Asia’s glaciers will loose at least one third of their ice mass this century

At a global temperature rise of 1.5 °C about one third of the present-day ice mass stored in Asia’s high mountains glaciers will be lost by the end of the century. But it may be much worse.

What if the past is the key to the future? We may start losing coastal deltas 50 years from now

Sea level rise slow down 7500 years ago started delta formation globally. What if the past is a key to the future? Will accelerating sea level rise this century be a tipping point of delta collapse?

European heat waves like in the 1950s: what if climate hadn’t changed?

If Europe’s climate hadn’t changed since the 1950s, the number of hot days with maximum temperature over 35 °C would have been 25-50% less.

Wildfires in Portugal: is past trend of forest cover increase now ‘going up in smoke’?

Portugal’s forest area has increased since 1875 from 7% to nearly 40% of the country’s mainland area. This trend has reversed since 1990, however, likely due to wildfires and their mismanagement.

Deltas at the Greenland coast are growing due to a warmer climate

Since the 1980s, the deltas at the Greenland coast have been extending into the sea due to increased freshwater runoff from the ice sheet and more sediment transport to the coast.

Warmer water due to climate change may lead to more algal blooms, or less

Lake warming due to climate change makes algae-poor lakes get poorer and algae-rich lakes get richer. Tailor-made management is needed to prevent negative consequences for ecology and society.

Under 2°C global warming the permafrost extent of the Northern Hemisphere will decrease by about 25%. Ground will settle owing to permafrost thaw, 4-15 cm on average, but up to several metres locally.

More hurricanes to hit Western Europe. Ireland and the UK are hit by Ophelia, the worst cyclone to hit this part of Europe in 50 years. A scenario already projected by Dutch scientists in 2013.

“Large wildfires, out of control according to the media, rage across California. Again!” No, this is not the start of a recent article; it’s the start of an article we’ve published last year.

Plant species on Mediterranean islands can migrate into more favourable ecological niches when climate changes. Many islands may be too small, however, and certain species may not survive.

The Netherlands is about to get a new government. Climate change will be a spearhead and one of the Ministers will be a Minister for "Economic and Climate Affairs".

After 2007 mackerel became more abundant in northern Atlantic waters. This triggered a conflict over fishing quotas between the European Union (EU), Norway, Iceland, and the Faroe Islands.

More people will probably be exposed to shallow, rapid-moving landslides. The number of deep-seated, slower landslides, that cause a lot of economic damage, will probably decrease.

In an urban office building without active cooling, the number of lost working hours may quadruple between now and 2100. Effective adaptation measures may reduce this up to 90%.

The seasonal timing of river floods across Europe has been changing since 1960. Floods now occur earlier in northeastern and western Europe, and later around the North Sea and Mediterranean coast.

On average 28,000 people die every year in 27 European countries due to heat waves. 0.61% of all mortality in the examined 27 countries is excess mortality caused by heat waves.

Sea level rise reconstructed step by step. Submerged steps of water stairs of palaces on the Grand Canal provide an exceptionally long series of data on sea level rise.

Only 5-10 cm of sea-level rise may more than double the frequency of coastal flooding in the Tropics as early as 2030. Some of the largest cities in the world may face a dire future.

Even if the planet only warms up by 1.5 °C, the target of the Paris agreement, one-third of all Asian glaciers will have melted by 2100, according to research carried out by Dutch scientists.

Plants respond to global warming by advancing their onset of flowering in spring. This advancement is faster in the north of Europe and in the mountains than in the south.

Heat-related illness and the economic cost of avoiding it is a serious issue that should be kept in mind when discussing the benefits and economic cost of climate change mitigation.

Along the US east coast sea level rise may lead to strong amplification of high frequency flood events. Along the west coast, on the other hand, amplification is strongest for lower frequency flooding

Even under the 1.5°C and 2°C warming targets of the Paris agreement, drought risk increases significantly in the Mediterranean, central Europe, the Amazon, and southern Africa.

In Spain and Portugal the number of heat waves, their duration and intensity will increase in the course of this century. At the same time, less cold spells will occur, and they will become less cold.

In a warmer world, hydrological impacts of climate change are more intense. Heavy rainfall and highest river flows further increase, lowest flows decrease. In addition, these changes affect wider area

The rate of global mean sea level rise has increased over the last two decades, mainly due to increased land ice loss from Greenland. Over the period 2004-2015 sea level rose about 3.5 mm per year.
