What will happen if the temperature keeps on increasing?

If the global temperature rises by two degrees Celsius, alpine glaciers and rivers will begin to evaporate, and mountainous regions will see more landslides as the permafrost that has kept them together melts. Sea levels might rise by a metre by 2100, displacing 10% of the world's population.

If the temperature increases by four degrees, many low-lying countries would be affected by sea level rise. Some estimates say that almost all of Bangladesh would be under water. Other studies have suggested that up to half of London could be submerged.

Scientists believe that if the temperature rises much further it will cause major problems for the Earth's climate system. The extra heat can cause ice sheets to melt, leading to more water being released into the atmosphere, which will then go on to melt more ice.

This cycle won't stop until there is no more ice left in the world. Scientists think that by around 2500 AD it will have been so hot that most of the ice in the world has melted.

How does carbon dioxide get trapped in ice? Carbon dioxide molecules are very stable and don't easily bind to other substances. But when water gets cold, the energy needed to break these strong chemical bonds becomes free energy that can do work. So when ice is formed or changes state, some of this free energy is used to trap carbon dioxide inside the crystal structure of the ice.

What will happen if the world heats up by 4 degrees?

Warming of 4 degrees Celsius will most certainly result in a sea-level increase of 0.5 to 1 meter, and maybe more, by 2100, with several meters more to come in the following centuries. Only if warming is maintained far below 1.5 degrees Celsius can sea-level rise be confined to less than 2 meters.

At 5 degrees Celsius, many parts of Antarctica will be able to support ice shelves, but they will be smaller than today. At 9 degrees Celsius, all of Antarctica will be ice free during some part of the year. At 11 degrees Celsius, all marine species will be affected except for those that can live at very deep depths. There will be major ecological changes across the planet due to the loss of heat-sensitive organisms like coral reefs and rainforests.

All together, these results show that we have only a limited time to take action against climate change. If we want to keep global warming below 2 degrees Celsius, we need to completely stop burning fossil fuels (and remove all carbon dioxide emissions already released) by 2050 at the latest. Otherwise, there will be no safe place on Earth for our children and grandchildren to live.

What happens if the temperature rises 2 degrees?

More than 70 percent of the Earth's coasts would face a sea-level rise of more than 0.66 feet (0.2 meters) if global warming exceeds 2 degrees Celsius, resulting in increased coastal flooding, beach erosion, salinization of water sources, and other effects on humans and biological systems. Some estimates suggest that this could cause up to $90 billion in damage each year.

Every region of the world will be affected by a 2 degree Celsius increase in average global temperature, but some will be affected much more than others. Low-lying islands will be particularly at risk from climate change. Warmer oceans will cause greater ocean expansion, which leads to island shorelines being pushed inland. This occurs with both current-day and past climate changes that have been measured in ice cores and coral reefs.

Atmospheric carbon dioxide concentrations will continue to rise for many centuries after global temperatures return to normal. The amount of energy that is trapped by greenhouse gases around the planet is more than enough to heat up the planet beyond what it is now. As long as we keep emitting carbon dioxide and other greenhouse gases into the atmosphere, then even after the sun starts shining again there will still be reason to worry about future solar storms causing further global heating.

The world has already warmed by 1 degree Celsius since the beginning of the industrial era, and there are no signs that it is going to stop anytime soon.

What happens if the Earth warms up a few more degrees?

The temperature equilibrium between solar radiation and space temperature changes by -273 degrees if the planet heats a few degrees further. The glaciers will melt faster. Human existence will be under extremely perilous circumstances. The land's water-retaining zones, such as ponds and lakes, will dry up. Cities and industrial facilities will become uninhabitable. Most animal life will be killed off. Only those species that can adapt themselves to new conditions will survive.

The Earth has already warmed by 0.9 degrees since the beginning of the Industrial Revolution. If all the carbon dioxide emitted by human activities was removed from the atmosphere, the Earth would heat up by about 3 degrees.

Based on current trends, scientists think we'll reach 2 degrees Celsius (3.6 degrees Fahrenheit) of global average temperature increase by 2100. Some studies suggest that even 1 degree increase could have serious consequences for sea level rise, drought, insect extinction, and disease prevalence.

Every degree increase above pre-industrial levels increases the likelihood of major climate change impacts by 20%. That means if we keep warming the planet, there is a high chance that many parts of the world will experience severe environmental damage or even total devastation.

However, there are ways to reduce the amount of CO2 in the atmosphere without sacrificing our standard of living.
