Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.

Scientists dig a snow pit in the winter and measure the snow accumulation, calculate its density, and then convert it to water equivalent. This tells them the annual growth of the glacier. To calculate melting, they drill a stake into the ice at the beginning of summer and measure the height sticking above the surface.

To see if a glacier is growing or shrinking, glaciologists check the condition of snow and ice at several locations on the glacier at the end of the melt season. Generally, the difference in thickness of snow from the previous measurement indicates the glacier’s mass balance—whether the glacier has grown or shrunk.

Mass balance of a glacier (also referred to as “surface mass balance”) is the difference between the snow accumulated in the winter and the snow and ice melted over the summer. In the ablation (melt) zone, measurements are made by drilling stakes into the glacier at the onset of the ablation season (spring).

While there is no global standard for what size a body of ice must be to be considered a glacier, USGS scientists in Glacier National Park use the commonly accepted guideline of 0.1 square kilometers (about 25 acres) as the minimum size of a glacier.

Glacial motion can be fast (up to 30 metres per day (98 ft/d), observed on Jakobshavn Isbræ in Greenland) or slow (0.5 metres per year (20 in/year) on small glaciers or in the center of ice sheets), but is typically around 25 centimetres per day (9.8 in/d).

The annual melt rate from 2015 to 2019 is 71 billion metric tonnes more per year than it was from 2000 to 2004. Global thinning rates, different than volume of water lost, doubled in the last 20 years. Half the world’s glacial loss is coming from the United States and Canada.

Using 20 years of recently declassified satellite data, scientists calculated that the world’s 220,000 mountain glaciers are losing more than 328 billion tons (298 billion metric tons) of ice and snow per year since 2015, according to a study in Wednesday’s journal Nature.

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. Ice actually flows down valleys like rivers of water .

10 Ways to Stop Global Warming

1. Change a light. Replacing one regular light bulb with a compact fluorescent light bulb will save 150 pounds of carbon dioxide a year.
2. Drive less.
3. Recycle more.
4. Check your tires.
5. Use less hot water.
6. Avoid products with a lot of packaging.
7. Adjust your thermostat.
8. Plant a tree.

What solutions to consider? Changing our main energy sources to clean and renewable energy. Solar, Wind, Geothermal and biomass could be the solution. Our transport methods must be aligned with environmental requirements and reduce their carbon footprint.

Increases in pests and diseases and more frequent and intense droughts and floods, reduce the availability of food. Heat-stress causes poor yields, or worse, crop failures. Reducing short-lived climate pollutants gives us our best chance to rapidly limit global temperature rise and reduce the risks to food security.

Prepare yourself for extreme weather

1. in a heat wave wear sun screen and a hat and drink plenty of water.
2. snowfall and icy weather can make people more prone to falls so take care.
3. weather can affect transport networks, making it difficult to get around.

Here are five things you can do to stay well and reduce your carbon footprint in a world affected by climate change:

1. Pay attention to extreme weather and pollution advisories.
2. Prevent the spread of disease.
3. Leave a minimal footprint.
4. Use low impact methods of transportation.
5. Choose thoughtfully.

These strategies can help you cope together.

1. Talk about it. You might worry that discussing climate change will make your kids feel worse, but talking through fear often helps dull its intensity.
2. Take action as a family.
3. Appreciate nature together.

In How to Prepare for Climate Change, David Pogue–a five-time Emmy Award-winning technology and science correspondent for CBS Sunday Morning, New York Times bestselling author and host of science specials on PBS NOVA–offers a sensible, deeply researched guide with practical advice for how everyday people can ready …

Climate change affects human health and wellbeing through more extreme weather events and wildfires, decreased air quality, and diseases transmitted by insects, food, and water.

A variety of environmental factors can increase the likelihood of anxiety. For example, a person’s family composition, their cultural and religious upbringing, and many other childhood experiences can influence anxiety levels, according to a 2018 review.

By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.

Heat waves will become more frequent and severe around the world, affecting hundreds of millions—or even billions—of people if we don’t act.

Climate change driving entire planet to dangerous ‘global tipping point’ Oceans, and the corals that live in them, are under extreme stress from climate change, and could be at the point where too much damage has been done to recover from it.

Human activity is causing environmental degradation, which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution.

Scientists agree that the planet is warming up faster than ever because of the vast amount of greenhouse gases that humans are pumping into the atmosphere. This includes activities such as burning fossil fuels (coal, oil and gas), driving cars and cutting down forests.

High temperature extremes and heavy precipitation events are increasing, glaciers and snow cover are shrinking, and sea ice is retreating. Seas are warming, rising, and becoming more acidic, and flooding is become more frequent along the U.S. coastline.

Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1,500 years. They go on to predict that emissions have been so high that it will not.

The Arctic, Africa, small islands and Asian megadeltas are regions that are likely to be especially affected by future climate change. Within other areas, some people are particularly at risk from future climate change, such as the poor, young children and the elderly.

Climate change has affected Japan drastically. The precipitation in summer in Japan will increase steadily due to global warming (annual average precipitation will increase by 17% in Scenario B1 and by 19% in Scenario A1B during the period 2071–2100 compared to that of 1971–2000).

The Germanwatch institute presented the results of the Global Climate Risk Index 2020 during COP25 in Madrid. According to this analysis, based on the impacts of extreme weather events and the socio-economic losses they cause, Japan, the Philippines and Germany are the most affected places by climate change today.
