State of the climate in Asia 2023
Asia remained the world’s most disaster-hit region from weather, climate and water-related hazards in 2023. Floods and storms caused the highest number of reported casualties and economic losses, whilst

In their policy forum ("The limits of consensus," 14 September 2007, P. 1505), M. Oppenheimer et al, make several misleading statements. They suggest that a premature drive for consensus led Working Group I to understate the risk of large future sea-level rise in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (WGI-AR4).

Large swathes of the usually humid southern China are currently facing drought, described as the worst in 50 years. The drought has left over a million people short of drinking water and has shrunk
The Turonian (93.5 to 89.3 million years ago) was one of the warmest periods of the Phanerozoic eon. It has been argued that there may have been several stages of continental ice growth during the period, reflected in both erosional surfaces and geochemical records associated with possible glaciation-induced sea-level falls.
In a research by paleoceanographer Andre Bornemann of Leipzig University in Germany and his colleagues analyzed apparently unaltered Foraminifera picked from sediment core drilled from Demerara Rise beneath the western equatorial Atlantic. Following a classic technique, the researchers measured oxygen isotopes in the forams' shells. They found a sharp shift toward the heavier oxygen-18 isotope in both surface and bottom dwelling forams from 91.2 million years ago.
some winter crops (wheat, mustard, barley and chickpea) in northwest India was evaluated on the basis of historic records and through a dynamic crop growth model, WTGROWS. The optimal date of sowing was also evaluated in view of the increase in seasonal temperature. The yield of these crops, especially wheat, already showing signs of stagnation in most places of northwest India, is most likely to be affected by temperature
As the world warms, the plants that billions of people depend on for their food are likely to become less nutritious. That's the worrying conclusion of an analysis of more than 40 studies investigating how crops will react to increasing levels of carbon dioxide in the atmosphere.
An outstanding climate anomaly 8200 years before the present (B.P.) in the North Atlantic is commonly postulated to be the result of weakened overturning circulation triggered by a freshwater outburst. New stable isotopic and sedimentological records from a northwest Atlantic sediment core reveal that the most prominent Holocene anomaly in bottom water chemistry and flow speed in the deep limb of the Atlantic overturning circulation begins at '8.38 thousand years B.P., coeval with the catastrophic drainage of Lake Agassiz.
<p>Mangrove ecosystems are threatened by climate change. We review the state of knowledge of mangrove vulnerability and responses to predicted climate change and consider adaptation options. Based on available
Most climate change models predict that this global phenomenon will have severe impacts on small farmers, particularly in developing countries. Increasing temperatures, droughts, heavy precipitation and other extreme climatic events could reduce yields by up to 50 percent in some regions, especially in drylands.
This report examines the development dilemma that India faces. India has an extremely large economy and a rapid rate of economic growth, so will emit large amounts of GHG. However, the population overall is very poor, and development will require access to basic energy services; meanwhile the Government is Very nervous of taking on costly decarbonisation commitments.
