965 to 2014

open access: yesEnvironmental Research Letters, 2022
Compared with independent hot days or nights, compound hot extremes have more adverse effects on society. In this study, hot extremes are categorized into three types: independent hot days, independent hot nights and compound hot events combining daytime

EPIDEMIOLOGICAL ASPECTS OF ANTHROPOGENIC INFLUENCE TO LEPTOSPIROSIS EVOLUTION

open access: yesИнфекция и иммунитет, 2014
. It has been shown that practical activity of people during the last several decades exerts significant influence not only for frequency of population’s contacts with leptospirosis foci, but also for changes of mammalian types which are reservoirs and ...
