i'm tenzin shakya belonging to upper tcv school and i'm very much glad to participate in this my climate project.here i want to share brief imformation about thre changes hitted by human activity. "Climate change is the only thing that I believe has the power to fundamentally end the march of civilization as we know it, and make a lot of the other efforts that we're making irrelevant and impossible,"  as said by former US President Bill Clinton at the 2006 World Economic Forum in Davos, Switzerland.
Today there is little doubt that climate change is occurring, and that negative consequences are beginning to emerge. Many observers point to the increasing number of severe storms, floods, and heat waves in recent years as indicators of changing climatic conditions. The vast majority of related scientific research confirms a direct relationship between human activity, the rising levels of greenhouse gases (GHG) in the atmosphere, and climate change in the form of global warming. The Earth's average temperature has risen by around 0.6 °C over the past century years due to human activity. Although it may not sound like much, this slight change has already altered rain and snowfall patterns, and has resulted in a rise in sea levels and the gradual retreat of most non-polar glaciers. the rate of climate change is increasing. If there was one ultimate energy source to break the world’s addiction to fossil fuels, expert Robert Hirsch says the world would be using it by now.

While wind turbines and solar panels remain the popular symbols of a future clean-energy economy, scientists and engineers are busy cooking up a plethora of new technologies to save and produce energy.

Finding alternatives to climate-damaging oil and coal energy is all about diversification. None of the proposed "climate solutions" could stabilize greenhouse gas emissions or meet the world's energy demands alone. But taken together, they could be important pieces of the puzzle.
