Yes, if we want this planet to remain a place that is hospitable for humans and other species in the future, then we need to act now. A vast majority of scientists agree that global warming is real and that we can do things to reverse or slow its harmful effects.
In a world where people who are too lazy to even check the news with out seeing it on a social network what makes people think they would go out of their way to something they don't feel is either gonna have an affect or benefit them. We live in a lazy world and because of this government action needs to be taken to ensure the safety of our planet.
I am currently studying biology and the Pangaea mega-continent, with the climate changes that have occurred in the past. Most of what has already happened on Earth ought to be considered a possibility for the future. Major glaciations have occurred, and temperature changes are already in progress, right here and now. Dramatic climatic shifts have always happened and should be taken seriously today, before history repeats itself.
Countries with large economies have a moral obligation to deal with climate change and the environment. Countries that are just getting their economies going can't afford the massive environmental efforts that developed countries can afford. Climate change is a global issue, and one that needs the sort of immediate action that large economies can muster.
According to reports by the EPA, there are huge shifts in climate change that are uncharacteristic of previous historical climate shifts. Water levels are rising, temperatures are rising, and the air is becoming more polluted. If we do not respond to these concerns, we are not only endangering the lives of many species, but of our own. If I concede the point that the climate shift is a natural occurrence, my point will remain the same. We have used up many natural resources and deforested much of the rain forests that contributed to the homeostasis of the planet. Therefore, the results of this climate shift are very unpredictable and, therefore, extra measures should be taken to return the earth to its previous state.
Yes, I agree that the U.S. and other nations need to take immediate, large-scale action to stop climate change because, if they don't, irreversible damage can be done, and we will all be stuck wishing we had done something to prevent it. All countries should ban together, come up with a list of dangers to our climates, find out what is causing the danger, then take action to stop these dangers from continuing. I think a lot of chemicals and other things are knowingly allowed into our environment each day, even though they are dangerous. If the government got tough and banned these chemicals, could we slow down climate change? I think so.
Animals or plants aren't hurting the environment at all. All the damage is the fault of humans, and it's not going to repair itself. Without clean water and air, none of us will survive, so we need to get our act together.
Climate change isn't something we should be taking lightly. People are more important than profits and the effects of the sharp increase in CO2 is known by scientists to increase the temperature on Earth. This is known via ice core samples that tell us the conditions on Earth over the past few hundred thousands of years. The increase in CO2 seen over the last 100 years is far more dramatic than anything we know to have occurred on Earth in the past, and must be acted on to ensure the health of our children.
Climate change is a real problem facing the world today. U.S. greenhouse gas emissions are up to 6.089 billion tCO 2e/year (metric tons of carbon dioxide equivalent per year), even with certain imposed restrictions. Developing countries like China have little to no restrictions on greenhouse gas emissions. These greenhouse gases cause our atmosphere to absorb and re-emit infrared radiation back to earth, causing the planet to heat up.
Global warming has not been proven in a lab setting or with scientific data. The data used in the media is inaccurate. The bottom line is that the Earth changes temperatures every so many years. If one was to study facts, they would find out that the Earth is actually cooling down, rather than heating up.
There's no reason to do this because there's no reliable, unbiased data that supports the belief that man is contributing to what is certainly a natural, cyclic climate. Total Solar Irradiance (TSI) and oceanic oscillations are the cause of climate cycles, warm or cool (remember the next ice age scare of the 70s?)
I am a big believer that the sun has more effect on the climate than man-made greenhouse gases. We seem to be going through a cooling period, where the winters are colder, over this past decade. The weather has a way of humbling scientists that try to make long term predictions. Drastic actions to stop climate change means major breaking of the economy, when the world is suffering an economic downturn already.
If you go back and look at all the weather data for the last 100 years, the weather has not been any hotter when you average it out. We might have 2 or3 years of really hot summers and then we have milder summers in other years.
