The history of glacier length fluctuations serves as a reliable indicator of the past climate. In this paper, a numerical flowline model has been used to study the relationship between length variations of Chhota Shigri glacier and local climate since 1876. The simulated front positions of Chhota Shigri glacier are in agreement with those observed. After a successful simulation of the past retreat, the model was also used to predict future evolution of the glacier for the next 100 years under different climatic scenarios.

This paper assesses whether ExxonMobil Corporation has in the past misled the general public about climate change. We present an empirical document-by-document textual content analysis and comparison of 187 climate change communications from ExxonMobil, including peer-reviewed and non-peer-reviewed publications, internal company documents, and paid, editorial-style advertisements ('advertorials') in The New York Times.

The Eliassen–Palm flux and Plumb wave activity flux are calculated using the European Centre for Medium-Range Weather Forecasts interim reanalysis daily dataset to determine the propagation of Rossby waves before a North American cold wave in January 2014. The results show that the upward wave activity fluxes mainly come from planetary waves 1 and 2, which provide a stable circulation background for the influence of the subplanetary-scale waves 3 and 4.

This report provides a summary of the Raising Risk Awareness project’s results and learning. In summarising both the project’s activities and stakeholders’ responses, this report may prove useful to scientists, development agencies and civil society-based organisations who wish to build on this foundational work in the future.

Ice-albedo feedback due to the albedo contrast between water and ice is a major factor in seasonal sea ice retreat, and has received increasing attention with the Arctic Ocean shifting to a seasonal ice cover. However, quantitative evaluation of such feedbacks is still insufficient. Here we provide quantitative evidence that heat input through the open water fraction is the primary driver of seasonal and interannual variations in Arctic sea ice retreat.

Anthropogenic climate change is expected to strengthen the vertical wind shears at aircraft cruising altitudes within the atmospheric jet streams. Such a strengthening would increase the prevalence of the shear instabilities that generate clear-air turbulence. Climate modelling studies have indicated that the amount of moderate-or-greater clear-air turbulence on transatlantic flight routes in winter will increase significantly in future as the climate changes.

This policy brief concludes that, from the climate science perspective, results show the 2016-17 drought is less severe than the 2010-11 drought in Lamu, while in Marsabit they are comparable. In general, the return time of the event over the regions analysed was low, meaning that this kind of drought is a relatively common event.

This Interim Report on Climate Change over India prepared by the Centre for Climate Change Research (CCCR) in the Indian Institute of Tropical Meteorology (IITM) Pune, is intended to provide a brief overview of (a) Updated assessment of observed climate change over India (b) Future climate projections over India (c) Development of the IITM Earth

Discriminating the climate impacts of half-degree warming increments is high on the post-Paris science agenda. Here the researchers argue that evidence from the observational record provides useful guidance for such assessments.

The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration.
