Most common immigration problems

- Getting permission to stay in the country longer than you originally intended;
- Getting permission to do something which you are not allowed to do, for example, get a job;
- Bringing relatives into the country;
- Being threatened with deportation from the country where you are;
- Being held by the immigration authorities in a detention centre;
- Wanting for a passport and not knowing whether you are entitled to a country passport or some other passport;
- Wanting to apply to become a country Citizen;
- If you are already living in some country but you want to travel (for example, to go on holiday), you have to question whether you will be allowed back into the other country;
- The permission to use state services or claim benefits, for example, education, health services, council housing, social security benefits, housing benefits, council tax benefit;
- The right to vote;
- A relative or friend being refused entry to country when arriving at an airport or port;
- Problems with people living in the country where you arrived (discrimination).

Discrimination by Age, Sex, Gender and Ability

We are all different and that makes us equal.

Stop discrimination and the world will be a better place!

Wake up!

You have a choice!

Let's stop to ruin the world and start to improve it!

We have the duty of save the world!

Don't let the planet give up of us, so don't give up of the planet!

Wake up!
Take the best choice!
Help the environment!

The memory of climate

More generally, most forms of internal variability in the climate system can be recognized as a form of hysteresis, meaning that the current state of climate reflects not only the inputs, but also the history of how it got there. For example, a decade of dry conditions may cause lakes to shrink, plains to dry up and deserts to expand. In turn, these conditions may lead to less rainfall in the following years. In short, climate change can be a self-perpetuating process because different aspects of the environment respond at different rates and in different ways to the fluctuations that inevitably occur.

Ocean variability

On the scale of decades, climate changes can also result from interaction of the atmosphere and oceans. Many climate fluctuations — including not only the El Niño Southern oscillation (the best known) but also the Pacific decadal oscillation, the North Atlantic oscillation, and the Arctic oscillation — owe their existence at least in part to different ways that heat can be stored in the oceans and move between different reservoirs. On longer time scales ocean processes such as thermohaline circulation play a key role in redistributing heat, and can dramatically affect climate.

glaciation

Glaciers are recognized as being among the most sensitive indicators of climate change, advancing substantially during climate cooling (e.g., the Little Ice Age) and retreating during climate warming on moderate time scales. Glaciers grow and collapse, both contributing to natural variability and greatly amplifying externally forced changes. For the last century, however, glaciers have been unable to regenerate enough ice during the winters to make up for the ice lost during the summer months (see glacier retreat).
The most significant climate processes of the last several million years are the glacial and interglacial cycles of the present ice age.[citation needed] Though shaped by orbital variations, the internal responses involving continental ice sheets and 130 m sea-level change certainly played a key role in deciding what climate response would be observed in most regions. Other changes, including Heinrich events, Dansgaard–Oeschger events and the Younger Dryas show the potential for glacial variations to influence climate even in the absence of specific orbital changes.

clima change

Climate change is any long-term significant change in the “average weather” that a given region experiences. Average weather may include average temperature, precipitation and wind patterns. It involves changes in the variability or average state of the atmosphere over durations ranging from decades to millions of years. These changes can be caused by dynamic processes on Earth, external forces including variations in sunlight intensity, and more recently by human activities.
In recent usage, especially in the context of environmental policy, the term "climate change" often refers to changes in modern climate (see global warming). For information on temperature measurements over various periods, and the data sources available, see temperature record. For attribution of climate change over the past century, see attribution of recent climate.
