Is human activity a substantial cause of global climate change?

Some people argues rising levels of atmospheric greenhouse gases are a direct result of human activities such as burning fossil fuels, and that these increases are causing significant and increasingly severe climate changes including global warming, loss of sea ice, sea level rise, stronger storms, and more droughts. For other people human-generated greenhouse gas emissions are too small to substantially change the earth’s climate and that the planet is capable of absorbing those increases.

Dear Daniel, I totally agree with you, and it’s a shame that people such as Donald Trump think that global warming doesn’t exist, the changes that you can observe nowadays are a consequence of human actions and will be reflected in the future as a negative impact on humans, this is worrying, since the effect is starting in countries such as China, the United States and Arabic Countries.
